With customer reviews, it is easy to condense benefits and drawbacks. That said, it is sometimes difficult to stay focused with all of the reviews from countless brands. These mattresses are given mixed reviews by customers. Some report feeling comfy in their new bed, but others report not feeling as good.
Having a supportive mattress is important for a night's sleep. Most like the feel of this mattress for the first few months, but there are some reports of problems with support over the long term. Do some additional research on the mattress to make sure it fits your body type.
Many look for good edge support as a way to be comfortable getting in and out of bed. These mattresses are okay in terms of edge support, but there may be more declining edges over time.
Bowling Ball & Density Tests
In tests that measure the density and supportiveness of these mattresses, these mattresses have fairly even support. Some folks have mentioned that support may degrade over time for some.
These mattresses get mixed reviews from customers on lasting comfort. We all want a mattress that stays just as cozy in 10 years as it feels now, but sadly not all mattresses last a long time. If a mattress with mixed feelings on durability is on your short list, make sure to take an extra look at the policies on return to make sure you are protected.
If you are thinking about this one, do more research below to learn if this mattress will work for you. Unfortunately, not all customers give them good ratings. Some were perfectly satisfied with their mattress, but others had complaints about their comfort.
These mattresses do well with support vs many other competitors. They offer the support needed to align the vertebrae and help sleepers feel comfort. Reviews describe the mattresses as quite supportive and and don't mention initial issues with loss of resiliency.
Edge support is important for those that sit or lay close to the edge of the mattress and desire even support throughout. These mattresses have good edge support for those that need it.
Bowling Ball & Density Tests
A bowling ball on top of the mattress is a good way to measure support and firmness. These mattresses provide an even supportive structure throughout the mattress.
Good craftsmanship, materials, and quality control will more than likely lead to good durability. Some sleepers may have disagreements with companies if they don't have these attributes. Sadly, customers have mixed feelings about lasting comfort from these mattresses. There are some customers that have complaints about comfort over the short term, while others report a happy night's sleep. Ensure that you take a look at the reviews before you buy.

We bought this mattress over a year ago...had no idea that they sold a separate foundation. Spent months replacing the bunky board we got from Crate and Barrell 2 times and dealing with back pain, even called the mattress mfr. The mattress mfr said they recommend their foundation instead of bunky board. Ordering it today, hopefully it will take care of the problem but paying $50 more than if I bought them together from the start. They need to update the description and recommend the foundation if they don't buy it separately OR don't even sell the mattress alone. Description said it needs a 'solid' foundation...what does that even mean? I had a hard time trying to find a bunky board that is solid wood from many retailers. Crate and Barrel's new bunky board is made of compressed cardboard! A painful process, but I like the mattress.View More Reviews
The mattress is definitely on the firm side but we both find it about right. After 11 months, the bed seems to be wearing very well... no signs of change in feel or shape. The adjustable bed is used in zero gravity every night for one of us and not used at all for the other. The adjustable bed works well for back sleepers but not side or stomach sleepers.
This bed is the best we have ever slept on, even 6 years later. We have the queen, and now want a Cali king (we now have a dog sleeping with us), and will be buying another one of these latex matresses from Costco. This one will go into the guest room, and it looks brand new. It has not settled or sagged at all, even though it is used every night, by 2 people. It is NOT hot, either. The memory foam mattress we bought from Costco first, was hot, however. So we returned the memory foam and got this latex mattress. We are so happy!!!
I did what i thought was plenty of research before i bought this bed.. I've waited a full year to try and get used to it, and kept telling myself and my spouse it would get better. Not only was it hard and uncomfortable but, from 3 months on, it had big depression on both sides. It seemed to get worse , not better! The only good thing is i bought it from Costco, so they agreed to take it back, no problem! Yea Costco!!
I bought this bed on July 7, 2016. It was my first Costco online shopping. As in warehouse shopping, the online service was very good. The delivery company did not call me to confirm the delivery time but Joshua and Carlos did great in the delivery of the bed and setting it up. Brandon at the distribution center was excellent. I could test the bed before the purchase. The latex mattress feels cool in summer compared to other types of mattresses. I hope I enjoy my bed for many years to come. I love shopping at Costco!!!
I've purchased 3 of these mattress so far. The first one about 3 years ago, then another one the following year and another one a couple months ago. the first one was in a guest room and the other two were for two of my kids who loved the bed when they slept on it while visiting!
I bought this bed over 2 years ago, maybe 3 years now. My husband was a reluctant buyer, because we are only early 40's :) He thought adjustable was for the nursing home. But he had enjoyed it just as much. It hasn't helped his snoring, but he enjoys the leg elevation and massage features after a tough day or workout, and elevation of his head when congested. I have had a couple of back injuries from car accidents, and sleep considerably better on this bed than ANY OTHER!! We had a memory foam before this. This is NOT memory foam. Memory foam sinks in with your weight, then when you turn over you fall back into the rut you created. Ours was also hot. This foam doesn't radiate heart back at you. I love that! It doesn't sink in. It has great support. It is nice to be able to sleep elevated without getting up in the middle of the night to prop up or go to the recliner. My bed sleeps just like it did almost 3 years ago. No sagging, indentions, or soft spots. It does creak a little when adjusting, nothing a little wd-40 can't fix. The base and massage features still work like a top. No problem! Good buy!
Purchased and received this split King organic mattresses with adjustable bases on April 8th, 2016. What a great product! Both my husband and I absolutely love our mattresses! The adjustable bases fit perfectly inside our existing bed frame, and the mattresses are sooooo very comfortable. I have always been a side sleeper, but no more! I'm able to easily sleep on my back now. Since I am a professional singer, this is a real plus for me. Also, the adjustability allows me to (among other things) raise my head ever so slightly to allow for sinus drainage as well as legs for additional perfectly tweaked comfort. The mattress cover is soft and also feels luxurious. A 3 inch layer of softer 19 ILD natural latex perfectly compliments the firmer 32 ILD layer underneath it to softly cradle with no pressure points yet support my body superbly. Adjustable base works great. Fully articulates for customization. Zero Gravity pre programmed position is heavenly! Don't wait. Buy this now!!! You'll be glad you did! Great price and great product. Thanks Sleep Science - Well done!
We got this bed a couple of months ago. It is very comfortable. Unaware another person is in the same bed. Mattress is fine for us, not too firm and not too soft. No odor.
Delivery company had great personnel.
One side had a control box (located under the bed) that failed in the first few hours. Costco called the company and we had a new one installed by the company in a few days.
I would suggest going to check out Dreamfit mattress covers (they come in twin xl and their kings sheets (2 twin xl bottom sheets with one King top sheet. Their bottom sheets and mattress covers have extra elastic straps to hold the sheets in place. I found these after much research. They stay in place great. Love my bed!!
The mattress delivery was great..even on time. The mattress itself is nice ...no sinking in like foam. Soft and supportive. The adjustable base is great. I do wish the lights on the remotes would come on before you try to poke the right button. Zero gravity setting is awesome!
Its very comfortable. Firm for support but not too firm. My wife & I think it is the best mattress we have slept in. No smell at all.
Disagree with the SUBJECTIVE product details 'Sleep Science comfort scale: medium with a bounce.'
There is missing objective ILD firmness scale info in the product details. For me, 5'3 and less than 120 lb, this is surely a soft latex mattress. In general, The 'soft' designation corresponds to an ILD rating of 19-21. The ILD rating for the medium range is 24-26. After digging yourself, then you find this mattress has ILD 19 on the top 3 inch layer over another 6 inch of 32 ILD.
Best mattress I've ever had
The delivery was early by several days and happened without notice, but luckily we were home to receive the mattress. Unpacking and getting it ready for use was seamless and fast; we didn't have to wait for several hours and slept on the mattress within hours of set-up. So far, the mattress has been comfortable, relieving pressure in all the right places while providing support. I wake without the aches and pains I had come to assume were "normal" as I grow older. I am optimistic that it will continue to be as comfortable for many years to come.
We found this mattress to be extremely firm. We bought a softer topper to help but unfortunately it did not. We have purchased 5 other foam mattresses for ourselves and family members and had been very pleased. This one was just too firm.
Mattress is so firm and comfortable!
We picked this up because I have a bulging disc in my back and even though our other mattress was only 3 years old, it wasn't cutting it. I Love This Bed!!! We've only had a couple of months but so far so good. It's firm the way I need it and supportive. I'm a big guy 6'2 270lbs and it's great for me.
It’s a very good mattress and my mom loves sleeping on it. The mattress is true to the firmness.
Love it feels great for my back and gives plenty of support. Even better you don’t feel any movement when there’s someone next to you.
My husband and I both love this bed! It keeps us from getting overheated (a big issue of mine) and is the perfect firmness. This is our favorite bed after having two other gel cooling foam mattresses that have also been purchased recently. Actually, this is our favorite bed we've ever had and we are both 60.
Very happy with this purchase. Mattress is super comfortable and the firmness just right for both wife and I. (Of course firmness and comfort are subjective and very individual.) The adjustable functions work great and motors are pretty quiet. This was a major factor in our decision as my wife just now had shoulder surgery and sleeping in a reclined position is needed. Packaging and assembly are quality although it would be recommended for 2 people to carry base pieces and mattresses from delivery location to bedroom. Assembly video very helpful. Time will be the teller for durability, but very happy with the purchase and first impression.
the bed is comfortable but its been only 1 week since I have been using it.
Love my new Sleep Science split king bed and adjustable frame. I have only slept in in the last 4 nights so this is an early evaluation. We had a temperpudic for the past several years but this has surpassed that at more than half the cost. So far this bed is my favorite plays to be.
Don't waste your time and money . I had this mattress for more then a month. An every morning i woke up with sore Back .I am been using memory foam mattress for more then 10 years and I never had such a horrible mattress for the price i paid . I am glade i got it from Costco so I could easily return it ..
Good mattress that was delivered one month late. Came rolled up. Have to let it rest for 3-4 days to self inflate and acquire firmness. Since its brand new cannot say how long it will remain firm
Great bed! Sleeping great & elevate when needed without disturbing spouse.
Terrible mattress. Got it delivered after a month after it’s shipped (which is after a week after I ordered). Mattress has some stains on the bottom. Couldn’t spend another month and half without a mattress so opened it. Both Costco and sleep science have deceived me to the core and lost all the respect and trust I had in both these brands. It’s not firm at all, people who love plush would rate this below plush rating. I’ve no energy and time now to deal with the customer service at Costco which discontinued email and chat supports. Staying on phone with them for hours and getting mediocre resolution isn’t worth.
Sleeping was too warm and too firm
So far so good. Hoping for a number of years of the same. Attractive and comfortable.
Very good quality; perfect firmness and it’s a good looking matress.
Mattress was advertised as extra firm and we have found after 2 weeks of sleeping on it the areas where we sleep are already getting soft. Not sure if we will be able to keep it.
My new wife has complained about how much I enjoy sleeping (i.e. I occasionally snore) which apparently keeps her awake. I had a 10 year old sleep number bed that she despised sleeping on because she prefers a firm mattress (firm as in she'd be more comfortable sleeping on the floor than a soft bed) and I was more flexible. She'd mostly started sleeping in the spare bedroom every night because of these two factors when I saw this bed go on sale around memorial day. I figured why not give it a shot and if it didn't work out, we could always return it. Well right from the very first night she noticed a difference where I slept in the zzzz setting and didn't make a sound. That kept up for weeks until we took a small trip and stayed in a hotel room and the snoring returned. We both totally looked forward to coming back to our bed. I've been sleeping comfortably and so had she. Now we can both sleep together in peace.
Super comfortable. Easy to assemble with two people. We love the adjustable settings. Zero gravity is divine!
This is the most firming bed i ever experienced. May be too firm.
Excellent bed great support
It IS a from mattress of very good quality. The massage and adjustability of this bed are great. I’m hoping it softens some, I’ve had it for one month.
After 1 month we are very happy with the purchase. Firm but very comfortable mattress is exactly as described. Motorized stands work very well and seem to be high quality. The price was less than half of what we saw in bedding stores. We should have purchased sooner. My only comment would be that a set up and mattress removal service should be offered.
started great...slowly sank and now i feel like i am sleeping in a pothole. it went from good to worst really quick. not happy with this purchase but happy with costco policy. they are awesome.
I had the bed for 1 1/2 months, it served whatever expectation I have for this bed that's why we bought it. Me and my husband likes it a lot.
Sleep in this mattresses for one month. Good quality but just too firm for me.
I've been sleeping on this for about 2 weeks now, and I'm kicking myself for not buying sooner! Very cozy.View More Reviews
I purchased this bed 9 months ago and just turned it over to find mold all over the bottom of the mattress. It could only have come from the mattress because there isn't any mold anywhere else in my entire home. The company refuses to do anything about it saying it could be from an outside source. But how could the mold only be on the mattress and not even the box spring or anything else? I don't know how long there has been mold but there is a good amount so obviously a while. This has been making me sick and my allergies horrible. Last night was the first night without the mattress and I didn't wake up with a headache, my nose wasn't stopped up, and my throat didn't hurt. I feel disgusted that I have been sleeping on mold and that the company didn't care at all. I wish I never bought this mattress. These pictures show the mold with and without the mattress protector.
well i read so many reviews calling this mattress firm,i will tell you this,an 8 inch mattress goes to about 1 inch soon as you lay down on it,its like sleeping on the bottom of a crater,you feel like you need a step ladder to get out of bed,i am 6ft,200lbs,average build,it just engulfs me ,its like dropping a marble on a cotton ball,the marble has no support so drops til it reaches a bottom,my biggest fear now is when it engulfs me i will disappear from sight,help i been swallowed by my bed and i cant get out!!!
These are great mattress! This is the second one I purchased. I originally had a full size and then upgraded to a king size recently. I used the first mattress for two years at least and I am 140lbs and have no complaint, the mattress is still good and will be used in my guest room. The new king size is doing just fine.
Wow! I am impressed with this bed!
My husband and I have had a memory foam mattress that we purchased eight years ago from Sam's Club, and we have liked it, but we wanted to move from queen to king size. We shopped everywhere online trying to find the best bed for the lowest price. This is it.
Here are the things we experienced:
--NO smell at all. I am sensitive to smells and have asthma. Neither my husband nor I smelled anything. I put my face in the mattress right after opening. Nothing. Certipur is one feature I required, and I say it is valuable.
--Was expanded to 12 inches in less than an hour after unpacking. (Indoor air temp. about 75F. Outdoor about 87F that day.)
--Soft top half, feels like a pillow topper but with support underneath.
--Warm and cozy -- we will save on heating in the winter.
--NO stiffness in our bodies, noticeably no pain in the morning. This shocked us; we thought all memory foam would do that and that any soreness we had was just us getting older. Nope. This bed made a difference in our bodies.
My husband likes firm; I require soft. I am pear shaped and a back and side sleeper, and a firm mattress arches my back and hurts my tailbone, hips, and lower back. I have to have something that lets my booty/hips sink. My husband has scoliosis and lots of back pain and needs support. He is also a belly sleeper and needs support for that as well. We are both VERY happy with our sleep experience! I don't know how this is possible, but I guess it's the "Sleep Master" experience and the beauty of memory foam.
It arrived on time, in a box about four feet tall and wrapped in two layers of compression materials.
Here is our setup after removing the cardboard box:
We set up the box springs (two Twin XL) and frame. My husband handled the mattress by himself, unboxing it, pushing the rolled mattress down the hall, lifting it onto the box springs.
The instructions were simple and clear. We removed the first layer of packaging (which was a white plastic tarp-like material with reinforcement), positioned the mattress (still compressed in a second layer of clear plastic) in the center of the box springs and realized it was folded in half with the wrong side up. At that point, my husband and I had to lift the folded half to position it correctly with the zipper side down, and this was the most awkward part. Once in place, we removed the second layer of compression material. Magic! It started decompressing and was a full 12 inches in less than an hour.
I can recommend this mattress with confidence. We're happy, more-than-satisfied, and well-rested.
I chose this particular model for several reasons. First, it is manufactured by Zinus. Now, Zinus does not have the name recognition of Tempur-Pedic, nor the same high-end reputation, or prices. Various Amazon sellers sell at on of assorted Zinus mattresses under a bunch of names, and they mostly get very good reviews. This model, a 10" Queen featuring 3 inches of memorey foam over "2 inches Pressure Relieving Comfort Foam," on top of 5 inches of higher-density base foam, appears to be identical to other brands that receive 4+ star ratings over numerous sales here. Add to this the fact that this particular listing was both shipped by and sold by Amazon, and I felt I couldn't go wrong. And, of course, my innerspring mattress was 15 years old and needed to replaced.
I received the mattress only today, and have only slept on it for a few hours, and will update this after a few weeks and maybe later. Prime 2-day shipping didn't fail me, and the 65 lb box was dropped right next to my house by FedEx. I handled the box fine myself but it was a little bigger than expected and without any handles, and a lot of people will definitely need help to move it up any stairs, if not move it all. Neatly packed, nothing extra, no cushioning needed.
Some reviews of memory foam mattresses led me to believe they can take 24-48 hours to fully expand from their compressed shipping state. Others caution you to have the mattress at least near where you will ultimately sleep on it before you unwrap it. The second bit of advice is defintiely worth mentioning; mine expanded and unfolded rapidly, reaching near-full dimensions in seconds. After wrestling it of the floor (I should have opened the plastic with it on the platform), I measured its height at 9 inches. Two hours later I found it a full 10 inches high. It is also a full 60 x 80, unlike many mattresses on Amazon that are undersized at 58 x 78 inches. That is a big deal to me - I want all of the 80 inch length a proper queen mattress provides, and filling out standard sheets without them being loose or baggy is a must.
I have not had a full night's sleep as of this review, but I did take a quick nap, which turned into a very long nap. It is comfortable. This mattress cradles me enough, yet is still firm enough to be supportive. Time will tell, but my initial impressions of this mattress are that it will be great to sleep on, and that it is a real bargain.
It is so darn comfortable that I don't want to get out of bed!! I seriously have no idea why I spent $1200 on my previous pillow top that was not even that comfortable to begin with when I could have been sleeping on memory foam this whole time.
There was no chemical smell at all that I could smell. Within 2 hours it was puffed up to full height and ready to go. I was expecting a mattress that was really firm from some of the reviews on here but it really isn't. It is soft and as soon as you lie down the foam melts around your body. I don't think I have had this quality of sleep in a long time. I am a toss and turn kind of person but not on this bed.
For the price you absolutely cannot beat it. I would recommend this bed to anyone, especially people who sleep on their sides. That is how I sleep and usually in the morning I wake up and my hips are in so much pain, but no more!
Just as a testament to how comfy this bed is...my son decided to climb into my bed in the middle of the night the first night I bought it because he wanted to sleep on the new bed. Usually he is up at 5:30. He slept in until 7:30 and even then I had to wake him up! I think I am going to buy one for his bed as well!
Great mattress, true 10" and no smell as other reviews claim to have... Medium firm awesome I let it breath for 8 hrs and perfect, it was ready to go within 2 hrs.
Buy with confidence you won't regret it.
My fiance and I have been using this mattress for a year now with no troubles. For reference, I weigh 130lbs and he weighs 330lbs, so you'd expect some sagging on his side, but we haven't noticed any yet. It's comfortable enough for a good night's sleep, although if I have a cat sitting on me, the uneven weight makes my hips dig into the mattress. For the price, this is as good as it's going to get. Highly recommend if you're looking for an inexpensive bed.
The most comfortable mattress I have ever laid on!!!! Buy it - do not hesitate. Worth every penny and more!!! Small chemical odor but I assume that will go away with time. Super thick. Medium firm.
This is a VERY NICE mattress and a wonderful addition to our guest room. It arrived as promised when the mail carrier drug it across our driveway and left it about 25' from the truck. The box was "solid" and felt much heavier than the 48 pounds the scales said. We used a hand truck to carry in into the bedroom. Having seen the warnings, I carefully opened the ends only to find what looked like a stuffed laundry bag. At first I tried to slip the bag off it but there was too much tension. So I took scissors and carefully slid them between the plastic mattress cover and the cloth bag. As I did it literally popped open on the box springs wrapped in a heavy plastic cover. After taking that off we opened it for the two day "airing out" period that was recommended. There was a mild odor at first that was gone by the second day.
The white cover was opaque so I couldn't tell for sure which side was the top (hint: the zipper goes down). We bought it for the guest room, but slept on it the first night. We didn't want something in there that we wouldn't like. It was EXTREMELY comfortable, and much more comfortable than mattresses costing double or triple the price that we tried. It is not a soft mattress, yet not too firm, but has a comfort that gave us a good night's sleep. The only difference either of us could tell with or without the bed board was that the sides didn't sink down as much with it -- so we left the bed board under the mattress. I suspect it would be almost as comfortable just placed on a floor without any springs.
One VERY MINOR "problem:" It is slightly larger than the box springs. As advertised, after it opened, it was 75x54x8. Full size box springs are 74x53. The 2" extra width is not a major problem and, as shown, is hardly noticeable. It does somewhat affect how much the side squishes down when you sit on the edge of the bed. The bed we put it on has both a headboard and foot board so the 1' extra length is not even noticeable.
I'm glad we purchased this mattress. It is a welcome addition and upgrade to the very old set we just removed from the bed and something our guests are sure to enjoy.
*** I did NOT receive this product in exchange for my review. I am not cool enough for that. ***
I ordered this mattress for my son, who specifically wanted a "mattress I sink into" to replace his aging Sealy "twin mattress that you give to your 8 year old because it was on the bottom trundle of someone's daybed for a decade and was slept on maybe twice but it's from a time when mattresses were FIRM like John Wayne's resolve!"
I did a ton of research. This product has nearly identical branding to three other mattresses on Amazon - identical documentation, identical "composition diagrams", everything. But it's $50 more. Why the price discrepancy? Because apparently Zinus is a real company that actually honors warranties. At least that's what I hear.
As everyone else indicates, this shows up in a duffel bag. The instructions are flat out wrong - it shows up folded in half and upside-down before being rolled up. You have to unroll it, unfold it, THEN flip it over, THEN cut the bag off. The only good news is that since I only bought the "full" it wasn't all that heavy. Then again, I'm a big guy. If you are a teenager or slender woman I would imagine this is not something you'd want to move all by yourself.
Once it's unfolded and inflated (which took about 24 hours to reach full firmness and regain its shape) it is a mattress sized (and shaped) chunk of memory foam so moving it around is unwieldy, but no more so than an actual mattress.
It is EXACTLY full-sized. And it is PERFECTLY rectangular. Just like the picture. It fits snugly (but not so snugly that we couldn't get a mattress pad and sheets on it) into the full-sized platform bed from IKEA that my son sleeps on.
When first inflated (for the first 24 hours) sitting up on the edge of the bed resulted in instantly crushing the entire mattress. The first time I climbed onto it, my knee touched bottom. That all changed within the next 24 hours. It is now firm, and even with my son sitting on me my hips don't bottom out. I'm sure I'm touching the support foam, but that's it. Sitting up in bed now results in a good amount of mattress supporting my butt. And I'm not light.
The included cover is decent - and zippered for removal so washing will be easy.
Now, the good part.
It's memory foam. In a 10" mattress. I took the zipper off and it indeed looks as intended - several inches of memory foam (hard to say if there's really a "comfort foam layer" or if it's just more of the same memory foam, as it's the same color) and several more of support foam.
It's REALLY comfy. As in "lie down and you don't have to toss and turn or adjust yourself or even really use a pillow because OMG it's comfy" comfy.
It retains its shape, it doesn't seem overly hot (it is supposed to be a cooler type of foam, after all) and it seems to be exactly as promised.
I will update this if that ever changes. And I might just have to buy one for my own bed, I'll be doing a sleep test this weekend!
All my roommates sat on this, and they each want one now. One even said it's like sleeping on a marshmallow. It came very nicely packaged. I had no problem opening it and airing it out for about 30 minutes. Description said it may have a natural foam odor, but I didn't even notice. Had it half a year and I've been able to sleep easier and longer.
Like many folks here, I bought this for my son (9 yo). Came vacuum packed, which is cool. My wife unpacked it and I carried it upstairs (she could've but that's how I roll). Real comfortable, especially for a kid. At 225 (think lean muscle and smoldering good looks) when I sit on the bed my butt does bottom out on the boxspring a bit, but once you distribute your weight you are going to feel like Han Solo frozen in carbonite (except you will be smiling).
I've been sleeping like a baby since switching to this mattress. Very pleased. It took approximately an hour for mattress to fully expand; left it on top of the pool table for a few days prior to moving it to the bed. Purchased the full size. Love that you cannot feel your spouse moving during the night. Will eventually change all of the mattresses in the house to this Ultima memory foam.
It's a bit taller than I expected (don't know why, it's as thick as the description states). Fits the space in our 5th wheel perfectly, much better than the crappy standard queen size bed the previous owners included. Just the right amount of tossing and turning at night (this is more important than you think, if the bed is so comfortable you don't move at all during the night you'll hurt quite a bit in the morning...this explains many "felt great the first couple weeks but then I got really bad back pain and had to throw it out" reviews that some mattresses get).
It's honestly one of the most comfortable mattresses we've had. Easily worth twice the price (though I wouldn't have paid that much). And the short queen wasn't much more than a regular queen, which made it an even better buy (short queen mattresses, common in RVs, generally cost much more than the larger standard queen, and quality often leaves much to be desired).
Please know I'm a Tempurpedic lover - I had the Cloud and also the Grand Bed. I bought this to sleep on every night because it's all that fits in a tiny room. I was hesitant because some said its not good for daily use, others said it smelled, some said it was cheap. I've slept on it 4 nights now and it's AWESOME. There was no smell at all (even when I opened it), I DID wait 24 hours for it to fully puff up before sleeping on it. I sleep on my side and I swear it's more comfortable than my old Tempurpedic. Laying on my back to watch tv is fine too. I wouldn't call it firm or too soft, the memory foam is just right for me and I have had NO back pain. I'm a skeptic so I am shocked at how great this really is. Give it a shot and buy it!!
First I must say I thought they made a mistake when I received the mattress. It was delivered in a box, well not use to seeing a mattress all fold up in a box. Once I opened it and placed it on the bed again I thought they made a mistake. I got a tape and measured the width it was not 8 inches as ordered. Well it just took some time to open up to it's correct size. After a year I have no issues with the mattress and if you are use to the spring mattresses you can feel the difference with this sleep master. I am thinking of getting another mattress and it will most likely be the same one.
This mattress went from the best mattress we ever bought to the worst, most uncomfortable mattress we'd ever slept on in under a year. At first we raved about this mattress and recommended it to a few family members and friends. Thank god they bought different brands because this has turned out to be one of the worst investments we ever made. Last year the mattress was about $75 more expensive and we didn't have a huge budget so we got what we could afford at the time. But maybe 7 months later we started finding it uncomfortable and here we are 1 year and 3 months later and we have just purchased a new mattress to replace it.
Basically it just doesn't hold up. It has absolutely no support. It is lumpy and painful. We feel the bed frame or box spring (we tried it with both) underneath when we sit down. At night when I roll over I feel my hips hit the box spring below at this point. Both my husband and I are miserable on it and have had back aches for the past few weeks.
Do not waste your money.
I was definitely leery about buying a mattress online. I went to Sam's Club, Mattress Warehouse, Bedding Barn, yadda yadda, and tried a million different mattresses. All of them were lovely, but none of them were cheap. Is this bed stellar? I wouldn't call it that. But it is a wonderful bed for someone who really doesn't want to spend much more than 200$ on a mattress, and someone who certainly doesn't want to try to haul a huge ass mattress on the top of her little Ford Fiesta.
3. Cheap. Seriously, where the hell else are you gonna get a decent mattress for this price?
4. It comes to your house in a box. You open the box, open a bunch of bags, and the mattress gloriously unfolds for you. After having moved sofas and tables and desks and lamps into my apartment, it was MAGICAL to have something normally so bulky arrive and take pretty much zero work to set up.
5. It's a good mattress. I've had it for almost a month now, I sleep well, there's no noticeable comfort issues. Many of the negative reviews I read mentioned that it was too firm, firmer than they were expecting. I think that's because when people think memory foam, they think Temperpedic. See the con section below for more on that, but given all of the complaints about the firmness I was pleasantly surprised with the softness of it. It's firmer than I like, but it does kind of contour to your body. Also, unlike Temperpedic, this mattress doesn't trap all of your body heat! I hate waking up sweaty so this was a huge plus.
1. Smallest con ever: it smells funny for like, 10 minutes after you get it. Really not a big deal though.
2. Do not expect this mattress to be a Temperpedic. If you've done any research on mattresses, you'll know that cheaper memory foam mattresses use a cheaper, different density foam than the fancy ass Temperpedics. (If you haven't done research yet, I suggest the Sleep Like the Dead website.) The skinny on these mattresses is that they run firm. And yes, this bed is firmer than I prefer. But see the PRO section above for why this doesn't matter to me that much.
3. Now I don't know this first hand, but I have heard that there's really not much you can expect in the way of customer service from this company. And honestly, if you order a bed-in-a-box like this, open it and find out 2 weeks later you really don't like it, what are you going to do? You can't ship it back, because there's no way you can squeeze the mattress back into the box. So I'd suggest trying out a bunch of mattresses, making sure that you're okay with something like this, I would say softer than a firm pillowtop, but firmer than a high density memory foam mattress like Temperpedic. Be REALLY sure you want to buy this before you place an order.
ALL IN ALL - This is a good, budget mattress. Generally speaking with mattresses you get what you pay for, but I would say this is a really good deal.
Perhaps this review will help you.....
Details: I am 5'10", 268 pounds, stocky, and was recently not-exactly-diagnosed with sleep apnea. My doctor believes I may have this issue, but without tests, hard to confirm. I had bought a Serta Plush Firm mattress that basically just got flat on top and was left with firm.
So, my review of this mattress is based upon the following:
1) Ease of assembly/setting up: The box they put this in was not exactly super heavy but was awkward to move around. Once I got it out of the box and on the frame it was super simple to set up. Remember: The zippered side goes on the bottom!
2) Inflating: I received the mattress around 2:15 in the afternoon and had on the frame by 2:40 (note: That is only 25 minutes). It was fully inflated in just a few hours and I slept on it that night. If you get the mattress and it arrives after 7PM, let it inflate and sleep on it the next night.
3) Smell: Unlike others I did not have any type of overpowering smell. It just smelled "new." TIP: If you think you may be bothered by the new smell, run your sheets through the washer and use some Snuggle concentrated fabric softener. It's got a great smell and will counteract any "new" smell of the mattress.
4) Firmness: When you first crawl onto the bed it feels a little firm, but then you sink into it and it really does conform to your body. I always lay on my back and watch some TV when I first get into bed at night. The first night I turned the TV off and laid to my left side. I felt the mattress firming back up to conform to my body.
5) Adjusting: With my old mattress I had to toss and turn several times before I finally got to sleep. I ordered this mattress on Halloween and it arrived 2 days later thanks to Prime. Every night since (over three weeks now) I got this mattress I roll over after turning the TV off and I am asleep within 5 minutes! I have not had to toss and turn any night since to get comfortable and fall asleep.
6) Other: With my old mattress during the day I was constantly having to turn my body to try and "pop" the bones around my lumbar area. I'm not doing any of that any more. Also, I would wake up previously and have to stretch my legs and they would just pop from no getting good support. They are not doing that any longer, either.
7) One person said you may not need a pillow and I think another said you will not need two pillows. I am not so sure about the no-pillow option but two will definitely not be needed. I bought a memory foam pillow a few months ago at Belk. It was an Isotonic something or other, and it has relieved all of my neck pain. It was the precursor to getting a memory foam mattress.
8) Heat: I have not had one problem with heat, and I am hot natured. I have bamboo/rayon sheets and they are very breathable and soft. I have an alternative-down memory foam comforter on top of that. I keep my house around 65 year round.
9) Overall: I would recommend this mattress to anyone who asked, and I would purchase again if I had to do all over again.
I hope this helps. Any questions? Feel free to comment and I'll be happy to answer!
10/18/2014 UPDATE: Almost one year later and I am still loving this mattress! The side I sleep on has held it's shape greatly. I am thinking about turning it around on Halloween (1-year- anniversary) to see how the other side compares since I have slept on the same side a whole year. As of today (10/18) the mattress is on sale for almost $100 off! You can't go wrong with this mattress. Also, about the heat: I dropped the bamboo sheets as they were crap! Going back to regular cotton sheets was a tad warmer, so just lower your A/C at night and you'll be fine!
I am a chiropractor for 30 years. This is the best bed of all time and the best price on the internet. The bed completely conforms to your neck and body. You don't even need a pillow. I would do a commercial endorsement for free.
I went back and forth on buying this. I was raised with the "you get what you pay for" and "if something is too good to be true, it probably is" mentality. So when I saw this, for the price here, I was skeptical. The reviews were overwhelmingly good, but with my bad back, I was really wary about buying a bed without testing it out, buying a mattress for less than $300, and very concerned about how I was going to make do if it didn't work out. But, being on a budget, the choice became this or a donated futon mat... It didn't take long to make the choice after that.
The bed arrived in a box about 18" x 48" x 18". Looked a little bit like a cardboard coffin, actually. It came upstairs with little fuss (it was heavy, but not too bad), and we opened it up. The packaging was secure, and thick enough that I wasn't worried about cutting into the mattress. YOU DO HAVE TO BE CAREFUL IF YOU USE SCISSORS. There is a little room within the box, but not much.
We don't have a box spring yet, so the mattress went onto the floor directly. Within minutes, it was fully puffed up, and so comfortable, I couldn't believe it. We added a thin bedspread to it for extra padding over the sheet, and that did the trick to balance out the lack of bed frame or box spring. The smell that people talk about was gone by the time the bed was done expanding, but I would recommend you open a window or leave the door open, or even turn on a fan, while it's doing its thing. If I'd left the room closed up, the smell could have been overwhelming.
So, the rundown:
* Great price
* Easy to set up
* Works with bad back
* Cushy, but not overly so
* Not too firm, just about right
* Even comfortable on the floor
* Smell, but not overwhelming and gone quickly
I was skeptical about this bed, so cheap. Let me tell you I have not slept better than this in the past 10 years. I work 2 jobs, and have chronic back pain (bulging disks). I wish I would have found this bed years ago.
Excellent mattress! I've had a tempurpedic for 10 years and it was time for a new mattress. I've had 10 spine surgeries and 7 spinal fusions and this mattress is amazing. No pressure points and you don't over heat like the older tempurpedics. A great deal!!!! Couldn't be happier
This product is not the same as a full size bed, It is much smaller. I have no Idea how to send this thing back?
Looks like it would be comfy but does me no good the way it is...
This is probably the most comfortable mattress that I've slept on. On our old mattress, I would go to sleep at 9:30pm and wake up at 5:45am. I figured this was a good schedule to me. After getting this new mattress, I've gone to sleep at 9:30pm but have woken up at 4:30am, having not moved at all. After that I toss and turn for another hour until it is time to get up because I'm already fully rested and don't need to sleep anymore.
For me, this mattress is not too firm nor too soft. For some, it may be too firm, as this "memory foam" is not the same stuff as the higher end brands. That is neither praise nor critique. Whatever the foam is (3 different layers of different foam), I'm loving it.
I searched for a while and could find no videos on this mattress so I posted one on youtube. You can find it by searching "Sleep Master 12-Inch Pressure Relief Memory Foam Mattress" and look for the video with the thumbnail reading "Sleep Master Mattress Unboxing".
It's been a long time and this mattress remains in the same condition as when I bought it. It hasn't lost any of the characteristics I've been loving throughout these years.
I've been sleeping on it on a daily basis with not a single minute of regretting.
6' tall, 260lbs, and sleeping really well, I have not experienced temperature problems, loss of firmness, deformation, or any other so far, so I thought it would maybe be of help to others to do this update.
My original review (below) stands after all this time, and I still recommend this product.
I find this to be a great product.
As my bones have grown older and my joints crankier I've tried several different mattresses, some better than others, some pricier than others, but for the first time I can say this is simply the best one I've slept on so far.
It is soft enough while firm enough as to provide great comfort to a person like me, with joint-related issues. I can sleep all night without having to wake up to move for a while and without more tossing and turning. I wake up in the morning fully rested, with no pain or discomfort whatsoever.
In my case, I did not experience the problem of strong chemical odor other reviewers have referred to, the mattress expanded really fast and evenly, and after a fairly long trial period I am completely satisfied with the product.
I will not say it may be the best mattress out there, but it is the best of the many I've tried, and the price is excellent.
I will keep it.
Great product. Highly recommended.
I will start by saying that it is VERY rare that I would take time out of my schedule (even 15 minutes) to write a review. This mattress however deserves a positive review of more than 5 stars if that were an option. I currently own one of the original foam Tempurpedic mattresses. It is 10 years old and still in great condition. My situation is that I have recently had a major back surgery. A fusion from L4 L5 S1. With being off from work during my recovery, I have taken on a temporary roommate to assist with bills and mortgage. I moved from my master bedroom to my spare bedroom to accommodate my roommate whom I need more than she needs me. Anyway, the smaller bedroom would not accommodate my queen size bedroom set so I chose to put a twin size bed in my room. I then had to find a preferably foam mattress for a twin bed. I read many reviews on foam mattresses and compared pricing on multiple sites. Trust that I have done this research for you and you need not look any further! I am a flight attendant and I can say that I have slept on hundreds of beds across the United States and beyond. This mattress is amazing and comparable to my queen size Foam Tempurpedic that cost a couple thousand dollars! I am still healing from my fusion surgery and I am so impressed with this bed's ability to conform to my body. As a curvy women, the bed gives where it needs to. I don't feel as though I sink down into it. It is soft yet supportive. I have invited friends and coworkers to sit and lay down on this bed and they have all been very impressed also! A couple have already stated that they will purchase this mattress themselves. When I require a new foam mattress or if I decide to upgrade to a king size bedroom set, this will be my mattress of choice! Do not waste your time or money on any other mattress besides this one!
I bought this mattress to replace my 12+ year old memory foam that was 8 inches in depth and has served us very well. It too was an online purchase in an effort to have the comfort of a memory foam and not the expense of a Temper Pedic. We just took off the old mattress, unwrapped the new mattress and put it on our bed. Within 5 minutes the thing had already expanded to it's full 12 inch height and completely filled our California King bed frame. I took the liberty of falling down on it just for a dry run through since I know we need to let it set for approx 24 to 48 hours for it's full expansion. Gosh, it was like falling into a cloud. My husband and I are in that middle age spread thing with plenty of arthritic joints to go around and this mattress should fit the bill of supporting all those achy spots the old mattress had stopped supporting.
I read other reviews that mentioned the bed was hard, but ours couldn't be softer. Another mentioned that they repeatedly got defective, lumpy mattresses, ours was perfect first time out of the box. It is in fact, softer than our previous memory foam and there was little or no odor coming out of the plastic wrap. I am genuinely tickled pink with this purchase and look forward to sleeping like the dead on it. What an awesome buy for the money and can't recommend it enough!
Great bed. Very quiet. No issues with springs or creaky wood box spring. Only critism would be that the foam holds heat. I purchased mine when it was still warm and I have been waking up sometimes in the middle of the night sweating. Hopefully it will be the opposite in the winter time.
I bought this mattress for my apartment in the beginning of January based on the overall good reviews. One month later I regret it.
Shipping & Delivery -
The mattress came in just over a week (without prime shipping) and was packaged in a box that I was able to easily take from the storage area of my apartment up the elevator and through the doors that led up to my room. I was also able to quickly and easily unpack the mattress and let it air out to its complete 8" size.
Mattress Quality (first 2-3 weeks) -
For the first 2-3 weeks of owning this bed it was great! My sleep quality considerably improved from my old mattress and the memory foam retained its shape and supported my body throughout the night.
Mattress Quality (1 month in to present) -
Around the 1 month mark I started to have back pain and began to pay attention to how the bed felt as I got into it each night and what it looked like once I woke up in the morning. The mattress had begun to lose a lot of its shape and the memory foam was supporting my body less. Instead, I was just sinking into the mattress and it was no longer providing the support I needed.
Overall you get what you pay for - a bargain price for a cheap memory foam mattress.
This 8 inch memory foam mattress is working well on a foldable frame, without a box spring. I like memory foam, and I found it comfortable. It does "dent" for a while after using it, but does return to original size within a few minutes. True to size, sheets fit well. Would buy this again if the need arises.
Bought three Twin Sleep Master 8" Memory Foam Mattresses. They arrived on time and after letting them expand for a couple hours they were ready to use. They don't have any worse odor then any other foam mattresses we've had and it goes away after awhile. They're pretty firm and perfect for my kid's bunk beds. The kids are satisfied and that makes me satisfied!
better than I expected ..great buy for the price bed is comfy not too hard not to soft just right
This bed is soooo amazing!! I was skeptical about buying a bed online especially after reading a lot of mixed reviews but I was pleasantly surprised. This is the best purchase I have ever made. The mattress is soft yet also firm and it conforms to your body. It did not have a smell and expanded fully after a few hours. It's like sleeping on a cloud and it does not get hot. It is actually pretty cool, I would have to confirm in the summer time though. I also bought two 8 inch twin beds and my kids love it. I just hope that it lasts at least 5 to 8 years. If it does it is definitely worth the money versus buying those expensive mattresses in the stores.
We let the mattress expand on the bed frame (right on the wooden slats) and it filled in.....even though the size of the bed is different than a full size it didn't matter! It is extremely comfortable! I'm so happy that I didn't spend the money on a 3/4 mattress.
First off, I bought this product in the twin size a month ago for a spare bedroom loft. I was pleased with the product. It is delivered compressed, and when it was unpacked, it sprung to life very quickly and evenly. Because I was pleased with it, I ordered a queen for the same spare bedroom. This was a completely different experience. After unpacking it, I was surprised how uneven it appeared, but since it had been compressed and I knew the instructions said to wait 48 hours, I didn't worry about it. Now 48 hours later, this is a mess. There are parts that are very nice, but there are edges that haven't risen back up, and sections of the mattress that are inches lower the the higher points. If you would run your hand down it, it would be a lump after the other.
I would not recommend this because of the second experience.
Now that's an AWESOME bed! We've been building up our camper trailer for a year now and finally got to install the bed. This last weekend we got to try it out and see about any changes needing made. The mattress is sitting right on the board over the bed frame. I was really cool unpacking it and seeing it "inflate", we let it set in the trailer for 2 days, as I cleaned out all of my tools, and scrubbed the trailer to get lived in for a weekend. My bride kept saying "You're gonna love this" but I was dirty from all the work and didn't want to try it out and mess it up.
In our house, we have a king sized pillow top that is pretty good, but I have been still waking up stiff. After two nights on this one, I'm simply amazed that I'm waking up rested again. I have knee, back, and neck injuries from my military service, so living with pain is normal. The wife may have to order a king sized just to keep me sleeping in the house!
BTW, we have the 8 inch thick mattress and it's actually more like 10 inches. I'm 180lbs and I can feel myself sink into this one a couple of inches. Not one pressure point. Don't even consider the thinner ones, the 8 inch is it!
I bought this March and it is now mid-May. It is firm like others have said, but for me that works because I've always had firm mattresses. It does stain easily but I scrubbed it a little and it came out easily. Nothing sunken in parts yet, I'm about 110lb on my fat days and I sleep on one side consistently. It does what it's supposed to do. I also didn't let it inflate for 3 days like it says...I got tired of sleeping on a blankets on the floor so I decided to just sleep on it after like one or two days. I got the queen sized, 8in which is great. I probably wouldn't go thinner than that. SO is 160lb and when he sleeps over he has no problems either. The smell faded away quickly and I also grew to kind of like it (associating it with bed and being happy versus the disparity and depression that consumes my life). I used a mattress cover to remedy the stain thingy. IDK, I think it's a good purchase if you're at that awkward time in your life where you don't want to spend $800 on a mattress but want something comfortable for a few years.
