Some are very happy with these mattresses., but other folks have had different experiences. Overall, these mattresses are rated well, but with some caveats. Learn more below on the specifics.
A supportive mattress that properly cradles the body is what you need for a better night's sleep. If your bed doesn't support you, a mattress that does better would mean a much deeper sleep for you. These mattresses have been rated above average in support, but some had issues with how they felt for them.
Most reviewers find these mattresses to have fine edge support, which is well regarded by those that like to roll over to the side of the mattress. There still may be some dipping for those that have larger body types.
Having a mattress that is great for durability can save you thousands. Unfortunately, nowadays everything from what you wear to where you sleep degrades faster. These mattresses get mixed reviews from customers on durability. Each mattress is different in how it affects you individually and may feel comfortable for you for years, but others have reported not being so lucky. Make sure to take look at some of the customer reviews to see if the mattress should work for you before purchasing.
Wife is sleeping well on new mattress.View More Reviews
Love a firm mattress and this one is PERFECT!!!!!
This truly is the Best Mattress Ever! I got the soft mattress for my 12 year old son, and he is in love with his new bed! He told me it feels like sleeping on a cloud. Thanks for an amazing product at a great price. You guys rock!
Very comfortable, stays cool, good thickness, super supportive, and a great price. We love it.
that we bought for our bedroom so much so that we got rid of our sealy posturepedic and bought another king for a guest bedroom, We will be doing the same for the other guest room with a queen size. Nice that they give you sheets and pillows with the purchase also.
Amazing mattress The medium firmness is more firm then expected but I rather enjoy it.
We had a great experience through the whole process. Marcell and the rest of the staff are very knowledgeable and helpful. We were very happy with our purchase!
It definitely is the #bestmattressever! I purchased the medium firm one in Queen. It does feel like it isn’t all that firm at first but after a few hours it worked out. I don’t wake up with pain in my back and hips anymore and I finally achieved the restfulness feeling I was looking for. Goodbye dingy old mattress!
I shopped around for a mattress that was non-toxic and didn't break the bank. I finally decided on Brooklyn Bedding. I love my mattress! I'm a side sleeper and I chose the medium firmness level. The ordering process was easy and the mattress was delivered quickly. One thing I will note is that the mattress did have an odor which dissipated in about 10 days. I recommend it!
I spent a long time looking for a new mattress and decided on Brooklyn Bedding and I am grad I did. Customer Service replied very quickly to answer all my questions. I decided on med/firm and it is a little firmer then I thought, but it has been only 3 weeks so I feel it is getting softer.The quality of the mattress is excellent for the price and feels great. My wife and I are sleeping a lot better now then we slept on our old spring mattress. We don't get that 'stuck in the bed feeling', you sink in but not to much so it's very easy to move around. We definitely enjoy sleeping on this bed so far. They use new foam layers now not latex so hopefully it holds up.Thanks Brooklyn Bed for a great mattress.
Very comfortable mattress. Skeptic about buying online but glad I did.
Great pricing- a good deal with free pillows and sheets. Fast delivery! Happy to see Brooklyn Bedding here in Phoenix. Support a local business and choose Brooklyn Bedding!
I love the mattress so far, no complaints.
Great product and great customer service. Truly a satisfying experience! I haven't had any back pain as a side sleeper on bb mattress for a month now. Thanks so much.
Seriously I don’t know how I slept on anything before this!!!! Thank you so much!
Excellent in every way.
Awesome mattress! I bought a king with medium firmness and it is absolutely perfect. I also got 2 shredded foam pillows and sheets. The pillows are really comfortable, not too firm and not too flat. My package arrived faster than expected and was easy to set up.
This item was never received
My wife & I are replacing a 10+ year old King Koil that has served us well, but is probably past it's useful life. And as we get older, a softer mattress seemed appealing. Seems the hottest trend in bedding these days is the mattress in a box concept. So, thought we'd give it a try. After a month or so of online research, I was amazed at all the new companies pushing these. They all seem to have good reviews, and the independent review sites also seem favorable to them. Where to start? First elimination was beds that did not offer different levels of firmness....took about half the field out right away. from there, I researched the company's themselves, to get a feel for them. Brooklyn took the lead by virtue of their time in the business, and the fact they are also the mfg'r, apparently making beds for other sellers. The price was also a factor, and Brooklyn was strong here too, along with the solid warranty. (To be fair, all the brands seems to back their beds very well.) Based on all this, we decided to try Brooklyn, with the King/Soft model. We went with soft based on other reviews indicating actual feel was firmer than the name might imply. Wife & I are also not large people, and wanted a softer feel. Order was placed, and the bed arrived about 5 days later. This is our first venture into non-traditional (coil) bedding, so we were a bit apprehensive at the sight of this rolled up thing we pulled out of the box (also got the pillows & sheet set, more on those later) We pushed it up the stairs, placed it on our old foundation (King Koil box spring from the old mattress), and began cutting plastic. Once it was free, we positioned it somewhat properly, and stood back & watched. Within minutes, it looked like a bed! Crazy! Overall quality of the inflated mattress was very nice, appeared to be well made. The handles on the side are handy for final positioning. We put on the included sheets, which were also of good quality, and covered the pillows, which are crazy heavy, btw. This was all in the middle of the day, so we figured on letting it completely fill with air through the rest of the day, so it would be ready to sleep on that night. So, how was it? I resisted writing a review the next morning, as I woke up quite thrilled with the experience. I think it truly was one of the best nights of sleep ever! The combination of softness & support is nearly perfect for us. Feels amazing as the soft top layer sinks in, and the underlying support takes hold. Feels very luxurious. Motion transfer is somewhere between spring & memory foam (our son has a memory foam), we found to be just fine. The new Titan foam does indeed sleep very cool, I think even more so than our old spring mattress. So, it's been almost 2 weeks now, and we both love the new mattress. We are 110% happy. The jury is still out on the pillows....they may just be a tad to "fat", but are otherwise very supportive, and also sleep cool. I may try to remove some stuffing, see if that helps. Otherwise, this is just an awesome bed, especially at the price point it is offered. Longevity is also a bit of an unknown, since this is a new material....hopefully it be comfortable for it's 10 year warranty. Since this is the only (foam) brand we've tried, can't really compare to anything else. But we can whole-heatedly recommend Brooklyn if you are considering a foam bed. For us, it is indeed the Bestmattressever!
We bought two twin xl #bestmattressever's in firm for adjustable bases for my husband and I about 18mos ago. We had a sick dog so I never started sleeping on mine until July of 2017 because I was sleeping downstairs on a futon for the dog. After our dog passed, I started sleeping on the new Brooklyn Bedding mattress and was have terrible lower back pain. We suspected I didn't weigh enough for a firm mattress. I gave BB a call and explained what was going on and they suggested the soft or medium mattress based on my weight, height, and the fact I was a side/back sleeper. I was well outside their 120 return policy but they told me they would give me a % off a new soft or medium mattress! They are excellent to their customers!! I got a new soft mattress today and I have to say it is perfect!!!! I couldn't be happier and will forever be a Brooklyn Bedding customer because they care about their customers!
The best sleep I've ever had. I remember my first night. I was nervous. Opened the wrapper. Got the covers on and slid in. I barely remembered what happened next cus I slept so hard and deep that I almost called in the next day to sleep some more. The pillows are glorious. The sheets are so soft. I feel so supported by the mattress. Wish I would have made the purchase sooner.
So far, so good - very comfortable mattress!
The best night sleep I have ever had. Medium is perfect for me a side sleeper and my husband a stomach sleeper. I love the way you don’t fully sink in to the bed. It has a good bounce back to it!! Love love love this bed!
This bed is AMAZING!!!!
Fantastic mattress! I purchased a queen soft, because i am a side sleeper and need better comfiness. Received in about 4 days from purchase date which was great. There was only a little smell with it but by the end of the day it was subtle enough to sleep in. It truly unrolls and inhales air QUICKLY! so fun to watch =) This mattress is about 80lbs+ i am guessing, so for my 5'2" frame its a bear to move to the bedroom to set up. I LOVE plushness in my mattress so the feeling foam was not quite what i was originally hoping for but i think its great now (coming from a spring mattress). In spite of all that I still think I am going to go find a plush mattress topper to give it a little more of that amazing i-am-sleeping-on-a-cloud feeling. //side note, i received a deal on my mattress that included pillows and microfiber sheets. the pillows were WAY too firm so i took out some of the stuffing and its better. The sheets are not as incredible as they made it sound- not as cooling for sure- but they are decently comfortable, they are my back up pair now. Dont expect egyptian cotton but they are nice!
We have had the mattress about 3 weeks. We ordered the firm. Reason being, all beds soften up after about a month or 6 weeks and end up too soft. We wanted back support and we got it. The bed is very firm but is already softening up to perfect. Firm but there is still a comfort layer. We have tried other online companies and this is our favorite so far.
One of the best decisions I ever made !
Bed is great, still only a month old, but love it.
A guest who has this same mattress at home, was the first to sleep on this. She gives it 5 stars
Extremely comfortable. Back feels great
It is the first time in a long time we have not tossed and turned. We are certainly starting to feel a good nights rest.
Its definately firm. I'll give it 30 days, then decide how i like it. It does sleep cool & edge support is good
So far everyone that have slept on it in the guest room have liked it.
Wonderful bedding, price and service! Recommending to my family & friends.
Love this bed
love this mattress! both my wife and i prefer firm. This fits the bill perfectly. been almost 3 months now and we still do not have a furrow forming which is a good sign. I spent about a week trolling the internet finding out as much as i could about mattresses and checking reviews etc. And this is the one i ended up with. As an aside, we just went on vacation recently for 10 days - half way through we were both wishing we were home again just to get a good nights sleep!
Love it, shipped fast and straight up to my apartment and unwrapped and in position nn in less than 5 min. Very comfortable .
Have had it less than a month; but, so far so good. I'm sleeping well on it.
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.
I had the same mattress in queen. It was wonderful so I decided to buy the same in King and it is awful. The bigger size has no support in the middle. So the sides feels like the queen, but the middle sag tremendously and therefore gives no support at all. After 2 years of back pain, I have finally enough money to buy a different one. This was so disappointing because I still have the queen and still love it.
For a mattress that is above the norm; The 10" pad is very supportive of a 260lb man. A Very dreamy firmness and this mattress is easy to lift the corners during making your sheet fit well. The overall weight is about -85-88-lbs, and ladies are able to shift the full mattress with easy. Upon receiving the purchase, the unit did not smell of any odd chemical fumes, and We just enjoy the best sleep and naps of our Year. . . . The value in a modern mattress is a good investment, and the quality will provide a good 15 years span to your resting world.
This was great at first. It was very firm which we loved. It slept a bit hot but we made adjustments and got a wool topper. But now 4 years later-I am waking up throughout the night with shoulder and hip pain. After some reading I find that memory foam can 'soften' and lose support. I am so annoyed that after 4 years my mattress is failing.
I bought this Mattress 2 weeks ago, it came on time but the mattress is not inflated to 10 inches. The cover is still have baggy and feel like missing layers
Bought this model from Costco a few years back. One big reason I chose this one was the design included firm(er) foam edges (that you can't feel), but they help the edges not just compress to nothing when you sit on the them - and it really works. Fast forward to last month, bought another of same model for guest room. While new cover is nicer, mattress is a little softer and... no more firm sides. ;( Yes, the description shows a drawing that shows it still has foam wedges along the edge, but the design has changed so they look smaller, and are definitely not effective. Sides compress down to almost unsittable level. Returned and will replace with (sadly) one that has more robust edge support. Guess Sleep Science figured out what the 'money' feature really was.
After years of suffering from a traditional mattress, I was ready to make a switch. It took a few weeks to get used to, but I'm so glad I bought this mattress. It is very comfortable!!
I bought this mattress a little over 2 years ago and it is the worst I've ever slept on. I have had back issues ever since, and thought it was due to the fact that I picked up playing golf right around the same time. After traveling for work over the past year and a half, I realized my back is always fine as long as I'm not sleeping in my own bed. A friend just told me Costco would take it back so I will be returning it ASAP.
I’ve been using this mattress for about 7 weeks. It seems to have a ridge in the middle, and it feels uneven to me. This is our third 10-inch Sleep Science mattress, and the first to feel uneven.
We have 3 Sleep Science mattresses now and love them. We sleep so sound and deep. We feel great in the morning
We've been sleeping, and I do mean sleeping, on this mattress for six weeks now. I was in physical therapy for my back when the therapist asked me, "Could it be you need a new mattress?" I came home, looked at our Sleep by Number and decided we did.
We purchased this bed over 6 months ago and I waited to do my review to see how it lasted over time. It was a bit firm for me (a side sleeper) but my husband liked it. We purchased a three inch foam topper a few weeks later and it really helped with my shoulder comfort. Between the topper and the mattress, I sleep so well!! We are very happy with our purchase, would recommend for someone who likes a firmer mattress.
We purchased this for my 6'5" son in college because he had the 3rd floor loft up a spiral staircase and we could not get anything up the stairs. This mattress comes condensed, in a box. We had no idea what a great mattress it was until we visited and stayed in his room and could sleep through all the FSU football weekend noise! Since then, we purchased mattresses for our two daughters and two more for our beach vacation rental condo. We have had 3 couples so far that rented our condo and actually ORDERED the mattress while they were still staying in the condo so that it would arrive at their house before they returned. That should tell you how good this mattress feels. It's firm, but not too firm. It gives great support. If this mattress only lasts 10 years, for the price, and the quality sleep we get, it's priceless! Come stay at our direct ocean, corner condo and try it out while you enjoy a New Smyrna Beach, Florida ....call it a "research trip"!
I ordered this mattress from Costco and before I had even received it, I had a letter from the company to thank me for the purchase and contact information should I have questions or problems with the mattress. I have been using now for a week and really like it. I am a side sleeper and this is perfect for me. I would not hesitate to order another when I need one!
This was the second Sleep Science 10" foam mattress we've bought and it is even better than the first one. (Usually memory foam mattresses outgas for a few days after being unpacked, but there was zero odor this time.) We bought it for our guest bedroom and we still have the six years old mattress in our master bedroom. The Sleep Science memory foam mattresses are the best value in memory foam for price and performance over several years. We miss our mattress dearly whenever we travel and sleep on hotel/motel beds. We are 100% satisfied with these Sleep Science memory foam mattresses and recommend them to everyone!
Had guests in for 10 days and they were delighted to have such a comfortable mattress to rest on while on vacation. The mattress was reported to "hug" their bodies and it appeared to have great recoil to it's original state after being vacated for a few minutes. Would suggest it for a guest room.
We bought this bed for our guest room, because we enjoyed the bed we had bought 2 years ago for our own bedroom. Sleep Science had a great mattress. Thank you Costco!
hypo allergy , firm mattress exactly the that I want , at same time soft enough to give me excellent sleep .
I already returned to costco. It is listed under firm and it was very soft and spongy. Its great if you like a very soft mattress
I knew I would get good quality beds at Costco. We bought queen plush & wanted 2nd bed to be firm. Very happy.
Early indications are this Sleep Science mattress is a good product. However, there is an important CAVEAT: Sleep Science memory foam mattresses must be supported with a solid base. I purchased a platform bed from Costco with the mattress. The bed had slats as support. I was told by a Sleep Science Rep that I would need a 1/2 inch thick piece of plywood to properly support the mattress. I had two bad choices: 1. Try to (re)box a 78 pound bed and return to Costco. 2. Buy the plywood, have it cut to fit, and, somehow get it home. I chose the plywood. What a hassle. While I recommend the Sleep Science mattress, I caution not to buy platform bed with slats to support it.
Bought this Queen Sleep Science from Costco in June 2015 for a summer home. Read all the reviews and thought it would work but it's just too, too hard. Cheaper guest bedroom mattress is more comfortable! Awake with pain every morning. Finally added a memory foam topper last year to make it bearable, but we're replacing it now - Year 3 (total sleep time slightly more than 12 months!).
Despite waiting a over a month, the corners of the mattress never filled out to be fully 'square'. Instead they round off and don't fill the mattress cover completely.
Even more than a year after ordering, our son still comments on how he loves this bed.
We weren't sure buying a bed online & in a box would work out for us, but we have been very happy with our new mattress. At first, it feels really firm, but then it gives way so that hips, shoulders, etc are cradled. I am amazed at how light the mattress is, too. When making the bed, it's super light when picking up the corners to tuck in the bottom sheet. I thought it would be really heavy, like other memory foam mattresses. Overall, we're very happy with our purchase.
The bed is the perfect firmness for my back. I am able to wake up without pain. Costco shopped it very quickly! Thank you!
I bought this mattress 5 years ago. I researched extensively to find a firm mattress and based on good review I bought this. People shouldn't review any mattress until they use it for at least a year. Many reviews here written are just after a week or few weeks. Most of the mattresses would feel nice when new. The real test starts after a year. We loved this mattress in the beginning. Perfect amount of firmness, edge support, no hot flashes etc. After a year it started to sag n sink. We're not even large people I was 135lbs and my husband was 160 lbs. I started to wake up feeling really hot and back started to hurt. In just 2 years this mattress was really uncomfortable and some how we tried to manage it with some toppers but nothing worked. Edge support is gone, foam is of very poor quality. It has actually caused me severe back pain. I do not recommend this mattress. This is the first product from costco that I really really hate.
We bought this mattress thinking it’s firm . Backache started after first sleep on it. Called Costco to return. Costco return good , mattress bad bad.
This is my third Sleep Science Mattress. 1st was a 13” Queen which I gave to friends after I had it 10years. I had to downsize. They still say it is the best mattress they have ever slept on. The 2nd was a twin which was better than other conventional mattresses but I went on to this 10” full size to get back the 3” wedge support all around and it is a much better mattress. I suffer from bone pain and with this mattress I do not have it. The only Con to these mattresses is that they are warm so if you live in a hot climate consider that. If you live where it is cold it will make it an extra plus. I will buy another when this one wears out which I don’t anticipate happening any time soon.
