Allswell is a mattress brand that launched in 2018 to take on the direct-to-consumer mattress industry and introduce some new innovations. They offer four mattresses: the Allswell, Allswell Luxe, the Allswell Supreme, and their new, firm Allswell Brick. Each mattress features the adaptive and supportive benefit of pocketed coils with layers of foam above for pressure relief. For those on a hunt for a bargain, Allswell's mattresses are definitely a brand to consider.
Sleep Science builds a line of latex and memory foam mattresses. Their claim to fame is their 'wedge' technology that provides edge support to every piece of the mattress. Additionally, they are Certipur certified, which means they have low VOC and no formaldehyde in their mattresses. They also use bamboo material in some of their mattresses. Their mattresses are made popular through their relationship with Costco warehouse stores where they are sold at a competitive price vs many of the retail sold mattresses of similar material quality.

Super soft compared to my current mattress, yet firm enough to allow you to get back up and not hurt your back.View More Reviews
Very comfortable. Just RIght: not too soft so that you sink in, not too firm -- perfect. Very relaxing and feels so natural for any resting position -- whether you prefer to sleep on your back, your side or your stomach. Love it! Also, love the fact that they can get rid of my old mattress when new one is delivered. The fact that you don't have to have box Springs if you don't want to is nice as well.
BEST. MATTRESS. EVER. Absolutely divine for side-sleepers like me.Once I tried it, I couldn't go back to the one I have at home. Two very enthusiastic thumbs up!
It is soft yet has the right amount of support that I desire
I didn't want to get up ! This mattress is so soft yet supportive feels like I'm sleeping on clouds
I really like how soft this mattress is. I could sleep on this forever.
This mattress is absolutely amazing! It feels like you're laying on a cloud. I fell asleep with in 15 minutes of laying on it. Definitely recommend!
Usually not a fan but this soft mattress is wonderful!
I'm usually a firmer bed person, but this feels so supportive and comfortable. It's got really nice memory foam that doesn't sink in too much but feels really supportive while laying down.
My Allswell is a dream come true! When I lay down at night with my fiancé I instantly fall asleep, stay asleep and have the best dreams. Its comfy, cozy & cool. We are both very satisfied!
The most luxurious cumulus cloud does not hold a candle to my Allswell mattress.
But seriously, its the best sleep I've gotten since I was a kid.
Allswell team stopped by the office and immediately fell in love with the bed. Purchased right away! Cannot wait to have so much better sleep.
I was surprised how nice the mattress was! I feel like I will sleep so much better with it! So excited!
I tried out both the firmer and softer mattresses at a showroom and preferred the softer one because it was still firm but had some give, which made it supportive but also molded to my shape well. I was very impressed with the mattress and could see a couple sleeping great on it.
This mattress is so much better than casper. We just finished a trial with Casper and are so much happier with allswell.
The quality and feel of this mattress makes this price point an absolutely steal. The memory foam is just right and contours to my body. This would be a great bed for people used to sleeping on their sides.
Very soft, great material, you sink right in
This mattress is amazing because you can just sink in and feel surrounded by comfort. I love the feel and how the memory foam contours. I feel like you get a lot of value from this mattress and would provide an amazing night's sleep.
Loved testing this mattress. It's so soft, yet firm enough to provide the support I need to get a good night sleep. Would love to sleep on this every night!
I tested this mattress and it was nice and soft on top with a lot of give. I have a memory foam mattress topper at home but with this mattress I wouldn't need it! I will definitely consider this mattress when I move next since it's quite affordable.
This bed is perfect for someone who likes soft mattresses, but it also has firm overall support. It's super comfy and cloudlike without having a 'sinking' effect when you lay down. 100% would recommend.
I like to be obsessed with my bed. Not only do we spend so much time in them, but there is nothing better than weekend snuggles. Your bed should be something you love getting in every night, and hate leaving in the morning. This Allswell mattress is the perfect amount of snuggle// memory foam // and cradling. It supports your back, and at the same time, let's you sink in and feel snug. I am definitely going to have many great sleeps on this mattress!
The soft mattress is very comfortable and forms to my body. I am a side sleeper and it feels like it would provide me a very comfortable night sleep. I will definitely look into purchasing this mattress.
Very Comfortable and soft. Definitely something with coming back homend and sleeping on. Not extra bouncy which is good.
It's either my current mattress sucks or this mattress is too great. Comfortable, soft, and everything else you'd expect from a mattress.
The foam mattress is super soft and feels like you're laying in a cloud. It aligns with your spine so it would be very helpful for anyone with back issues. Overall great mattress!
The soft mattress not only feels durable, but has the right amount of softness to keep anyone happy. I feel this mattress would suffice for someone that has a soft or firm preferences. Feels more of a firm memory foam bed. Love it!
This mattress is incredibly comfortable and I liked it a lot. It was nice on my back and great for sleeping on my side.
Incredibly soft that molds to your body. Highly recommend
This mattress is one of the most comfortable mattresses I have ever had the pleasure of lying on. It is extremely soft and comfortable but not too soft that you no longer feel supported. It is the perfect mixture of comfort and support. I would fully recommend to anyone contemplating buying this mattress!
I typically don't like softer mattresses but this one has the right amount of support!
This mattress is quite soft, which is great for side sleepers like me. It doesn't give me too much pressure on my shoulders so my spine can keep straight. When sitting on the edge, it doesn't sink, which is important to me because I have a small bedroom and sit on my bed a lot.
This bed is so comfortable. It feels like I'm floating on a cloud. This bed is soft yet firm and I love it!
When I tried out this mattress, I knew I had to return my Purple mattress. The mattress is super comfortable without being too soft or too firm, and I feel supported by the mattress. Overall, it's fantastic, and I can remember wait for better sleep!
Laying down on this mattress simultaneously feels incredible while telling you all that's wrong with your current mattress. If you're looking for the perfect blend of comfortable and supportive, this is it!
I have been searching for a great side-sleeper bed and I have found it!
I'm usually skeptical about soft mattresses. I love the feel but you normally sink in too much. This Allswell soft mattress feels like I'm sleeping on a cloud yet still gives enough support for my back and legs. I love the construction of the mattress as well, double stitched and reinforced on the sides with a stretchy material on the gusset for durability. I feel like this mattress can last me awhile. This is so plush and wonderful to lay on and to sit up on when I'm dozing off or just waking up to catch the morning news.
This mattress is incredibly comfortable--feels like sleeping on a cloud and is great if you prefer a softer, less firm mattress. Definitely worth checking out and giving it a try! You rock, Allswell!
I've tried Casper, Leesa, and Brooklyn Bedding - and I've been trying tout find the mattress that will actually align my back. After trying out the Softer Allswellhome.com mattress, I think I, as have found what I'm looking for!
This has been my third mattress in adulthood and it is by far my favorite. I have upper back pain and I immediately felt myself still getting a good night's sleep even with the softer mattress. Before it'd always been a trade off between soft mattresses and a firm surface for my back, but with this mattress I get both.
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.
