Level Sleep is an all-foam mattress that features proprietary TriSupport technology that supports the spine using zoned support. The shoulders and hips are relieved of pressure, while the spine is supported by firmer foam. This is ideal for side and back sleepers with back pain and those that are concerned about posture. With data from an independent single-blind medical sleep study, Level Sleep significantly helps lead to more undisturbed sleep.
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.

Finding a brand that keeps its customers happy is a good first check mark for looking into if a mattress is right for you. Reviewers score these mattresses very highly versus others. Do some more research below to figure out if one of these mattresses are right for you.
Even support is extremely important for sleeping well, and these mattresses do a great job with supporting sleepers. Supportive mattresses don't always have to be firm mattresses. The important part of support is whether it supports a healthy spine. These mattresses are excellent at aligning the spine and providing that kind of support.
Do you want to sit on the side of your bed without the dip? These mattresses will provide a comfortable seated position on the sides of the mattress so you can take your time getting up or putting on socks or slippers.
Bowling Ball & Density Tests
Some reviewers use bowling balls to show the firmness of a mattress on its surface layer. Even support is one of the most important things to see during these tests. These mattresses are consistent with their firmness and support and react well to shoulders and hips.
Designing higher quality mattresses that last is a difficult issue for mattress brands. It means they have to invest in better product technology -- like foam and coils, and perform better in product tests. Also, it is difficult to measure at times because it is such an individual experience dependent on body weight and use. That said, these mattresses are rated exceedingly well on durability and based on the current information, should last a decade or more for most sleepers.

Reviews are an excellent way to get at the benefits of a mattress. That said, it is sometimes difficult to stay focused with all of the reviews from countless brands. Based on recent reviews and overall customer sentiment, these mattresses have some mixed emotions. Some sleepers are extremely comfortable, but others aren't as happy.
All sleepers need a supportive mattress and especially back and stomach sleepers. Side sleepers also need deeper support and a responsive mattress for their hips and shoulders. For most reviewers, these mattresses provide a good amount of support. That said, some folks didn't feel supported enough so if you are heavier, make sure to do extra research.
This mattress does well for most in terms of providing edge support. Over the long term, some had issues with dipping along the sides.
Mattresses don't last as long as they used to in years past. Finding a mattress that lasts over 15 years is hard to find. Yet, finding that diamond in the rough can save you lots of money. These mattresses get mixed feedback when it comes to durability. Some customers report no problems, but others have issues with the durability over a shorter horizon than average.
I had a bad shot mattress. I replaced with the tri support and have slept much better from night one. The mid support area is a little to close to the head for my baby. I have a twin. My abdominal part of my body is a litttle longer than normal and my legs area little short. I would have bought the longer and wider one but don,t have thes space.View More Reviews
The TrSupport Mattress is great! We wake up without back pain. It's just the right firmness and it's really fun to sleep on; raise your head, raise your feet and use the wave to relax awhile before sleeping. Thanks to the technology team for the development of Level Sleep mattress bed. This mattress is made with high grade materials and will last a long time. We may go back and buy the mattress TriSupport Topper for days we want a change of pace to pamper ourselves. We recommend this bed to anyone who wants to Sleep Happy. Thank you.
I really love this mattress, it is very supportive in all the right places. The staff are very helpful.
For years I have had to put a wad of socks under the middle of my back to give me the support I needed to lay on my back. With this mattress I no longer need to do that. I also had issues laying on my left side putting pressure on my hip and making it feel out of joint the next day. With this mattress I have a lot less of that issue as well. I am very pleased with the purchase.
We started sleeping on our luxe mattress 2 weeks ago and couldn't be happier! We previously had a different brand foam style mattress that cost quite a bit more and we are much happier with the Level Sleep product! Thank you JJ and Zach for the awesome service!
We upgraded to a king after having a queen, and couldn’t be happier! This mattress provides amazing back support! I had just gotten shoulder surgery, and as a side sleeper needed something super comfortable for my back - no pain, and love may be converted to back sleeping!
I love this mattress aND the pillow. I feel so much better in the morning when I get up. My neck is happy, my bow back is ready for the day. Three different firmness on the mattress support the different part of the spine. And the design of the pillow fits so well with the mattress. I'm recommending this brand to all of my patients now. And Zach, the sale's rep. he was o thorough, kind, step by step and he answered every single question that I had. (I ask lots of questions... :) so thank you. and I will reach out to Zach sometime next week to sign up the health professionals program for the clinic as well.
Thank you very much for your donation to my sleep following the loss of my home in the Sonoma Fires. I am grateful for your charity. The mattress has been great to sleep on. it was very easy to “install”! thanks again Isa Jacoby firstname.lastname@example.org
LOVE LOVE LOVE this mattress!!! Bought this for a new home in Prescott Arizona and couldn't be more ecstatic!!! Going to buy toppers for all others beds!!!
I have a very sensitive back and I cannot believe that the first night I slept on this mattress I had the best night sleep. It’s seriously the most comfortable mattress I’ve ever slept on! Thank you so much!
Thank you so much for your gift of support both emotional and physically. We are rebuilding our lives after the fire. Having a safe, comforting place to sleep at night has made a huge difference in our healing. Your team took such great care, showed so much kindness, and the mattress has actually helped with a lot of back pain that we were both experiencing previously. Much gratitude! Happy Thanksgiving, we are grateful to you! Kalika and Sean
the mattress isn’t much softer than i expected - but my back ache has gone and we have a restful nights sleep
This is the best mattress I have ever slept on!! Having lost everything in the recent Sonoma County Wildfires, we are so appreciative that you were able to help us. Thank you!
We are one of the many fire victims that assisted in getting a mattress. I can't say enough how much of a relief it was to have one less thing to worry about. Zach was the team member who helped me with our transaction and made everything even that much easier. They are super responsive, personable, and legitimately care about you as a person. The mattress itself is great. Provides support and is just right in firmness. You can't feel someone getting out of bed or rolling over at night wich also allows for the best possible sleep. Having a lot of sleepless nights, this was a very pleasant surprise. THANK YOU LEVEL SLEEP and thank you Zach. Very grateful.
Level Sleep was an incredibly thoughtful and most generous company to donate an amazing mattress for our son after the Northern California fire. We will certainly pass on the wonderful spirit of this company as well as the amazing products they develop at this local company. Thanks Level Sleep! Liz Takano
We have had our Level Sleep mattress now for one week and so far so good. It did take some nights (3) to get used to it and find the "sweet spot" for greatest comfort, but since then, we have slept great and have had no back trouble whatsoever!
I have had back and neck issues for quite sometime. I had no idea what I was missing out on until I slept on the tri-support bed! I am a Northern California fire survivor and the amazingly generous team at Level Sleep Sonoma gifted me a bed. I am forever grateful and will never go back to a standard mattress!!
I love how the mattress supports different parts of the body.
This mattress and pillows are worth every penny. Have been have great night sleep ever since. Should have bought this month's ago. Thank you for everything.
Before we purchased our mattress we had a couple questions about the product so we contacted the company to get more information. They responded right away and answered all the questions that we had. The were super friendly and informative. We purchased the king size mattress and have absolutely fell in love with it. My husband has back issues and this mattress has helped him tremendously! I recommend this bed to anyone looking to get an amazing nights sleep! It is totally worth the investment!
The mattress makes me feel like I'm being cradled in a marshmellow cloud. The support is just right for my girly hips. Really, really comfortable. I'm very pleased with this purchase.
Took a week off and went camping. I was nervous about being away from my mattress, so I bought the Level Sleep Topper to go into the RV. My back never missed a beat. Pain didn't even show its dirty little face. Usually by day three in the camper mattress, it is difficult to get out of bed. This time, woke up just like I do at home.
I'm so grateful my chiropractor suggested this mattress. For anyone who suffers with fibromyalgia, it is an answer to prayer. I also have a herniated disk & OA. This mattress provides the different levels of firmness/softness where they are needed most & I couldn't be happier.
I found Level Sleep through a friend and then was welcomed into their cozy Sonoma home store to one on for style. While the mattress in the store was amazing and is what prompted my first purchase for my new place; it was not until 30 days of incredible sleep that I appreciated the beauty of the TriSupport Mattress and Level Sleep's innovative technology. The stress of moving paired with other life altering events left me quite sleepless, but there was something in the comfort of my Level Sleep mattress that helped me sleep like a baby. More than 120 days in, my mattress continues to provide healing and restful sleep as promised. I am a believer! Thank you.
Recently bought a Level Sleep mattress when it was time to upgrade and we love it. My husband, who is an airline pilot, is sleeping better than ever. Just wish we'd bought them for every room!
I am always trying each night to feel where my body is touching the mattress, and I've normally dozed off without figuring it out. It's so cloud-esque that you can't feel it pushing up against you, you just melt in and then are supported. Loving it!
I am a chiropractor and my patients love the Restore Pillow. They are having better nights sleep on it and it also helps with their neck pain. The mattress is also amazing as well. I highly recommend. Dr. Cobb, Fredericksburg TX
The mattress provides great support and allows for a refreshing night's sleep. It's only been a week but so far so good!
Love the new mattress. It does what you said it would do - support the spine in the midsection and softer places for shoulders and hips.
We were long overdue for a new mattress and are very happy we chose a Level Sleep mattress and pillows. It arrived in a box that was easy to open and allowed for simple set up. We appreciate the different levels of firmness and find our sleep is more restful and in the morning it is easier to get out of bed!
I noticed less tossing & turning the first night I slept on my TriSupport mattress. After a few more nights, I realized I wasn't snoring as much if at all! I like it's firmness and that I don't sink into it but rather sleep on top of it. It's comfortable sleeping on my stomach as well, however, I find I do not wake up on my stomach anymore because I'm quite comfortable sleeping on my back or side. I'm very happy with my new mattress!
Level Sleep products are literally brilliant. They have varying levels of firmness within ONE mattress/mattress pad to properly support your body in different areas no matter how you sleep. My boyfriend prefers a firm mattress and I prefer softer - great, right?! Our mattress was TOO firm for me so we got the Level Sleep mattress topper and both LOVE it. He and I both agree it's the most comfortable bed we have ever slept on hands down. Years ago, we had a tempurpedic mattress which I actually loved but it trapped in heat which the boyfriend did not love and it was still not quite firm enough for his liking. Level Sleep products do NOT trap in heat and provide the perfect firmness in all the right places. Before getting this topper, I was having neck & back pain which has since gone away since I've been sleeping on this. I could not recommend Level Sleep products more. Worth every damn penny. We spend 1/3 of our lives sleeping - give yourself the gift of the frickin best possible most comfortable night's sleep (and naps) ever.
We got the mattress a week ago and have enjoyed every night of sleep since. Wonderful support, especially in the lumbar region, and very nice on the shoulders for side sleeping. The one thing that surprised me was the lack of support while sitting on the edge of the mattress. Not a complaint, just unexpected and took a little getting use to. The ordering process was very simple and delivery was quick. Getting the bed out of the packaging was easy as well, and very cool watching the compressed mattress come to life. I would recommend the mattress and company to anyone looking for a new mattress.
I bought a good mattress that was just too firm with no give. The Level Sleep Topper performed just as I had hoped. It truly does live up to what is advertised!
Incredible experience. Company treats customers with courteous, professionalism and above all the understanding of each individual needs. The mattress topper I bought is of high quality and craftsmanship and arrived at my front door, free shipping. Quick delivery, and as promised. I would definitely recommend this company to my family and friends.l
Best mattress for the back I ever had.
I had just bought a Casper mattress before being presented with the level sleep concept. So I ordered a cover. Incredible results. While Casper was decent, I now have enjoyed the deepest uninterrupted sleep in years !!! I highly recommend this product.
We bought this mattress based off our chiropractors recommendation d and we absolutely love it.
I have a chronic lower back pain so I tried several other options before Level Sleep. And I can surely say that Level Sleep totally works for me. This is the first mattress which really relieves the lower back pain. I feel better even throughout the day. Thank you! I didn’t think this was even possible.
My mattress topper is wonderful although it took almost a week to adjust to it. My aches and pains are not as bad. Thank you for making a great product.
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.
