I'm a chiropractor and I have been looking for an orthopedic mattress for myself, as well as something I can recommend to my patients. I've had the TriSupport Mattress now for almost 2 weeks, and I am very happy with it so far! It successfully supports the spine's curves and is comfortable in all sleeping positions. I have noticed an improvement in my sleep quality too (fall asleep faster & wake up feeling more rested than before), which is an awesome added bonus. Stellar customer service as well. Thank you!View More Reviews
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 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.
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!
The trisupport mattress is wonderful. The varied supports in the mattress lend itself for a painfree, relaxed sleep.
We were a bit apprehensive at first ordered 2 mattresses and couldn't be happier being a side sleeper my shoulders are in heaven sleeping better than ever Thanks
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!
we finally spent our first night in our new home on our sleep level bed. It was so comfortable. Jim said he felt very comfortable in all hia sleeping positions. I slept very soundly as well. I was going to send a note to thank the team for there great service.
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.
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.
After swapping out my expensive mattress for the much cheaper Level Sleep mattress, I wasn't too impressed, but after a few nights I started waking up without my normal back pain (from my L5/S1 fusion area) that I had become used too. Maybe I didn't align myself vertically in the right position, but I really became a believer and a huge fan on the Level Sleep technology as it is the best mattress I have ever found for alleviating back pain. Way to go team. Great Mattress and a Great price too!
I've been struggling with back pain for years. My chiropractor told me about this bed and What a difference! The bed is firm enough to sit upright in as well as support you while you sleep lying down. It does not move around or disturb your partner like many other beds. I used to wake up every morning so stiff and sore in my previous bed. The price is also extremely reasonable! The bed came in the mail and was easy to set up
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've been telling my friends about your intelligently made mattresses that we found to be very comfortable with support in the right areas. We've tried other mattresses that disappointed us rather quickly. We first put your mattress in the guest room and guests loved it, but then we decided to put it in our room and have been much happier than with our older, expensive yet sagging mattress. We recently stayed at Whitehall Hotel in Chicago that advertises as having the second most comfortable beds in a hotel....don't know what brand they use, but your LevelSleep is right up there if not better....
I am very happy with the level sleep mattress. I have struggled to find a mattress with the right support for my lower back that is also comfortable and good for the rest of my body. I appreciate this mattress has different firmness for different parts of the body. It seems to be working for me as I have been sleeping on level sleep mattress for three weeks and I have experienced good sleep and ZERO back pain. This is a welcome change from previous mattresses. On this particular mattress the sides are not as structured as ones I previously owned. I cannot sit on the edge without naturally sliding off the edge of mattress. Since I chose this mattress for sleeping this issue is just a minor inconvenience. I'm a mostly side sleeper enjoying pain free mornings thanks to this level sleep mattress.
I am so grateful for this wonderful product which provides pain relief for my autoimmune and osteoarthritis joint problems. I am now having a restful night's sleep and can more comfortably get out of bed in the morning. My quality of life has been greatly improved. Thank you to Zach for arranging to send it and the wonderful restore pillow to me in Melbourne Australia. My best wishes to all in the happiness team at Level Sleep. Christina Castles.
Great customer service. Delivery and packaging was easy. Mattress had no off gas smell at all. The cover is so high quality and breathable. Best nights sleep in over a year. Starting to see improvements in my neck and back pain after 10 days on it.
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!
This bed is phenomenal. A must for spine care experts and their patients.
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!
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.
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√¢‚Ç¨‚Ñ¢t think this was even possible.
I now have a total of three Tri Support Mattresses in my home and we love them! We were introduced to this product through a family member and at first we were skeptical and then when we received our first one...we were sold. We have had our mattresses for a few months now and there is no going back for us. Thank you Levelsleep!
We love the bed. My husband said this is the most comfortable bed he has ever slept on.
Both my wife and I were suffering from various pains upon waking every night. Since getting Level Sleep's premium mattress, we both have been waking up pain free. We love it! Thank you, Level Sleep!
I'm 92 and with the help of a 65 year old we had no trouble getting "THE BOX" up a couple stairs and on the bed. That was a couple months ago and so far we're very happy with the purchase.
And then my body adjusted to having lumbar support and my back thanks me every morning!
After the first night of sleep on my TirSupport mattress my back pain decrease by 80% when I got up the next morning. I am hoping that once my body adjusts to the mattress that my back pain will be eliminated.
I've been seeing my chiropractor for about a month with a back problem that was causing pain in my leg. After mentioning that I was having trouble sleeping because I couldn't find a comfortable position, he suggested looking at the Level Sleep mattress. After looking it over, I called with a few questions and ended up ordering a new TriSupport mattress. When it arrived, it was actually kind fun unpacking and setting it up. We've been sleeping on it for almost two weeks now and have definitely been sleeping better with less tossing and turning. My wife even said she thinks we're both snoring less now.
no back issues since Ive been sleeping on the bed- or shoulder issues.....used to have shoulder and neck stiffness in the morning and that is a non issue anymore. I think it would be best to have the special pillow also!
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.
I no longer feel painful back in the morning. Sleeping on my back seems to be much easier too. I really like it :-)
Very comfortable and good support but my arm always falls asleep if I sleep on my side. Is a less firm version available ?
I have slept better the past week than I have in the last year. The pillow is as much help as the mattress. I plan on getting the pillows for my children.
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!
I have questions and I want to speak with Zach. 213.595.5478.
So far so good I think it's a keeper
...a great night's sleep! This topper is amazing. From the very first night we slept on it, we were amazed how comfortable we were compared to previous nights. It arrived promptly and love that it was guaranteed to make us happy. It sure does. Highly recommend!
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.
Amazing mattress and Amazing company! I am a professional athlete who competes for TeamUSA and I can't believe the difference this mattress has made in my performance and recovery! If you are looking for a new mattress I highly recommend this one!View More Reviews
All I can say is: get it and try it. You will love it.
I got the mattress and immediately fell in love with how well it treats my back. I can sleep most of the night on my back, with little to no need to toss and turn. My sleep on this mattress definitely feels more restful, and I don't wake up with as many aches and pains. I had a concern with a seam on the mattress, and the customer service was superb. All my questions and concerns were treated patiently and professionally, and met with outstanding resolutions.
I would not hesitate to recommend this mattress to friends and family. I am happy that they offer such a great return policy, because even though I didn't end up needing to use it, it made getting the mattress feel like a safe decision.
I have had the OSO queen size mattress for about 3 months now, and I wanted to wait for a few months before rating it. My wife has had back issues for about 15 years and it seems like we have spent thousands of dollars trying to find the right mattress. We have tried every kind of spring mattress and even tried other memory foam mattresses. My wife has not been able to have a decent sleep in a long time often waking achy and tired. When we received the OSO mattress in a box, very neat by the way, I opened it up and let it puff up for a few hours before bedtime. We tried the firm end the first night and found it was a little too firm for my wife, so we rotated the mattress to the soft end. After three weeks of sleeping on the soft end my wife was still waking up with a sore back, which worried us. But, after the three weeks, she started sleeping longer than her usual 5 hours a night. It was gradual, but now she is up to a 8 or 9 hours of sleep a night and she is loving the mattress. I guess she needed to work out the kinks from the previous bad springy mattresses. Based on how my wife is feeling these days, I would highly recommend this mattress.
Thank you OSO for your amazing design!
I'll admit it, I was a bit worried about buying my mattress online. I mean, who wouldn't be?? That said, I could not be more pleased. I have had the best three nights of sleep I have had in years, and it's legitimately due to my new mattress. I love the plush/soft side, and my Boston Terrier loves the firm side!
Seriously - thank you for providing an affordable, well-built, non-toxic, comfortable bed.
I have had major numbing in both of my arms while I sleep since 11 years ago. I awaken numerous times a night and have to reposition my arms so they will wake up. My husband and I received our OSO mattress a few months ago. The first morning after sleeping on this mattress, I woke up and realized my arms were not numb. Every night since then has given me the same results. I am so happy to finally sleep and not have the numbing issues I was having. I just can’t believe how much of a difference a mattress would make. Thank you!!!
My husband and I have been sleeping on our new OSO for a couple months now. The setup was super simple. The mattress is supportive yet soft. Our favorite part is that we don't disturb the other person when moving/shifting! So glad we invested in quality sleep.
I really appreciate the option of using the soft or firm side of this mattress. I prefer the soft, and find it very comfortable to sleep on. My wife and I are able to move on our side of the bed without causing much noticeable disruption to each other. We are very impressed with our new OSO mattress, and are very glad we made the purchase..
We love our OSO Mattress. We bought it after reading a friends review and thought we would take a chance. We are so happy we purchased it. No other mattress has been this great, it offers support while still being soft and comfortable. Thanks OSO!
This is the first mattress that I've ordered that was delivered in a box and I'm never going back. It was quick, free shipping, and I was able to open it and lay it out easily. I love how soft it is and how well I sleep every night! I will never go to another mattress.
I'd forgotten the experience of a true, undisturbed 7-8 hours of sleep! But I have it most nights on our new OSO mattress. My shoulders sink right in given being a side sleeper and I'm totally acclimated to the soft side. Very happy with the experience!
We purchased this bed for our toddler daughter as her "big girl bed", and not going to lie, we are all a bit jealous of her at this point! It is so soft, but just firm enough for a toddler! It is actually also perfect for cosleeping, not to firm or too soft. We have another bed made by a similar company and this one wins by a mile. Recently my mom came over and layed in the bed saying her back hurt. After getting up she felt so much better she literally ordered the bed the next day! Big fans over here...clearly ;)
I've had probabaly 7 different mattresses in my life and this has been the greatest! I wake up feeling refreshed and not sore like I'm used to. It's quite an upgrade! Thanks Oso!
The OSO mattress is extremely comfortable - it is nice and soft yet still supportive. I like the removable/washable cover, which will make it much easier to clean when needed. I would highly recommend trying one and would not hesitate to buy another the next time I need to replace or upgrade a mattress!
This is a great mattress. This is my second foam concept mattress. I will never go back to the traditional box-spring style. It really provides support where it is needed most. I would highly recommend.
This bed is amazing. You will not find a more comfortable or versatile bed at this price!! 10/10 would recommend.
The mattress arrived ahead of schedule in a box that was smaller than I expected. The sales person I spoke to when buying the mattress told me that we should move the box into the room before opening it. We put the mattress in our frame on top of the box spring and as soon as we cut into the plastic the mattress started expanding. The vacuum seal is unreal on these things! Within two minutes we had a regular size mattress. This mattress is absolutely perfect for our guest room! When I called my mom to ask if she preferred a hard or soft mattress for her visit she was grateful to have a choice (she picked soft!). Thanks OSO!
My OSO mattress is seriously amazing! I love the option between firm and soft and honestly, they both feel great!
Whenever I have friends stay over, my favorite thing is that I can't feel them move at all! I would definitely recommend this mattress to everyone, especially to anyone sharing a bed!
Worth every penny!!
I had terrible back pain and then started taking tylenol before bed. That helped some, but I would still get up with back pain. We got this new mattress and I haven't had to take Tylenol for my back and I now wake up without pain and can finally enjoy my day!
I got my new OSO mattress two weeks ago, and have loved every night of sleeping on it. I've woken up without ANY back pain, unlike the tightness I had every morning on my old mattress.
I also love the versatility of being able to choose soft or firm! I had no idea what my preference was, and the OSO made it easy to take the leap because I wasn't forced to choose. (I've been sleeping on the soft side.) And with their return policy, I had even more peace of mind.
This bed is amazing!!! When it first arrived I unpacked it and laid down a few hours later (after passing out immediately on it) I moved it to my bedroom. I would and have highly recommend it to anyone!
My husband and I purchased our king sized OSO mattress about 2 months ago. We have been thrilled. The set up was simple and getting it into our condo (up stairs and around corners) was no big deal with the creative packaging concept. It also had no chemical odor when we unpackaged (which I was concerned/skeptical about).
We sleep on the firm side and both love it. It is as cool as it claims (no waking up with a sweaty neck and back). I also struggle with poor circulation and arthritis and used to wake up every night with limbs that had fallen asleep/very achy from the bends and pressure points of our traditional mattress.
I have had significantly less issues with the OS0 and feel comfortable highly recommending it for arthritis/back pain. When it's time to purchase again, we will stick with OSO and never go back to a traditional box spring.
We are happy to finally have a mattress that is quiet, and comfy to sleep on. For years our classic mattress would bounce and make noise with every turn.
The OSO is like lying on a soft raft, supporting the parts that need it most. We like the "firmer' end now but anticipate switching to the soft end as we want- I enjoy options.
If you buy an OSO, buy sheets with regular pockets (not deep) for a smoother, unwrinkled look.
Love the versatility of soft and firm. Moving it in was so great compared to moving out our old king (traditional mattress).
Overall we like the mattress a lot.
Ive had a Sleep Number for years me and my wife like it. But... even with 20 levels you still particular for no reason feel like you are sleeping on an air bed at your moms house lol. We got a California King OSO, to replace the Sleep Number California King. This was a great decision, my wife was so in love she sleep through her work alarms. Its a great bed, id recommend it to anyone.
I've had my OSO now for over 7 months and couldn't be happier!
At first I was a little nervous purchasing a bed online. However, the 101 Night Promise helped me make the plunge! I loved being able to try out the bed in my own home to make sure it was right for me. I currently use the soft side, but knowing I can change over to the firm side if my preference ever changes is very comforting.
In addition, as a (somewhat) recent college graduate who is prone to moving every few years, the flexibility of the foam mattress and portability (being able to fold it and transport in my compact car) is also a huge plus.
I usually wake up 1-2 times during the night. With this mattress, slept completely through the night. Materials look super high quality, love that I could fold it up to get it through doorways.
I love the Oso mattress. There are some nights when I need to lay on the soft side and other nights when I need more support. I don't have to worry about needing a new mattress for different needs. The Oso mattress has also been very kind to my back after major surgery. I love it!
I've had a king size mattress for a few weeks now and this thing is amazing. I have never owned a foam mattress before and this is a great introduction. I love that you can choose what side to sleep on depending on how your body is feeling that day. Top notch!
I’ve never really had a comfortable mattress before so this has been one of the best decisions we've ever made! I’ve struggled with back pain for a few years and my pain has significantly been improved and I feel a million and one times better during the day!
The first night we tried the mattress we slept on the firm end and had a great sleep. The next night we slept on the soft end. We slept ok but it just seemed too soft. Even sitting on the bed putting socks on, it was just too soft. We would love a mattress that was completely firm.
Very luxurious feeling mattress, yet with a sleek and modern design. I really liked the handles, made it easy to move into my apartment and it's lighter weight. I started with the firm side them switched to soft. Love my OSO mattress! Would highly recommend!
