It is essential for brands to have great ratings from sleepers. Mattress buyers give these mattresses better satisfaction scores than most other competitors, which should make you feel confident in doing more research into the product offering. Read the specifics below to learn if one will work for your body!
Being supportive is extremely important to how customers feel on their mattress and whether it provides health benefits to the spine. Overall, these mattresses do a fine job supporting the body for their firmness. So, you can rest easy that these mattresses will support your back while you sleep.
Most sleepers feel that the support towards the edge offers comfortable resistance. This means that you'll feel the same amount of support on the sides of the bed as the center and the mattress will prop most sleepers up rather than sinking.
Bowling Ball & Density Tests
Dropping a bowling ball on your mattress is a helpful way of testing support. These mattresses have good consistency in the feel of their surface layers, which is great for customers that are concerned about support.
One of the most important items for shoppers buying a new mattress is durability. Getting up to a decade of use out of a mattress is well rated in terms of longevity. However, some of the things that could affect durability are material quality and sleeper size. Customers give these mattresses good marks for durability against others. There may be a slight decrease in longevity for those that are larger.

My wife and I live this bed so much. When we don’t sleep at home we miss it. Very sound sleep every nightView More Reviews
Was pleasantly surprised with the support, comfort and overall better sleep provided by this mattress. I had a spring mattress for over 8 years and decided initially to go for a hybrid construction of spring and foam. This hybrid option eventually did not work out and I went with the all foam solution. All my initial worries were gone after that first night, the mattress does provide a good level of support and dissipates heat quite well. The only down side to this mattress was the smell it had for about a week after unpacking it, not a terrible thing to have to deal with for some days but not pleasant either. Regardless, I would highly recommend this mattress.
I bought the queen size mattress. It was delivered promptly and weighed 74 pounds. It wasn’t too hard to move around or dump out of the box (I have a low platform bed frame). Did a little adjusting of the cover or it would have opened lopsided. It is wonderful. It is supportive. There are no pressure points to cause pain anywhere on my body. I sleep with less tossing and turning so I’m more rested in the morning. I love my Leesa. Best $800 I have ever spent.
My Leesa is amazing. My back feels so good when I wake up in the morning (not always the case on other mattresses). I love memory foam but hate how hot it makes me feel and Leesa seems to have solved this problem. It reminds me of memory foam but I never overheat. And I don’t notice my wife getting out of bed in the morning. I paid a lot more for a Sleep Number and am replacing it with my Leesa!
Love this mattress! Firmness is perfect! I researched for a year and glad I chose the Leesa.
Going to bed has become one of my favorite times of day as a result of the Leesa mattress! Nicest bed I've had the pleasure of sleeping on!
I love the two Leesa Mattresses that I just bought. I now slumber in a deeper sleep. I don't wake up during the night tossing and turning, and look forward to going to bed! The pillows are fantastic. .
I love it. The best night sleep with out waking up stiff. It is very relaxing
We love our mattress! You sink in at all the right pressure points. We both especially like how our hips are sinking in just enough. It’s not slow to form like other memory foam beds, so when you roll over, your not leaving a hole and sitting on top. Our only complaint and the reason I didn’t give 5 stars, is the smell. During the first 2 weeks, it was pretty strong, it’s been about 2 months and it’s finally gone away for the most part. I’ll occasionally still smell it. I imagine all foam beds have this smell.
This is a very firm mattress. I wish there had been an option to choose a softer one. Also, deep-pocket sheets, which most new sheets are, do not fit well. They are much too big.
My whole experience with Leesa has been wonderful. I ordered the mattress and foundation and had the mattress two days later! The foundation takes a little longer but I had that within a week. There was very little off-gassing and I didn't find the smell offensive. I'm very sensitive to smells/fumes, I have asthma, but we were able to sleep on this bed the very first night. The mattress is THE most comfortable thing I have ever felt! It somehow manages to cradle you, like a big, soft marshmallow and provide the perfect amount of support. I suffer from multiple sclerosis and fibromyalgia and this bed has made such a huge difference in my life. I no longer wake up feeling like I've been beaten-up and while I rarely sleep through the night due to my illnesses, the rest and sleep I get on my Leesa has greatly improved my life. I've honestly never experienced this level of comfort! Thank you, Leesa!!!
totally awesome comfort after 6 weeks. Love it.
Best night sleep that I have had in a long time. The only downfall on this mattress is I never want to get out of bed!
I don't know why we waited so long
My wife and I LOVE our mattress. But that begs the question, how do you know you love it? First of all we aren't complaining about how we feel when we wake up anymore. We don't talk about buying a new mattress or even considering making a change. We fall asleep, and stay asleep (except when our 5 mo old wakes us). It's become a wonderful part of our evening, most nights I look forward to lying down! Great mattress for the price.
relieved that it's as good as the reviewers make it out to be and relieved that i turn much less than I did on a spring mattress. My wife's experience is the same. It's a deal.
We bought a king size Leesa for our master bedroom and loved it so much we bought a queen size for our guest bedroom. Our guests are going to love it!
I have to admit I was a bit skeptical that a mattress that is not super thick could be comfortable. My husband and I were both pleasantly surprised. The mattress has been wonderful. Not too soft, not too firm. It is well made with a beautiful cover. Love my new mattress
Best mattress yet
nice to finally get a good nights sleep.
Fell in love on the first night and have slept better since. It is the right amount of firm and soft and cannot tell when my husband moves next to me. I am a Leesa owner for life!
I am enjoying this mattress
I enjoy my mattress and will buy again in the future. Bed feels firm but contours to my back. It has lessened my lower back pain. Only gripe is that the mattress has a plastic smell upon opening that lingers. Had to leave windows open for a week to let it air out. Smell is still there but faint.
I love the matress and sleep great. It provides great support and breathes well. It still has a slight chemical smell from then it was made I guess but you get used to it.
Only reason I don’t give 5 stars is, LEESA tell us there may be some “off gassing” from the mattress for a few days. That means fumes emit from the mattress’s man-made material, a kind of settling process.
In the case of my mattress, it was like sleeping over an open can of paint for over a month. Then the “gassing” finally stopped.
I sleep really well on this mattress. Glad I bought it.
I'm a stomach sleeper and this mattress was too soft for me. I needed a mattress that was a bit more firm.
Our mattress has already developed troughs. It's still comfortable enough but there's no way it will last even 3-5 years, let alone the 10 a mattress at this price point should last.
We bought the leesa for our Special Needs son. He is 35 and has a hard time sleeping. He has loved it. Sleeps so much better and is in a lot less pain when he gets up. Thank you.
My husband just had back surgery and he has been loving the Leesa mattress. We both think it's wonderfully supportive and just the right amount of soft. We love it!!
Delivery and packaging was quick and easy. The light smell it had only lasted a day or two. As a heavier set guy, it felt amazing. It was super quiet, unlike a spring mattress. Very little disturbance with my wife. My wife on the other hand, hated the mattress. She's considered petite, and the more dense nature of foam mattresses meant she felt the Leesa to be a lot more firm than our last mattress. Sadly, I ended up returning it for her. It's a great option for medium to large folks. By the way, the return process was a breeze and refund processed about 5 days after the pickup. Amazing service.
My fiance and I are about a year into our Leesa experience and for both of us, it's been the greatest investment. She and I both travel extensively and we sleep in a lot of hotels but no matter how much we enjoy the mattress, we always look forward to coming home to the Leesa.
Super soft and well made mattress! We have been impressed with the quality and how it’s almost impossible to have a bad night’s sleep on it. It does run a little hot but I’d imagine not as hot as other memory foam mattresses due to the Leesa’s thoughtful construction.
I have gotten the best sleep ever! I’m a back and side sleeper and it’s been amazing for me! Definitely worth the investment! If you’re going to buy a mattress that will last and will allow you a great sleep, go with LEESA!!!
comfortable and supports my back well while being comfortable
Bought this mattress for our son, he is a very big boy, hoping the mattress won't start sagging in hot e middle as every other mattress we have bought for him! We will see!
I've been having difficulty sleeping due to a injury. I purchased the Leesa mattress and was finally able to get a decent night sleep.
After sleeping on this mattress for over a month, I’m ready to review it. This is by far the most comfortable mattress I’ve slept on. I also upgraded from my queen mattress to a king, which has been excellent. Along with the great sleep I’m having throughout the night, I’ve noticed I no longer wake up when my husband adjusts or gets in and out of bed. Experience with this mattress has been great!
For me, the Leesa Mattress has proven to be a wonderful mattress. I have bursitis in both hips; I have had zero hip pain with this mattress. I sleep soundly, comfortably. If my kids hop into bed with me, they can move without disturbing me, and vice versa.
I highly recommend trying this mattress. What price would you put on a peaceful night's sleep?
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!
