Customers have mixed feelings about these mattresses when it comes to lasting comfort. We're all after mattresses that feel just as great now as they did 10+ years ago, but unfortunately not all mattresses last for the long term.

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!
This bed was perfect and everything I'd hoped it would be... at first. After having if for a few months it seems like it's wore down in the middle of the bed where I tend to lay more often. If I try to lay on the edges I just roll to the center. It seemed to good to be true at first, but I don't think they're built to last.View More Reviews
I feel like it already may be sagging in the middle since that is where I sleep the most, but is very soft and comfortable
I waited a long time to write this review because most beds are great when you first get them. But there are huge sleep indents where my wife and I sleep, and one big raised lump in the middle of us. I'm a big guy over 250 pounds, but my wife is barely over 100 pounds. I understand how my side has been messed up, but not hers! Now after 18 months of sleeping on the mattress it is way too soft and way too lumpy and we are searching for a better brand.
I wanted a memory foam mattress for years after sleeping on one on a hotel. I refuse to pay $3000 for a mattress. I bought this after reading the reviews. I have had the best several months sleep ever. I don't wake up sore anymore. We did not experience any of the smell reported in other reviews. You absolutely cannot beat the price!
The mattress arrived timely. We let it rest a couple of days before using it on the bed. There was little to no off-gassing smell and my niece says it sleeps very comfortably. Very good purchase! Thank you.
When I see this in the Amazon Primeday, I said to my self 'I Want One Of Those'. I have full size bed frame that needs a bed mattress. As advertised, a full size is measured 75 x 54 x 10. I like as it is 10 inch thick. Ordered a full size, got it. packaged like a vacuum seal, it is heavy . Opened and placed it on my bed frame. And now I said to my self, Oh! NO!! S....!!!. It is wider than it is advertised. It is 56 inch wide, and it won't fit my bed frame. Mattress is firm and has a nice cover. I will return it and now my problem is re-packing it back to its box. Maybe return it in several pieces. Very dissappointed
This mattress was a steal!! I was so skeptical due to the low price but I am SO happy I ordered it anyway! It's firm, yet soft. Excellent quality. I've never slept so well. The only downside is being so comfortable that it's difficult getting out of bed in the morning!
so easy to set up. SUPER comfortable. My husband who is in chronic pain from just being a dum-dum when he was young sleeps better on this than any bed we have ever slept on.
Wow, I love this mattress. Just a fair warning, I never owned a memory foam mattress before this 1 so maybe I'm just too biased towards it. It's firm enough to support me sleeping on my back and soft enough for me to sleep on my side with no issues. It supports edge sleeping very well not that I like to sleep on the edge since I tend to fall off my bed when I do lol. The only thing I really really really disliked was the VERY strong smell coming from the mattress when you first unwrap it. Highly recommended you let the mattress air out for about 2 days. After I've done that I haven't smelled anything coming from the mattress.
I used to have insomnia. USED to.
The mattress is great I would say up their with the serta i comfort line and without the high price.
The mattress has great support for the body and even has edge support and does not heat up like other memory foam mattress.
I am not really a one position sleeper and have no complainants unless you want a extra firm or a ultra plush mattress as I would rate it the sweet spot.
I love this bed. I was a bit skeptical initially as I have never purchased a bed without actually going to the store, however I did a little research on the company and made the purchase. I am very happy with it. I look forward to purchasing another one when I have a place to put it.
It was hilarious seeing a queen size mattress come out of that (relatively) tiny box. It had hardly any 'memory foam' smell out of the bag, even less after letting it sit for 24 hours. Very comfortable, but one of the firmest mattresses I've ever slept on. If you don't like a very firm mattress this might not be the mattress for you.
Good mattress for the price. Hard to tell if it will hold up over time. Edges a bit soft.
I received what appeared to be used mattress with oil on one side and tears on the other.
We have had the mattress about 3 weeks and it has exceeded my expectations. My old mattress was very expensive and it was never this comfy. I always woke up extremely hot and sweaty,so you know my concerns about switching to memory foam. I'm soooo pleased ,cool and rested. LOVE IT!
This bed is firm. If you like a firm mattress, you'll probably love this one. Personally, I expected more shape contouring from a bed this expensive. To find out why it's not great I unzipped the top cover to discover it is simply an 8-inch piece of upholstery foam with a 2-inch piece of memory foam glued on top. That's it.
On the plus side, the cover is stretchy and seems like relatively good quality except for the fact that it has a part where it wasn't sewn correctly and is falling apart along 2 inches or so of the seam. My wife likes (but doesn't love the bed). I am sleeping OK, but find it uncomfortably firm. I've gone ahead and put another 2 inches of memory foam on top of the bed and I'm hoping it will soften things up to my satisfaction.
Another positive feature is that there was very little odor when we opened the package and it dissapated quickly.
