Most customers feel quite comfy with these mattresses and they gave them high marks overall. There were, however, a few that didn't have as great feedback. If one of these is one your list, make sure to read on to make sure it will work for your body.
Mattress support is important for keeping your spine well aligned and sleeping well. These mattresses are above average in supportiveness across all sleepers. This is important if you don't have a supportive sleeping surface right now. Most customers report that these mattresses do a decent job providing support.
Edge support is how much resistance there is along the sides of the mattress. These mattresses offer good edge support overall, but some customers may experience more contouring along the edges.
Bowling Ball & Density Tests
The bowling ball and density tests are good measures of mattress firmness. It is also great for those that want to understand if a mattress provides even support. Overall, these mattresses will offer an evenness across the sleeping surface.
All mattress buyers want to find a mattress that will sleep comfortably after a decade or more. Though some factors, like dust mites, are reasons why keeping a mattress for longer than 15 years might not be the best idea, we would all be happier if we knew our mattress would really last. Customers are pretty content with these mattresses when it comes to their durability. Most sleepers should feel confident that their mattresses should last over 7 years -- with only a few folks complaining about feel. If you are a larger person, make sure to do some extra research to make sure that these mattresses will work for your body.
If you are thinking about this one, do more research below to learn if this mattress will work for you. Unfortunately, they get poor ratings from some customers. Some customers were elated by their selection, but others felt let-down overall.
Most customers describe these mattresses as having above average supportiveness, which is hopeful for those that are looking for something to align their spine at night. However, some have had issues with support long term, so make sure to do some extra research on the firmness and whether it will work on your body.
Edge support is how much resistance there is along the sides of the mattress. These mattresses offer good supportiveness for most, but some folks may experience some contouring along the sides.
We all want a mattress that is going to last over a decade, and when our mattress is something that instead gives us pain over a short term, this is terrible. That said, finding a durable mattress nowadays is really hard. With more products available than ever, some brands are sacrificing quality. With these mattresses specifically, some sleepers report problems with lasting comfort. Not every customer experiences durability problems, but do some extra reading to make sure that your choice works for your body.
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!
Unfortunately we have returned it due to both sides sinking Leaving a huge hump in the middleView More Reviews
This bed was delivered by two men from 'manna delivery' services, they did a good job and took away all of the boxing and giant bags. It is a little taller than i thought but its not too tall for my sheets which is good. It feels a lot different than my old memory foam bed and when I called they explained what latex foam was and really opened my eyes. My back pain has gone away and also i sleep better throughout the night. i would buy this bed again
Tried to like this matress but it's just a poor product. Weak sides making you feel like you're sliding off edge. Hump formed in middle after a few weeks. Valleys on the sides. Almost impossible to rotate due to lack of handles / straps to hold on to. Even tried to flip it over and all the problems come back on both sides.
We like a firm mattress but this is hard and uncomfortable. Harder than the sliding diagram indicates. My husband and I had back, hip and shoulder pain after the first night. Returning it asap.
After seeing the bed in Costco and feeling how cool the foam was, i was convinced it was a good buy .....but....when foam is covered with fabric, then a protective pad then a sheet the bed was just as hot as my last memory foam bed and after 3 months, it is starting to get indentations in it even though we rotated it several times. I will return it to Costco.
Believe the reviews this mattress is firm! We've had it for about 9 months and still can't get comfortable. The sides have depressions while the middle has a hump. We have rotated the bed as instructed but still does not help. My wife and I aren't big people, and we both have back aches from this mattress. We gave it a try, but unfortunately have not had a good nights sleep. We are going to return it and get something softer.
I have purchased 3 spring Air beds in the past, so did not hesitate to order online. Delivery was very efficient and on time even though I live 175 miles from the nearest Costco. This mattress is very comfortable from day one.
The Latex is great for hot sleepers! This bed does not make me sweat like memory foam or any of pillow tops. I never ever feel hot. It is a firmer plush if that makes sense. It will soften up after about 3-4 weeks. I originally bought the Ultra Firm model but I could not take that slab of concrete and had to return it for this one. It is definitely soft on the sides and firm in the middle. If I were single I'd sleep in the middle to make the bed even. With the firmer middle it is harder to roll over and my wife doesn't try to sneak over to cuddle and steal my heat. I tried 7 other mattress's foam/spring/spring infused latex with foam tops I thought I was going to go crazy, until I found this model. I was desperate for a King size, medium firm, cool bed for $1500ish.
great mattress. firm and had good nights sleep from day one. the delivery service was efficient and courteous. they arrived in the time frame that was give and took away all cartons and papers. would recommend this product .
The consistency of the foam is uneven, hard in middle too soft on sides. Makes you feel like your tilting towards outer edge when laying on back. Seems also to have broke down to a lumpy feel after six months use. Very difficult to change positions as it leaves you feeling like your trying to roll out of a hole. Made my good back hurt. Can't sleep on this mattress any longer, returning.
There was an error in shipping by delivering the wrong foundation, so we had to use our old one, which made the mattress seem soft,but still very comfortable. After using the correct foundation there was a distinct improvement in the firmness,this is the best i have slept in along time especially having physical issues.I recommend you use the right foundation. We are very happy with this, also read the rotating instructions.
Way too soft! You sink right in and it's comfortable at first. But when I wake in the morning I have a terrible lower back ache due to lack of support. I'm a side sleeper and this mattress does not have proper support to keep my spine aligned. This is suppose to be a Latex bed, so I don't know why they add junkie memory foam to the top layer which only makes it hotter and does not breath, completely defeating the advantages of Latex breath-ability and cool sleeping surface.
When I saw this mattress advertised as plush I figured it would be very soft. That is not the case. This mattress is quite firm. It is probably fine for a back sleeper, but I sleep on my side and it's terrible. After the 3rd night I couldn't take any more and put an old memory foam topper on it. As soon as the replacement mattress arrives this one will be heading back to the warehouse.
I was especially interested in getting away from springs and trying the Latex. Unfortuneately, it was a big dissapointment. It seened lifeless, like sleeping on a bag of soft beans. It definitely was not like a cloud. The positive reviews on a similar Spring Aire latex matress are astonishing to me
I have to say, I was a little hesitant on purchasing this after reading the last review but I must say this was one of the best desicions I have made in a long time. This mattress is sooo cushiony and comfortable. For the first time in a long time, my husband and I have actually been sleeping through the night!
We have had this bed for about a month. From the first night, neither my husband or I wake up with sore/stiff backs. We bought our previous bed from Costco and were hesitant thinking we should go to a mattress store. We are so glad we went with this bed. I prefer a softer bed and my husband prefers a firmer bed. While this bed is firmer than I expected, it doesn't effect the sleep we are getting. We also didn't notice a smell. The manufacturer said to let the bed air out but we didn't need to. Hopefully this will continue to be a great bed! We have struggled over the years, trying less expensive options. This is worth every penny.
We were on the hunt for a good mattress, but did not want memory foam. The options are limited. After doing some research we ordered the Spring Air Firm mattress. It was too hard. I contacted Costco.com they arranged for pickup (free) of the other mattress and provided a refund. We then chose this mattress. It is still firm, but not hard. Its supportive and comfortable. Shipping was included in the price from Costco.com, and we had no issues with setting it up. My husband is also very pleased with it.
One word: stone. This bed is soooooo hard and not plush at all. I'm a loyal Costco shopper, but this product is a total fail. It will be going back for sure.
