With brands doing lots of work on their online reputation, it's pretty hard for an average shopper to get to the bottom of customer satisfaction. That said, these mattresses are reviewed well by customers overall. However, there were some sleepers that didn't like the feel. so keep reading below to check your body type with the specifications of this mattress!
Folks describe these mattresses as good at support. Though there are a few folks that don't like the firmness of these mattresses, most would describe these mattresses as having the right amount of support for them.
Edge support is really important for those that struggle with mobility or roll towards the edge of the mattress at night. Customers report that these mattresses have decent edge support overall and they should support most customers comfortably.
Bowling Ball & Density Tests
Bowling balls are a good way at measuring mattress support and firmness These mattresses provide above average evenness in support across the surface, which means they should do well elevating your body comfortably.
Every mattress buyer is looking for a mattress that will continue to sleep comfortably after a decade. Though there might be some factors, like our bodies, that would mean that we would still want to a new mattress after 15 years, we would all be happier knowing our mattress could last that long. These mattresses are good overall when it comes to longevity. Most sleepers will be comfortable with these mattresses over 7 years, but some had issues with the feel. If you are a heavier person than average and worried about durability, do some additional research to make sure your selection works with your body.
If you are considering this brand, take a look below for more from customers Sadly, they don't get the best reception from all customers. Some customers had positive things to say about their new mattress, but others didn't feel good about the comfort.
Support is a bit different than firmness. Deep support means the mattress aligns the back and spine. Sadly, these mattresses have some mixed reviews when it comes to support. Most are satisfied with the supportiveness of the mattress right after purchase, but some have reported support issues as time as gone on.
For those that like to sit on the side of their bed, even edge support is essential. At first, these mattresses do a good job with edge support, but some found it didn't last as well as they would have hoped.
In addition to having good support, having a mattress that really lasts is key for shoppers. We all wish that our mattress would be just as comfortable a decade later as it was the first day. However, these mattresses are not rated well by some reviewers on durability and some have experienced breakdown after only a short time. If you are considering purchasing as your full time mattress, read the reviews to make sure that it will match your body type before buying.
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!
We had a very firm serta icomfort that hurt my hips. I'm a side sleeper. Last year we added one of the latex toppers. That helped, but not enough. We recently got a medium mattress and are using it with the topper. It has been great!View More Reviews
The firm is fit for us. I am pregnant, this one helps a lot
It’s a great mattress though mine only is about 8” since the wool and cotton has not yet full expanded. I have great sleep at night, no aches or pains.
We have ordered 3 queen size beds for our new home. Not only do we love the mattresses or guests do too! We also ordered 4 deluxe pillows, which we are not as happy with. They are too thick which make them uncomfortable.
We purchased the firm latex mattress. It is very firm, but we are comfortable on it. As has been mentioned in other reviews, there is a smell to the mattress. It is going away over time, but some people might find it objectionable. It is also a heavy mattress. We purchased it for our boat and there are storage lockers in the platform on which the ...Read Moremattress lays.

Stands up to all the claims made by it's inventor ! Better more relaxing sleep than on any other mattress, hands down. Also, the price is reasonable and the Customer Service is fantastic. !!
In an attempt to remedy chronic back discomfort & having more preference towards firmer sleeping surfaces... I initially purchased a medium 3" topper to firm up a pillow top mattress. When I received it, found that I would've preferred the firm topper as the medium didnt do much. With plans of returning the topper, I decided to go ahead and pu...Read Morerchase a latex mattress, choosing the 7" firm. Interium I slept on the topper placed on a carpeted floor. Those few nights were THE BEST sleeps I had in a long while. Firm enough for me to feel the support of the floor, yet cradled enough by the topper that it wasnt too hard. Also noticed that I didnt wake up with my normal morning stiffness from the pillow top mattress. Shipping for mattress was just as quick as the topper. Upon opening there was a farm animal smell mixed with latex, which was strong enough to be off putting to me. I also noticed sagging in the middle of the mattress once it was laid onto my platform bed. I phoned the company & the customer rep assured me that it would take a few days to a week for the mattress to full expand to its capacity; and if it didn't, they would ship a new mattress. I found the firm to be TOO firm(I'm a side sleeper) & bouncy, so I put medium topper over it. I felt like Goldilocks, it was just right!! Even masking the zoo smell from the mattress. Now having slept on the mattress & topper for nearly 2 weeks, I have to say that I am getting some of the best nights sleeps ever!! Even my housemate commented how comfortable it is to lay on. So I wont be returning the topper, happy to know that if I go thru a phase of needing more firmness, I can always remove it. Oh, I also noticed that the animal smell as calmed down a lot, needing to place my nose close to mattress to detect. I do wish the mattress had handles. I am very happy with my investment, 3 stars for now, will return after 6 months with an update; as only time will tell how well they both hold up from use. Read Less
Solid, way to firm. Will probably return.
Best mattress my wife and I slept on in years. Everyone needs one!
I recently bought a 9 inch Pure Green Natural Latex Mattress and am very happy with it. I wanted to avoid the off-gassing of memory foam so I was specifically looking for a latex mattress.

This is the best mattress i have ever owned. Its supports my body well and is comfortable too! It is very heavy to move tho.
I got the firm version of this mattress, and it’s great for back sleepers (maybe a little too firm for side sleepers). I’m not giving it five stars because I don’t recall being warned anywhere that the queen size mattress weighs 150 lbs. I’ve since learned that latex is heavy, and I think it’s great for some people.

I decided to return it, and I’d get the regular instead of the firm if I did it again. I’m opting for a lighter mattress. They offered to let me donate it, but since it’s so heavy I asked that they pick it up. They’re sending people who will carry it back downstairs for me, and they were extremely pleasant and understanding about the return. They’re definitely a quality operation, and I’m sorry it didn’t work out for me. Read Less
The Pure Green is really well constructed from materials that feel durable, especially the primary material, which is a huge slab of latex. I much prefer the feeling of the latex mattress to memory foam, and I like that it's cooler than foam mattresses. Highly recommended.

I really, really loved this mattress for the first few weeks...it felt amazing compared to my old bed. Now that I've had it for about 8 months, I'm less sure. I bought the medium firm mattress, 9 inches thick. I waffled between firm and medium, and ultimately chose medium after talking to an employee, because I often sleep on my side and some...Read Moretimes sleep on my back and that was the recommendation. It seems like it has already lost a little bit of it's firmness, which I thought was not supposed to happen. After about 3-4 months I started really wishing I had chosen firm. Hopefully it doesn't soften further. Some Pros: The price! I could not have afforded most of the other brands of natural latex mattresses out there. Also, more comfortable than many other conventional matresses. Another issue is the mattress itself is a little (1-4 inches) narrower and shorter than advertised, than a typical full size bed. Maybe factor the thick wool cover into the advertised mattress dimensions, which seems misleading. I know it's just a few inches but it felt noticably narrower to me than my conventional full mattress. Overall, I'm still undecided. I'm happy to have been able to afford a more eco-friendly and healthy mattress. I wonder if I expected too much, comfort-wise. Since I did love it at first, I would kind of like to try the firmer mattress instead...but am worried I'll just be disappointed again. Read Less

This mattress is great, we got a medium firmness because so many people said the medium was really firm. I disagree, I think the medium is appropriately categorized and thus we are returning for a firm. It’s super comfy but we have an infant and need a firmer sleep surface.

Fantastic mattress! I was very apprehensive about purchasing a mattress online but so happy now that I went with SleepOnLatex.

I am enjoying the new 9” king soft-firmness mattress. However, if you enjoy memory foam, this may not be for you.
