These mattresses are highly rated by customers overall and most feel very comfortable. However, some sleepers didn't sleep as well. If you are thinking about buying one of these mattresses, make sure to read more about these mattresses below to make sure it will work for you.
A mattress that supports your body is what matters to a healthy spine. If your mattress doesn't support you well, a mattress that properly supports you could mean deepers sleep and a happier you. These mattresses have been rated above average in support, but some had issues with how they felt for them.
Most find the edge support that these mattresses provide to be good, which is good for those that enjoy sitting on the side of the mattress. Those that have heavier frames may still find some discomfort while laying close to the side.
Reviewers provide mixed ratings about the durability of these mattresses. Everyone wants to find the comfy mattress that stays that way for 10 years or more, but unfortunately not all mattresses last for the long term. If you are considering buying a mattress with mixed reviews on durability, double-check the trial and warranty policies to make sure you are comfortable.
With reputation management, finding out customer satisfaction isn't terribly easy for the average shopper. That said, customers report feeling comfortable with these mattresses overall. However, there were some complaints from sleepers that didn't feel as comfortable. so take a look at the research below to make sure one of these mattresses will work for you!
Mattresses that give good support are oftentimes thought of as firm, but when we mention support, we mean support that cradles your spine, hips, and shoulders. These mattresses do a good job providing support for the average sleeper, but rarely, some customers are not so sure.
Most experience these mattresses as having desirable edge support, which preferred for those that like to sit on the edge of the bed or sleep close to the sides of the mattress.
Bowling Ball & Density Tests
The bowling ball test of even support is important to figure out if the mattress will provide a good surface to support the spine. These mattresses do a good job at supporting the spine overall, but you should do additional research if you have a larger or smaller than average body type.
Longevity of comfort is one of the most important factors in selecting a new mattress. Though some factors, like dust mites, are reasons why keeping a mattress for longer than 15 years might not be the best idea, we all would rest easier knowing that our mattress would last that long anyway. Customers are pretty content with these mattresses when it comes to their durability. Most folks will find they last over 7 years, but there have been rare complaints about feel. If you are a larger person, you may want to do a price analysis to make sure these mattresses are for you.
Don't get me wrong, it is an okay mattress, but not the kind of mattress that I was really after. I got sold on their Octaspring tech, but in all it just makes weird bumbs in the mattress. I didn't feel as supported as I was before.View More Reviews
The Dormeo bed has a bounce to it that other beds don't. It's good for snuggling up with your SO if you know what I mean. :) Highly recommended.
I've had my new bed for a couple months and it already has some weird dips in it that weren't there at the beginning. I don't feel anything differently yet, but I expect that it may sag soon.
I just love this bed. It is really comfortable and curves to my body when I sleep, which is exactly what I was looking for! I might even buy one for my kids because I love it so much!
I knew I was taking a risk when I selected this mattress because it is new technology, but overall I really like the feel. It's unlike other beds that I've had.
Truly Great Mattress, so comfortable and supportive
I am very pleased with this mattress. It took some getting used to. Having slept on it for 3 months now, I can feel a difference in my back. The support it provides is excellent. It is unfortunate that I couldn't try the mattress before buying, but based on the description from Dormeo, I went for it. This mattress feels as good as other well known and more expensive memory foam mattresses. One negative is that there are no handles on the sides of the mattress to enable rotating it. So it is difficult to hold it to rotate. It comes rolled up, and then you open it and roll it out. But if I had any reason to return it, i don't believe i would ever be able to fit it down the stairs again. Fortunately that is not necessary for me, but worth considering before buying.
We brought this mattress after suffering problems with back pain with our previous mattress, this is a well built and quality matress and the Octaspring technology seems to work well. Only snag I have is that its starting to become soft in some areas after one week of use hence why I’ve given it 4 stars so far. I will review this again after 1 month.
Wonderful, firmness perfect, can lie on it all day, like I sometimes need to do without the usual backache from my old mattress. It is worth the money, and I look forward to going to bed every night now.
It's medium/firm so excellent for lying on back and good for side sleeping as well, I just prefer the Mistral as it's softer at the shoulder end due to the different zones
Very comfortable except at the edges. Bought it for my back problems. Getting a comfortable nights sleep but find that when sleeping over 8 hours, back hurts a little.
A very comfortable mattress, you'll sleep wonderfully on it. It can't get 5 stars though, mainly for one of the reasons you'll see on the reviews that told you how good the mattress is. It's very thin, which you don't notice when sleeping on it due to the foam they've used. The problem comes with bedding, mattress protectors and fitted sheets, even Dormeo's own are for thicker mattresses. You'll constantly find yourself rolling over on big clumps of excess sheet, your protector will move around a lot. It's a shame because the mattress is great, if only Dormeo would make a protector and sheet for this mattress specifically...as this is the only decent mattress on the market that is this thin.
If I am honest, the mattress is not a comfortable as I imagined it would be. Although, for the price I am not complaining as it is still a good mattress. I think it may just be a bit harder that I thought it was going to be. I still seem to end up in the middle of the bed for some reason?
This mattress is the best. It comes vacuum packed and needs to be unrolled and left for several hours so that it reaches its maximum capacity. Bought for rugby player who finds that it is the best mattress he has had. His body is perfectly supported from top to toe and he has a very relaxed deep sleep. Would recommend this mattress to anyone who suffers from aches and pains.
I am delighted with the mattress it is comfortable and seems to be helping to alleviate some of the pain I experience due to a long-term condition. Still getting used to the pillow but it was free so I am not complaining - its firmer than my previous pillows so I am adjusting to it over time. I would certainly recommend the mattress, I am delighted with it.
It's really comfy and I'm very happy with it. It's not too hot, as with some thicker memory foam mattresses. It took about 8 weeks for the new chemical smell to disperse though. Given the chance it would be better to air it for as long as possible before using. I gave it two weeks, but longer would have been better.
This was O.K. However my Dunlop was just the same, so no better or worse. The pillow was dredful. Hard, couldn't get it to shape my neck or head. I think these are pilowas they can not sell.
High quality, very comfy mattress - pleased with purchase. A bit thinner than I imagined it would be, but it is the size stated, so it was me imagining it to be higher that was the problem.
We thought we would sleep a lot better than we use to. Perhaps we expected too much.
Very comfortable, no sign of the back problems which plagued me for years
Although this mattress is a lot 'thinner' than others I have had - so my wooden frame is almost as high as the mattress, it is excellent - exactly as it says. And whilst I still don't sleep as much as I should do, it has certainly made a difference. Definitely recommend !
I bought this mattress for my Son, he has joint problems and is a big lad about 15 stone, he loves the mattress,He was skeptical to start with as he helped pay for it. he says he has never slept so well
Absolutely love it ,had a memory foam mattress before this one which was excellent ,so after lots of research decided upon this after reading many positive reviews .Highly recommended .
The mattress is very comfortable, good depth and feels great. As I already had a memory foam mattress that I purchased many years ago at a much greater price i
Thought my old mattress & topper could not be beaten but it has. So comfortable, sleep came easy & following day just feel rested & ready for the day ahead.
It does the job. I grew up in foam mattresses and at a fraction of the price of others it's a good deal. The smell took a long time to fade though
Delighted with my new mattress. I never realised what a good night's sleep was until I bought this mattress. So comfortable
So much cheaper than alternatives of same quality. Love the cooling layer which offers a little give to the firm memory foam
Very comfortable - best I've had! A bit too warm in hot weather, but the comfort makes up for that.
I was very happy with the size fit on to my bed frame very well. I would recommend this to others.
Great product, easy transaction and super quick delivery. I'd certainly order in line again.
Superb value for the money! Really happy with this Memory Plus mattress. Nice and comfy!
Fantastic best sleep as I'm disabled I've never slept so good now sleep night through
comfortable supportive mattress - good for relieving aches and pains after a long day
I find I am sleeping a lot better without a bad neck and back in morning
Very comfy mattress, great nights sleep.best thing I have ever brought.
Excellent product, excellent quality very comfortable nights sleep.
Awful products and terrible customer service
i got the classic not as good as they claim thinner than i thought fitting a double sheet on it its very loose so not got much to cover so rucks up when you sleep on it so you sweat anyway very overated to the adverts they put on tv
WARNING TO ALL FUTURE POTENTIAL CUSTOMERS... I bought a mattress from this company, it arrived and was not fit for purpose -low quality, not as advertised. Upon returning the mattress a charge was deducted from the refunded amount. It was previously agreed over the phone to resolve this issue that it would be collected indicating I would be refunded in full. After challenging them about why they don't want to abide by consumer law they say it's in their fine print... So my advice after appalling customer service call is on their FAQ page it states "if you are not completely satisfied it can be returned for a full refund" - this is not true!
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!
