Some sleepers are cozy with these mattresses., but others have had complaints with the mattresses. Sleepers were mostly positive, but there were some negatives that they described. Research more below for information on the specifics.
These mattresses are better than average when it comes to support, which is refreshing for those struggling with the aches and pains of a sagging bed. However, some have had issues with support long term, so mull over the reviews to make sure that your choice is going to work for you.
Edge support is a mesaure of the supportiveness along the sides of the mattress. These mattresses have good resistance, but some may exerience some dipping along the sides.
Mattresses don't seem to be as long-living as they once were. A mattress that lasts 15 years is a hard thing for find. Yet, finding a mattress that really remains comfortable that long can save you lots of money. Sadly, sleepers have mixed feelings about these mattresses. Many folks feel comfortable with their mattress and are happy, but others have issues with comfort on a quicker time frame than average.
Most customers reviewed these mattresses highly and felt comfortable in their beds. Some, however, didn't feel share the same delight. If you are considering buying one of these mattresses, make sure to read our analysis below.
Folks usually think that mattresses that are good at support are always firm, but when we write about support, we are talking about material that aligns the spine. These mattresses are well rated at giving support to the average sleeper, but some have limited complaints about feel.
Most experience these mattresses as having desirable edge support, which is great for those that like to sit on the side of the mattress or roll over towards the edge at night.
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 are supportive to most sleepers overall, but there are a rare few who report feeling some discomfort.
All of us want a highly durable mattress that lasts forever, but that is sometimes easier said than done. That said, data on materials, customer reviews, and tests make things a bit easier. These mattreses have good durability and should last longer than average, but some heavier folks may experience them to be slightly less durable.
First off, let me say the mattress is extremely comfortable. I really like it. It's soft, it stays cool, and conforms well. I'm a big guy 6'2'' 275lbs and I feel great in a queen. The real pleasure of buying this mattress though was the purchasing process. It's extremely easy. This was my first mattress purchase online and I don't think I'll ever buy a mattress in a brick and mortar store again. You don't have to deal with annoying salesman, it's cheaper, and it's way easier to get it to wherever you're putting it. Don't be intimidated if you've never ordered one online before - it's so much easier. I couldn't be happier with my purchase so far.View More Reviews
While the selection and ordering process or smooth and the folks at Kiss were great to work with, it's a little too soon to tell how happy we will be with the mattress. We ordered a plush and it is quite firm. I had hoped to be used to it by now but still think it may be too firm. While I am not looking for squishy, just a little more plushness would be super.
The service from KissMattress is amazing. So far they have done what they said they would do for me and more. I found the mattress to be a little bit firm, but I do like it, so as promised they sent me a topper for it when I asked (no additional charge). The topper was nicer than I expected and helps me fall asleep at night. I really like their business model of being straight forward and telling us what we are getting from them. I look forward to seeing how the bed wears into the warranty period, but if they stick to their word in the quality of the product as they have in getting it to me and making sure I'm happy with it, then I'm sure it'll go splendidly.
I purchased a plush queen size Kiss mattress about a month ago. It's the third mattress I've tried in as many months and it's the one I'll keep. My experience is that the Kiss conforms nicely but does not envelope me. I don't have pressure points on my back or side, but I still feel well supported. It has the kind of softness that allows it to 'give' under curves, but it doesn't feel pillowy. Best of all, the mattress helps me maintain a neutral sleeping temperature. It's very breathable and that's a hugely important to me because I sleep hot. This is a very comfy mattress, middle of the road softness, great for combo sleepers, and great for sleepers who get hot at night. I am extremely pleased with the purchase and cannot wait to get in bed.
This mattress is great! I sleep through the night, no back pain or stiffness when I wake up.
Even though it is still a little bit soft for my taste, it is a great mattress, great body support, no back pain anymore, not hot at all, and I live on Florida.
slept on it 4 times now like it so far
The mattress is very comfortable, though more firm than I expected. Overall, I'm very happy with it.
Customer service helped me choose a firm mattress. I am happy that I went with Kiss. I really have been having the best sleep when I'm on my the new mattress.
Your customer service was phenomenal! It's great to have a mattress delivered right to your front door.
Definitely worth the money! Hands down most supportive, comfortable mattress I've ever had.
Perfect mattress; very plush and cool to sleep on (the real reason I was in search of another mattress).
First off, let me say the mattress is extremely comfortable. I really like it. It's soft, it stays cool, and conforms well.
Great experience from start to finish. Bought kiss mattress and foundation. Customer service was quick to answer any questions.
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!
