Customer reviews are a powerful resource for finding out if a product will match your needs. These mattresses are rated very well by customers overall, but there are some that didn't feel as comfortable. Look at the details below to see if one of these will work for you.
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 are suffering from lack of support currently. Most customers report that these mattresses do a decent job providing support.
Edge support is how much supportiveness there is along the edges of the mattress versus the middle section. These mattresses are well rated on their edge support, but some customers may notice more contouring along the sides of the mattress.
Bowling Ball & Density Tests
By placing a bowling ball on the mattress, one can figure out mattress firmness. It is also great for those that want to understand if a mattress provides even support. Overall, these mattresses will give a good amount of evenness of support.
Finding a mattress that is long-living is key to shoppers. But, with mattress makers competing strongly for profits, it isn't always simple to discover. That said, based on data from customers and materials used, these mattresses should be good for durability and provide over 5 years of comfort for most. But, some folks who are heavier may find their mattress loses some durability.
There have been diverse feedback from sleepers about these mattresses -- both good and bad. There are reports from many folks of good initial comfort and happiness with their purchase, but there were others who were not as comfortable. Make sure to read more below to make sure one of these mattresses will work for your body.
All sleepers need a supportive mattress and especially back and stomach sleepers. Side sleepers also need support to align the spine and neck while they sleep. These mattresses are above average when it comes to support. However, some have had reported some issues so if you are heavier than most, make sure to take a harder look.
Most agree with the edge support of these mattresses. But, some heavier customers may experience some dipping close to the edges.
These mattresses get mixed reviews from customers on lasting comfort. We all want a mattress that stays just as cozy in 10 years as it feels now, but sadly, not all will support you for the long term. If you are thinking about buying a mattress that has mixed feelings on durability, do one last review of the return and warranty policies so you are secure in your purchase.
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!
Purchased Sleepys king size over a month ago. I have never had a more consistent quality sleep. I work a lot and have soreness in my back and legs (not injury pains) and used to only sleep around 5 1/2 - 6 hours a night. I sleep soundly now with the Sleepys mattress. I would recommend this to any and everyone that's looking for a new mattress. First time I've slept past 9am in many years.View More Reviews
I bought this mattress 3 weeks ago and I have Fibromyalgia, arthritis, severe back pain, chronic pain for the last 18 years. Every mattress I had before caused some sort of pain, even with memory foam mattress toppers. I decided to try the Sleepy's Essential 8" Memory foam mattress and I'm so happy I did, I'm SO pleased with this mattress!!! it doesnt make you feel hot and it doesnt sag when you lay down on it; is a firm feel but its very comfortable. The first night I slept on this mattress I slept through the night and that is something I could never so before. My sleep is so much better since I purchased this mattress and I recommend this to any one who suffers from back pain or similar problems that I have. It was worth every cent I paid for it! Thank you so much Mattress Firm!
I purchased this mattress and have been satisfied ever since. I love the feeling of sleeping on a firm mattress with a little cushion so this was perfect. I liked sleeping on the floor as a child because of the firmness, now I have comfort and firmness.
I was surprised when they delivered it how it was compressed , After 2 hours of expanding it was ready to try in the comfort of our own home . It sits a lot lower than on the old matters ( felt like you would fall off a mountain with that one ) So far a delight to sleep on an we picked it out ourselves .
Sleeping so much better. Happy to have a great mattress.
I slept on this for about 2 wk and a half. First 2 wk smelled, so I tried to air it out the first couple of days by taking off the cover/ wash/ keep upright w/ windows open, ventilate etc. After 2wk the smell is alright. I like mine firm, so this one is okay. I prefer slightly more firm but overall this one is alright.
Bought it for my son, he is very happy with it and sleeps well at night.
The price quality and service can't be beat great job Mattress Firm
I brought this for my I Uncle who has mobility issues. After he got use to it, he was able to get in and out without any problem.
I received my bed on Jan. 25th, 2018 and it's just absolutely great.
Is firm firm firm I love it!!! Just like I expected thank you so much
My first night on this amazing mattress. I love my bed.
Bed is soft but does not return to it's original position well. I've been sleeping on one side and after about a week or two there is a noticeable difference in height between the side I sleep on and the other one.
I sleep so well on this mattress and that’s what count. Love this, love love love!
My wife and I live the new mattress and the price was right...thank you
I’m very happy with my new Bed! The pillow top is great balance between plush and firm mattress!!
Just got our bed today and i love it my wife and i both have bad backs and its perfect
This is the best mattress, hands down!! I did a lot of research and took a lot of different quizzes to figure out what kind of mattress works best for me, and this one came out on top. I have back problems and since I got this mattress last week, I haven't been any! It is plush yet firm and oh so comfortable. I also bought a mattress pad that has made sleeping so good. I 100% recommend this mattress to anyone and everyone!
I bought this mattress on 5/14/18 for $249.00 and I hate it! It is as stiff as a board and makes so much noise that even when the dog moves, It rests on a very expensive box spring that has never creaked before. I cannot exchange it without incurring another $100.00 fee. I have a back and neck ache that I did not have before sleeping on this horrible product.
My dad bought this mattress for my younger brother. He is very tall and is very active, he loves it! It's so supportive, not too firm or too soft, and very comfortable! I am surprised at how great the quality is for the price.
This is the first time i have bought this kind a Mattress, I had my doubts since my youngest daughter have one like this, i have two back surgery’s my doctor recommended me a firm mattress and said this is garbage mattress i said let me try it. I can’t be more happy! I got ut with the adjustable base, the best purchase ever. 5 days and 25more to go for. Since it takes 30days for your body to get used to a new bed.
The store clerk said we would not regret it if we went with our first choice on a firmer option. The queen arrived in a skinny rectangular box that we thought was the frame because it was so compact. Amazingly, over the next hour, it transformed from a pancake into a thick and luxurious mattress. We got the protective casing which makes me feel 10x better during everyday use that we will never have a problem with our warranty. So far, the bed is exactly what I wanted. When I go to sleep, I have a tremendous amount of support with enough give to make an indent where my body naturally curves. I'm about 125lb, and my husband is about 225. He says his indents do not as quickly rise when he changes positions, so it takes a minute until his side of the bed fills back in. It's only been a month, but I have confidence we are going to love and keep this bed for many years. I highly recommend the base with the header and footer rise. We always sleep with it flat, but the few minutes in an elevated foot/head position really relieve back tension. Thanks for a high quality product!! The bed is also beautifully stitched. I would come back. The deals at mattress firm are competitive for the quality you receive.
I am sleeping so much better, it is cooler I am not turning as much , I find my self wanting to get in bed n useing the feet n head posture in stead of siting up in frount of the T v in family room get to to work on my I pad ,
We slept on this bed for over two months and it just did not soften up as much as we had hoped, really barely at all. It is a very firm mattress but is still comfortable to sleep on though it just causes back pain for me and my partner. The cooling is great but make sure you have breathable sheets or it will be just as hot as any other bed. If you are looking for a firm memory foam this is great, just dont expect it to get much softer than what you get the first day.
bought this weeks ago and now my son is getting a good nights sleep
I have had this mattress for a few weeks ago and I am glad I went with the Sleepy's cool. It is a bit on the firmer side but this is what I like. For the price you can not go wrong. They had a special and I got a free adjustable frame with my purchase and I could not be more pleased.
I’ve been sleeping on the twin version of this mattress exclusively since it was delivered on 4/23/18. Some background: I had been experiencing a lot of morning mid-back and rib pain on my old mattress, and was not sleeping well. I am a mid-50s insomniac woman. I tried several models in the store, including Tulo and Serta iComfort memory foam, and chose this one due to its thickness, beefy feel and comfort during the 15 minutes or so of testing. Although it felt firmer than my preference, I figured it would be a good option for my back pain, and I decided to give it a try. I did not think to purchase a new foundation (“box spring”) at the time.
I just purchased in store 3 days ago and I love the cool mattress temperature and the fact of it having no springs. It's plush firm like cuddles your body I have a knee injury and in the last 3 days of sleeping on this my knee has felt better.also I don't need a bunch of pillows anymore my back feels great .. I will never go back to springs. This is a great mattress Try it...
I bought this mattress a week ago. I have had Simmons and Serra inter-spring beds up until now. We tried it in the showroom and were hesitant as it was very firm but since it sort of confirmed to our body and the price was right we thought we would give it a try. I can say now that it is taking us a bit to get used to this type of bed but are overall very happy with it and are confident that over time it will soften up a bit. It is a well constructed bd and we are happy with our purchase
I am so pleased with this mattress the best thing I like about it is that it is so solid that you can't feel the next person moving on the bed when they toss and turn or get up or lay down it's very comfortable and just what I needed
I bought this a couple months ago and love it! I sleep through the night!
Have slept in this mattress for 5 nights and was hoping I would get used to the firmness but unfortunately neither my husband or I sleep well in it. My children had a foam mattress and love it so we thought we would give it a try in our new beach condo. They obviously purchased something softer because this is extremely firm. Wake up each morning with a back ache. Going to call about exchanging it.
We exchanged a tulo for this mattress and were very satisfied. My wife sleeps better that she has for years. thank you.
I'm very happy with my purchase, the service and everything was great! I wouldn't trade my mattress for anything, and at unbelievable, affordable price, highly recommend them!
I love my new mattress couldnt be happier only if i could stay in bed longer
We bought our mattress a month ago and it was our best purchase ever. Can't wait to climb in bed every night. No aches or pains ever since our mattress was delivered. We give it a 5 star rating.
I had this mattress for about a month and although I love the feel of the mattress it seems hotter than a normalization
Value was important to us and this mattress was a great purchase.
You wouldn't think it but my old mattress was killing me! After one night of sleep on this mattress my left shoulder and back had no pain. Which hasn't been the case for almost a year. I thought I was just getting old turns out is was my bed! Sleepy's cool mattress me and my wife thank you its been over a month and we can't say enough to thank you for such a great Mattress and for relieving what felt like years of pain. I do have one question for you do you make pillows?
Too early to tell ... so far I like it. No recommendations yet.
