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!
I was a little hesitant in buying this mattress not knowing how it would feel. But I went for it and am now recovering and sleeping the best I ever had! It’s a must buy!View More Reviews
We can’t say enough good things about our purchase! We both sleep great. And best part...no more lower back pain for me.
Absolute best mattress and pillows I’ve ever experienced (68 years)
I was a little skeptical at first, because it came in a box. Don’t be fool. Best decision ever. Set Up: Super easy. Be careful when cutting the bag so that you don’t cut the mattress. I just wished it gave a hint as to “this side up.” Support and Comfort: Right Firmness. The mattress targets certain pressure points on the body. I did an 18-mile run, laid in my bed and noticed how relaxed my feet were. My recovery time was seamless. Cost: It is pricey, but it is so worth it if your workouts are intense throughout the week. There is an option to purchase the mattress through credit and pay it off by installments Sleeping pattern: Wow! I have been able to sleep my full 7-hrs. Rest is key.
I have to say was very sceptical but it has been awesome
It had been at least 12-years since I’d purchased new mattress, so looking for a new with all these different types of mattresses was going to be tough! After extensive research and reading reviews; I bought my performasleep King mattress! Well needless to say it didn’t disappoint. Great mattress and from the moment I laid on it; I felt my body just starting mold into the mattress with all support it needed still!
This mattress has brought sanity and sweet, sweet slumber to our lives. We feel the need and urge to tell all our family and friends about it. It has been a blessing for sure!
I haven't felt so happy about going to sleep before my matress arrived. Help my lower back pain significantly. Very happy.
Absolutely the best sleep I’ve had in my life, through my marine corps career and now a veteran with back shoulder knee and other problems I’ve found a bed at least for now which satisfies my needs. Excellent job.
I love this bed. Such better sleep at night. I should have gotten pillows to match!
I've been sleeping on my queen size mattress for a week now and have been extremely happy. I wake up well rested and feel refreshed. The perfect combination of firmness and comfort. Great bed!
The mattress has changed the quality of sleep for both me and my life. We both feel like we have better quality sleep
I bought this with some skepticism because of all of the differing models out there. I have used this for two weeks now and its great. It shows me just how much I needed a new mattress. Getting great sleep and not waking up with a sore lower back anymore. Worth the investment . JH
Cannot until it arrives
Best night's sleep in years!!!
First time sleeping in a foam mattress. I thought it would feel mushy and hot. But its actually comfortably firm but not too firm and not too squishy. I also thought it would be hot. It feels comfortable. It doesnt get too hot or too cold. Back feels better too!
We've been sleeping on the mattress for about a week now and if it holds it's current firmness I will be very pleased with it. It's a really good combination of softness and firmness.
Great products and great service!
Extremelly happy with my new mattress. So comfortable and no back pain. Love it!
I had problem with my old mattress and would wake up with lower back pain all the time. This mattress fixes that problem. I’ve been sleeping great since I’ve bought it and have not been nearly as tired in the morning when I wake up
We were on a search for a decent bed that was affordable for a good year. It came down to choosing a box mattress but it's so difficult choosing a brand! Ultimately we choose this mattress because my wife competes in Crossfit competitions and Spartan races and she liked the idea of a mattress to play a role in her recovery. We are now both sleeping better at night with no tossing and turning and seem to wake up more rested.
Thank you for making an affordable quality mattress! Worth Every Penny!
I have had the bed for a couple of weeks and it has preformed as advertised.....and I am very happy with the purchase. I have had no lower back pain that I used to have after sleeping on my old conventional mattress.
I’ve never slept Harder or Better on this thing! I used to snooze for hour or two every morning, now I’m rested, rejuvenated and excited to get up at my first alarm and get to my morning workout.
We love this mattress. It shipped quickly, easily set up, and sleeps great. Highly recommend!
We received our Performa sleep mattress a couple weeks ago and so far we are in love!!
Been sleeping on a king size for a week now, I’m a severe Sleep Apnea case and haven’t had a dream I could remember without wearing a CPAP for a very long time. That changed last week when I got a Performa...I’ve constantly woke up this week and remembered having vivid dreams. It’s kind of nice knowing I’m actually falling into a state of better rest. Getting back to training this month and can’t wait to see the improvement while recovering through better sleep. Seriously, considering a purchase of the pillows offered.
This is the most comfortable mattress I've ever slept on in my life. I lie down and don't want to move. This is the only bed I've ever been able to sleep on on my back. It is definitely cool. My fitted sheet feels almost cold to the touch. I haven't gotten overheated at all. I was able to carry the box to my bedroom and unpack it myself (full size) Such cool packaging! I did that in the afternoon and it was perfect at bedtime.
Noticed a big difference in my sleep the first night we got the mattress. Didn't wake up once during the night and the copper infused pad helped keep me cool all night. Can't imagine sleeping on another mattress.
For years I’ve had trouble sleeping and waking up feeling rested in the morning. I’ve been sleeping on my new PerformaSleep mattress for 9 days and I’ve already seen a drastic improvement. I wake up much more rested and without back pain. It’s been years since I’ve felt this good. Thank you PerformaSleep for an incredible product.
Bought a Queen mattress a year ago and had to buy a king because we just needed that much more amazing!
The mattress arrived very quickly and was a snap to set up. It is extremely comfortable. I am glad I made this purchase.
I purchased this bed based on reviews and not sleeping well along with waking up sore because of a crappy mattress. Now that my body has become used to the performa sleep mattress I sleep great and wake up feeling rested and never sore. Also, it was incredibly easy to unpackage and start using.
What a great bed! It exceeded my expectations!
After the first night I wondered why I had waited so long to switch to PerformaSleep! I have spent my adult life with back pain and pain in my hips from sleeping, since I've had my PerformaSleep mattress I've been pain free. I expected an adjustment period because I've spend my whole life on a traditional style spring mattress but I had zero issues adjusting and from my first night I've been sleeping better than I have for years!! And customer service, top notch. They responded to an email within hours, on the weekend!! Thank you PerformaSleep, I recommend you to everybody that will listen!!
Have had this mattress for a two weeks now and no complaints. I'm actually getting less hours of sleep but waking up more fresh. I feel it's definitely helped my recovery also.
Love my new mattress and let’s not forget the pillows!!! Best pillows ever!!! You guys are the best, you really care about your product and making you customers happy!!! 100% recommended... I’ll definitely change all the mattresses in my house...
This is not a super soft pillow top mattress. This is a mattress for an active individual, it is firm allow your muscles the time need to relax and recover. If you are used to a softer bed give this mattress a few week and you will feel the difference. Great Mattress!
Happy with my new bed
I received the pillow first, and my boyfriend instantly fell in love with it. A few days later the mattress came, and I haven’t slept this great since I can remember. It’s truly amazing. Oh and my dog and my boyfriend fight over the pillow. We definitely are very pleased with our purchase!
