My husband and I absolutely love our new Endy mattress. I don’t think we have ever slept so well. Delivery was quick and set up was easy. We would recommend this bed highly to anyone looking for a medium-firm mattress.....Support Canadian business!!View More Reviews
Best bed ever! Perfectly fills the contours of my body, allowing my muscles to relax and wake up rejuvenated. The best therapeutic bed I have tried out.
My hubby and I weren’t sure what to expect when buying an endy. The customer service has been great and the mattress is very comfortable. We are sleeping like babies! ❤️
We love our new mattress! No more tossing and turning all night. I have issues with my shoulder and this has helped me sleep on that side. My husband has restless leg syndrome and this has lessened it and when it does happen, it's not waking me up anymore as I can't feel him moving around.
I love my new mattress! And the order/delivery was stress free. Thank you Endy!
Exactly as advertised! Love it. No more sore hips. Thank you 😊
love my Endy!
The only thing getting us out of our bed in the morning is the kids. We love our Endy.
I love my new Endy mattress, I have not slept this well in a long time.
BEST BED EVER!!!!!!
I bought this for my 3 year old daughter. She slepts so well on it and called it her ‘cloud’ bed. It has been wonderful cuddling on this mattress.. hard to get out. The most amazing part was that I ordered this mattress on a Thursday night and found it on my doorstep Sat afternoon!
Awesome!!! Highly recommend this mattress. Don’t hesitate buy this mattress!!!
Perfect for our guest room and so affordable!
Our old mattress was an 11 yrs old, lumpy pillow top. We upgraded to a king Endy when our daughter was 2 weeks old and even with a newborn we have had the best sleep ever! Sure I wake up for her, but otherwise I am so impressed with how comfortable this mattress. I’m dreading one thing about our upcoming vacation and that is having to sleep on a mattress that won’t compare. Super fast shipping for an amazing product. Win, win, win!
Great sleep & stay warm after you get up and come back to bed
Sleeping on angels.
My husband loves it, and I am getting it to it
I took a chance buying it and waiting for my body to adapt. It is a little too firm for my liking so I give 3 stars instead of 4. Not my type. It is good only to sleep on my back so I'm kind of using it to force me to do it. I'll probably return it.
The mattress is way to soft for me.
Love love love our Endy. Both of of us have back issues and trouble sleeping, But all issues are improved....feels like we we hit the jackpot! We highly recommend!
I am in love with this mattress! Takes a few nights to get used to it as they say, but after that it is the most comfortable mattress I have ever slept on! And the mattress was delivered in 2-3 days after ordering! Amazing company!
I was hesitant to replace my bed, but after sleeping on an Endy Mattress I can’t believe I didn’t do it years ago.
Can not believe that I could fall in love again, but I did. Her name is Endy. 😉 Seriously though; this is the best money we ever spent. Highly recommend one to anyone who is having sleepless nights.
We are loving our new Endy bed
Finally I can get through the night without my shoulders killing me
This is the best mattress I've ever purchased, it takes a good week to get used to. I'm having some of the best sleeps I've ever had.
It’s been 3 weeks now and we’re really happy with our Endy mattress and pillows! Everything about the service has been great!
super comfortable, just the right about of squishiness
With my old mattress I get up in the morning having back pains. A week after using Endy I dont feel it anymore! I love our Endy!
Bed is so comfy!
Great mattress, great customer service. Would definitely recommend!
This was an the Best company to deal with. Easiest mattress ever to install, and rave reviews from our guests! I tell everyone looking for a new mattress how amazing the whole process was, how comfortable it is. Love Love it!! The only negative may be that it's a little "too" comfortable for the "guest" room...lol
I just thought aging brought sleepless nights but since I received your mattress less than two weeks ago, I have been sleeping eight hours a night after decades of thinking that I could only sleep about five. I wake up feeling that all my vertebras are in place too. I am so grateful.
So far I love it. Never slept better. Back pain gone.
Both my wife and I were skeptical and were worried that one of us would like it and the other wouldn’t. After 4 weeks we both agree it’s the best mattress we’ve ever had. It’s ruined hotel mattresses, nothing is as comfortable as our Endy.
It's been a month now, sleeping better than ever. Thanx Endy.
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!
