One of the best mattress I have ever slept on.View More Reviews
It doesn’t gas and it stays cool! Perfect for me husband and myself!
I have had the Hyphen for over a month now and I can't relay to anyone how happy I am with it in a review. It's just a fantastic bed. Period.
Feels great and takes some getting use to but overall very happy.
Stays cold, even with multiple sheets covering it. Super comfortable and relaxing, no longer twisting and turning for that perfect spot.. Transformed my night!
My husband had been noticing on his sleep tracking device a severe lack of deep sleep. He would get an average of 30-45 minutes a night. After trying out various mattresses in stores and doing a lot of research online to find the right mattress, we found Hyphen. We've been sleeping on our very own Hyphen mattress for about 6 months and we absolutely love it! I sleep through the night (mostly, I am a mom) and my husband's sleep tracker consistently shows at least 2 hours of deep sleep.
I was hesitant to purchase a mattress online, but we decided to give it a go because of hyphens return policy. My fiancé and I are so happy we purchased this mattress. The foam contours to my body well and I no longer wake up with pain in my lower back. This mattress is the perfect medium firmness and sleeps cool. The best part... there is little to no motion transfer. I am a very light sleeper and I hardly feel when my fiancé gets into and out of bed or tosses and turns during the night. It is incredible! We love our new mattress! My parents just ordered a hyphen mattress for themselves after testing out our bed.
I've never purchased a mattress online but since I was moving and didn't have the means to transport something large this made sense. Quick delivery and packaged well this mattress isnt soft but isn't too firm. I definitely would recommend this mattress for anyone in any situation.
My husband researched mattresses and this was his recommendation. Delivery and set up were very easy (though because the box is large--we ordered a queen mattress--I would recommend two people to help move the box, especially up stairs). I did not notice any smell once I unwrapped the mattress. We placed our mattress on our existing box spring, which has worked well. It took a couple of days to get used to the mattress, but since I have slept well. (We have had our mattress for just under a month.)
My husband and I bought the King size mattress about 5 weeks ago. When we opened the plastic, within minutes it it was ready to lay on. There was no oder at all! We also purchased the mattress protector. My husband prefers a firm mattress and sleeps on his side. I like a softer mattress and sleep on my back. I researched for weeks reading hundreds of reviews from all different companies. We have always gone to mattress stores in the past and we were over it! We have spent a lot money over the years, from the traditional spring, to foam and also Select Comfort air mattress. We wanted to move from a Q to a K bed. I loved that you can sleep on the Hyphen for 90 nights. That was huge to us! We also don’t feel each other moving around or getting up which is nice. So far we like the mattress. We are happy we have the 90 nights to really get the feel for it.
We've had our mattress for a few weeks now and really like it. Would definitely recommend it.
It was super easy to set it up and so far it's been very comfy. We're happy with our new mattress.
I am a 6'6", 275 pound person who sleeps on their side and no store-bought mattress I have owned compares to the comfort provided by the Hyphen. 10/10 would recommend to anyone looking for a comfortable, sturdy mattress.
Love it!! Comfy and well made! And attractive..fit the platform bed I ordered perfectly!!!!
Very good mattress.
My fiancé and I had been sleeping on a busted old mattress for way to long, we had visited a few mattress stores with hopes of buying a new but the prices were just too high. After sleeping on my sisters Hyphen mattress, I decided to buy one! With a little holiday promo code, the price was right! The mattress is insanely comfortable - firm but soft. Who knew we'd be able to sleep so well again! We couldn't be happier!
I saw a few reviews that said to give yourself a few nights to get used to it but my boyfriend and I loved it right away! It's so comfortable and has kept me much cooler than our regular mattress this summer. Awesome value for the price! I live in Alaska and I absolutely appreciate that Hyphen even ships up here, nevertheless does it for free.
I have had some very expensive mattress' in the past but this one is great. Have had it almost a month now and my back is much better, no kinks, pain and I am walking with a straighter back. :)
We purchased this mattress to replace a very thin, very uncomfortable hospital bed mattress. Initial concern was that the Hyphen mattress would be too thick for the adjustable positions. After unpacking and allowing the bed to expand we tried the head and foot adjustments. The head raised up to my sleeping position with no trouble. The foot/leg adjustment didn't work so well without a body actually in the bed as the mattress stayed flat and shifted upward. But once you put weight on the mattress the adjustments worked well. This bed is very comfortable. It also did not sleep "hot". However, we had to put a mattress cover on the bed because we were afraid it might get stained. So the plastic mattress cover causes its own heat reflection. After one week of use I give this bed a five star rating.
It's been a month and my husband and I love our Hyphen mattress. It's firm enough that we don't feel each other move in the night but soft enough to relieve any pressure points. Couldn't be happier.
But I am a believer. I did have to put a cooling mattress pad on the top, as it did get me rather warm a few nights, but other than that I am enjoying my new mattress. And I'm still in the 100 day test period.
My husband and I wanted a mattress to go with our adjustable frame and this is perfect. I prefer a firmer mattress and for foam, I think this is about as good as it gets. We laid on a lot of mattresses and we are happy we chose Hyphen.
The new Hyphen mattress is so comfortable! Both my husband and I had a great night’s sleep. No pressure points causing discomfort; no sagging on the edge. Definitely a great buy - thanks!
Enjoying the KING- SIZE comfortable - luxurios NEW Hyphen with 20 yr guanantee .....;))
Outstanding value. I was skeptical to purchase an online mattress but took the leap with the return policy. Very comfortable mattress and exceeded my expectations.
A friend got a Hyphen and loved it, so we went to check out his mattress. It felt great, so, after dithering about buying a mattress online, I ordered. In about a week, a big, heavy box (with very helpful handles) arrived. It's not hard to muscle the rolled-up mattress out of the box and onto the box spring (I kept my old box springs, because I like a higher bed). And then the magical inflation happens (sadly, there's no satisfying inflation noise...I was hoping there would be). And then you have THE most comfortable bed. It's firm with cushion on top, is the best way I can describe it. You're supported in any position - it forms to the parts of you touching it - but doesn't leave a print behind when you move. It's not noisy -- by which I mean, when my boyfriend turns over, I don't feel it. (Also, when my cats jump up, I don't know they're there, which has taken a bit of adjustment on my part.) Two things I've noticed: there's definitely softness at the edges, so if you sit right on the edge, you feel like you might slide off. Move back 2 inches and it's all good. I also feel like it runs a little warmer than my old mattress. It's not unpleasant, and it doesn't get hot, but it's definitely warmer. I'd really recommend this mattress to people who like a firm-with-some-give mattress.
It's so much better than my last bed. Very comfortable. Helps me get to sleep faster and stay asleep longer.
This mattress if just firm enough for my 210lb frame. I don't sink into it al all and can move rather easily which is not typically the case with memory foam toppers. A full memory foam mattress is wonderful.
Bed is awesome
Same high quality as the mattress. Very comfortable.
I like the mattress, the way it looks, the way it feels. I had a good night sleep.
I was a sceptic at first but decided to give the Hyphen Mattress a try and I find the mattress very comfortable! It really does provide great relief to the usual pressure points & feels like you are floating.
We purchased this for our guest room and an incredible buy for the price. We have a posturepedic mattress in our master that I do like better, but it was 4x the price. The Hyphen mattress is a perfect balance of comfort & value - and when it is time to replace the mattress in our master, we will likely choose the Hyphen.
Excellent product and I exceptional &a speedy service.
We are loving our new Hyphen mattress. My back and neck no longer hurt when I get up in the morning. I can feel my entire body being supported, and it is not the least bit hot. I am so glad we bought this mattress!
I was skeptical at first to purchase a bed online, but have never looked back since. The bed is constructed of high quality materials and I trust in its durability given the lengthy warranty and the fact this mattress is made by a reputable SoCal bed manufacturer. During my first week of sleep on the mattress I have noticed I am sleeping cooler and waking very little during the night (confirmed by sleep tracker I wear). My wife has also expressed great support and give balance since she is a side sleeper; I sleep on my back. Everything about this bed reminds me of more expensive latex beds, exactly what I was looking for. A bed that doesn't sink, but has the support of latex/foam and sleeps cool. My only knock on this bed is support at the edges is weak, but per reviews, this seems to be an issue with many memory foam and latex beds. Finally, if you are seeking a true memory foam bed that sleeps hot and conforms to your body due to sinkage, this is NOT the bed for you. You will feel some very light motion from your partner, but that is to be expected if you have a highly responsive bed. Overall I am very satisfied with this purchase and look forward to the bed continuing to break-in with use.
very pleased so far, but may purchase a pillow top for little more comfort
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!
