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!
I’ve bought two of these mattresses. Excellent quality, super comfortable, and absolutely no chemical smell. I’ve spent 6 months researching mattresses with concerns about health, comfort, and quality. I finally decided on the organic latex. I found this to be the cheapest site to buy from (despite the fact that I live in Canada). We are planning on buying 3 more, as we are a family of 6. It’s the only mattress our family will ever use and the only one I’d recommend without hesitation.View More Reviews
We purchased a full mattress for our guest room. This company is the best! Excellent customer service, shipping, packing. Mattress is super comfortable and has gotten rave reviews so far.
We purchased our dream vacation home, so we wanted our dream bed. We purchased the exact same king set up that we have at home. It’s so comfortable, we just love our bed and now there’s no getting used to a different mattress. Shipping is very quick, and easy. We also purchased the new Roma Mattress for our guest room. Our first guest said it was great!! I am constantly recommending SleepEz to anyone who will listen. Thanks SleepEz!!
Best Ever with the option to change firmness once you order it. Your never stuck with what you thought you wanted. Great customer service, friendly, helpful people who only want to give you a great mattress buying experience! Larry Kitchens in Norfolk Virginia
This mattress system is truly amazingly comfortable. As someone who had no problems sleeping on my 20-year old mattress, I can attest this is incomparable and that I sleep even better. Before I would have a few minutes before falling asleep, now I am out almost immediately. Combined with silk and linen bedding, it is such a luxury and comfort. The mattress came in three boxes and was simple to set up. The video on the website is helpful. Basically, you spread the organic cotton and wool cover on your bed and assemble the mattress components based on your preferences. The system is very versatile, with different layers and firmness can be combined. In addition, for queen size and larger, each half of the mattress can be different. It is a really amazing experience to sleep on this mattress. I also got full bedding and several pillows made of the same awesome latex. I fully, highly recommend it from personal experience.
First time user of latex mattresses. So far this has been a great experience. Sleep EZ Customer service is great too! Those guys will work with you in resolving any issues and their recommendations are noteworthy as well.
I love my new mattress! No more back pain.
I bought 13-in Natural Latex Mattress with All Talalay layers (firm, medium, medium, soft). Originally, I was afraid that it's going to be too soft. I was so glad I decided to order it! It is soft enough but you are not sinking in it. Love it! My husband loves it too. I sleep in all positions (on my back, sides, and abdomen). Delivery was fast. Packaging was good and secure. Took little bit time to unpack it, but no problems with it. It comes with free sheets, pillows, and mattress cover. No smell, no defects. Easy to put layers together. Thank you, SleepEZ!
My boyfriend bought this mattress last year because I complaining of having back pains. I have not had any back pains since sleeping on this mattress. I just purchased my house and the minute I got my keys, I called and ordered another of the same mattress for my new home. Now we have the same mattress is both our houses. I would buy this mattress for my guest room but I am afraid they will nit want to leave. Thanks Sleepez Am really sleepin E Z Z Z Z!! (Sleeping easy)
Haven’t slept this well in years. Forgot what sleeping well felt like
So far I like it
Excellent customer service! We called during a sale and got a recorded message saying that they would call us back if we left our number and a brief message and they called back promptly and were extremely knowledgeable and friendly. Then when we called in our actual order, the customer service representative couldn't have been any more pleasant (I'm sorry, I can't remember her name!) and was very helpful with some more questions that we thought of. First rate outfit all the way, would definitely do business with them again!
The mattress is very comfortable. I also like the ability to change the layers to adjust firmness.
A very comfortable mattress. Very professional and knowledgeable sales personnel. With the split mattress it is very easy to set up different firmness levels for his and her sides.
Our previous mattress was a Simmons Beauty Rest with pillowtop. What started out as a mattress we liked, became a mattress we loathed. Lots of sleepless nights and pain in the morning. Our online hunt began for the perfect replacement. I first started reviewing memory foam but after a lot of research, I decided against it. I am so glad I did my homework. My search brought me to an unbiased reviews site sleeplikethedead.com. I discovered latex was the way to go for me. I compared several mattress stores recommended on the site and really liked what Sleep EZ had to offer. The purchase was seamless. I received a phonecall after I submitted my online order and was even more impressed with their customer service. All of my questions were answered and then some. My mattress arrived about 5 days after ordering. Assembly was a breeze. I was expecting to have an adjustment period but I instead the pain I was experiencing with my old mattress immediately went away. I sleep cool and comfortable every night. Don't hesitate to make the switch and go with Sleep EZ! They are incredible!
Today is day #25. So far, so good. I'm almost 100% sure that we won't sent it back, even if we decide it's not for us. You see, the worst of this mattress is far superior to the old Sleep Number we got rid of! Seriously, I expected to like it, but my husband likes it too. The jury is still out on whether I'll swap the soft top layer for a medium one, but probably not.
I have artificial hips, shoulders, and one knee. The bed is so nice and soft and there are no pressure points. Best nights sleep I have every had
hips don’t hurt
Great (incredibly great) customer service. Product arrived on time and as expected. Was easy to assemble. Boxes were even labeled. Only room for improvement that I could find was exploring use of a perforated plastic or adding a pull tab assist in opening the foam wraps. Either way, would certainly order again and already recommend to friends. Thanks.
My husband and I have had a sleep ez for 8 years and love it. We bought one for each of our children. The only problem is we are so spoiled it is hard to spend the night anywhere else but home.
We purchased an organic all-Talalay mattress based on our extensive online research. Our mattress arrived timely. It's easy to set up, comfortable beyond words, and has helped alleviate my partner's chronic back pain. Buy with confidence from this company; you won't regret it!
After 3 months my whife and I adjusted well to this mattress configuration. The support is excellent because the mattress normalize the body density and weight distribution in such a way that it countours the body profile in both side and back position; thus eliminating pressure points and spinal misalignment. The key is to align the neck during sleep patterns and the pillow supplied does just that. Other nicities include the adjustable bed that accomodate snore and other luxerious positioning. I'm well pleased with this design. Thx Langsy
Very pleased with my mattresses. And very, very pleased with the company. Easy to get a hold of real people there. Very helpful with all my questions. And went beyond the status quo to make sure I was satisfied. Thanks!
With our old mattress both my wife and I would both wake up a little stiff most mornings. With our new mattress that is no longer the case! We've been sleeping on it for about a month now. We customized each side, with one having a soft top layer and one medium. We experimented with switching sides and found out that the customization was definitely worth it because we both slept better on the side we thought would be the best firmness for our sleep position. We're well pleased with our purchase!
This is our second latex bed. We bought the king size to replace a queen bed. We will never go back to a traditional mattress. It is a little more work to put a king size mattress together due to the size, but worth it. Great communication from Sleep EZ regarding shipping. Thank you!
Bought this for the holidays. Had many very sensitive family members coming who can not tolerate non-organic mattresses. It was so well received that I may eventually move the mattress to the master bedroom!! Was very quick to receive. Arrived in pristine condition. Needs two to put it together, but its easy with four hands. So satisfied!!
We absolutely love our new mattress. We love the split side option! My husband and I needed different firmness levels and this was the perfect way to do it. The layer exchange process was smooth.
Great experience from ordering, delivery, set up instructions and phone support. Would not hesitate to recommend sleepez to anyone looking for a quality latex mattress for fair price
I have rheumatoid arthritis . Husband has lumbar DJD. it is the best bed ever! I have no pain. Husband's 90% better. It's on a adjustable base. GET IT!
So we were very skeptical to buy the first one. We lived in texas the showroom was in Phoenix we couldn't see it and we were hesitant to buy something we couldnt see or feel. Our son had allergies badly and all my research showed these didn't have that kinda problem and didn't off gas and other things. So we bought hte first one for his benefit. Its like a mattress from a 5 star hotel. We bought this config in case your wondering - Xfirm, Firm, and Medium. We liked it so much we changed our king bed as well to the same thing - those two are now 3 years old, we just bought another bed to replace our last remaining regular mattress. The only complaint if I had one is that there is a little bit of compression over three years where we mostly lay. Not super noticiable or anything but something, for that reason we rotate it (not flip) every 8-12 months. But other then that its PERFECT! we have a hard time sleeping on any other beds now!
My wife and I are sleeping longer and more sound than we have in a long time! Great innovation to be able to set up the firmness level of each side of the bed. We're both happy with what we chose!
I am chemically sensitive (but not allergic to latex). This was the perfect fit for me. Staff also very helpful.
Relieved a lot of back issues.. I’m very happy with my ourchase
We purchased 2 mattresses for a folding platform frame to use for guests. They are as comfortable as the 3 layer mattresses we purchased from SleepEZ 8 years ago. They are so comfortable that we wouldn't consider any other brand. The best thing is that you can move the mattress easily, because it comes in layers. I stacked the 2 new mattresses on top of an existing SleepEZ bed, and now our guests can sleep in a regular bed.
I love it 😍
Really, happy with my new mattress. Custermer service before the sale was excellent.
Setup was a little daunting at first because I’ve never built a bed, but it actually was quite easy! Very comfortable beds and very quiet when moving around on them. Great support from the team at EZ... I recommend the EZ bases and they also went together easy without tools!
I am chemically sensitive and have finally found a bed that has no toxic smell. I am quite happy and comfortable in my natural latex bed. The phone associates were friendly and so helpful. One slip up with an item not received was quickly remedied. So very satisfied with my bed and this company!
