Most folks are still comfy in their mattress after 5 years, but some who are heavy or use their mattress above average will find that their mattress is not as durable.
I cannot rave about this mattress enough -- very comfortable, non-toxic materials I can feel good about (and I am very picky about everything I buy in terms of toxicity), and what a total STEAL! I had been searching for mattresses for ages, and I could not find anything I wanted for a price I could afford until I came across this one. No off-gassing, but there is a very faint, not-at-all-unpleasant, earthy smell to it. And it was delivered very fast, way before the promised time frame. Lastly, the mattress was not nearly as uncomfortably hard/firm as some of the reviews indicated. I actually wish I had not bought the expensive latex topper I already purchased elsewhere, because it really doesn't even need it. I was a little nervous about buying a mattress online, but I am SO happy with this purchase.View More Reviews
My wife is a Naturopathic Doctor and understands the importance of a natural mattress and insisted we buy one for my daughter when we moved her out of her crib. I was hesitant since these are so expensive, but she explained that sleeping on a mattress that is not natural means that her face is pressed up against chemicals and toxic off-gassing for an entire night. This was a huge concern so we searched high and low for a high quality natural mattress that would also provide her with a good night's sleep. We went to a local store that specialized in organic mattresses and could not find anything that felt good (they felt flimsy) and they were all so expensive. I decided to search online to see if I could find something and luckily I found the Echo Mattress.
We purchased the single sided Echo Mattress for my little girl and we absolutely LOVE it. It is super clean, no smells at all, and very comfortable. It came packaged rolled up and was super easy to bring upstairs and unroll onto her bed.
Now when I read my little girl bedtime stories I end up staying in bed with her a bit longer than I need to so I can enjoy her comfortable bed. I was actually enjoying my little girl's mattress better than my own so we decided to buy a King Size double sided version of this mattress for my own bed.
This is an incredible bed an a wonderful price and the customer service in this place is amazing too!
When I started waking up with back pain on my 8 year old Beautyrest mattress, I knew it was time to get a replacement. I wanted a 'natural' mattress that was free of flame-retardants and off-gassing chemicals, but most of them were way out of my price range. I found this one on Amazon and read all the reviews. Something to note: at the time of this writing, there are currently 18 reviews with an average 4 1/2 star rating. However, half of those reviewers specifically say that they purchased this mattress for a young child so they are not reviewing it from an adult's comfort perspective. I'm going to tell you right now, this mattress is firm. Very firm. Another reviewer likened it to sleeping on a bed of rocks, which is not far off. I would say it's more like sleeping on a carpeted floor. When I first started sleeping on it, I was very disappointed--it was so uncomfortable. I should add that I have a 2 inch latex topper AND a featherbed on top of it, and it's still ridiculously firm. However, after sleeping on it for seven weeks, I have gotten used to it. I am no longer waking up with back pain and I'm not breathing in toxic chemicals. Taking into consideration price, convenience (free ship/rolled up), and natural components, I would say that I am happy with the purchase. Just know that you're going to have to put some sort of topper on this mattress--I can't imagine any adult being able to sleep on this with no cushion.
The mattress arrived quickly and in good condition. We did not have any problem with the firmness, and thought it was comfortable support. My problem was with the mattress fibers/ stuffing. We let it air out for a week before putting in on the bed. Although my spouse did not notice any smell, the mattress did give me a stuffy nose every time I laid in it for about a month, even after changing out the mattress pad and sheets. This finally went away after a few weeks and I am able to enjoy the mattress now.
We were looking for a healthy alternative to our other mattress that wouldn't break the bank and would be better on our backs. We had looked at other organic mattress that were 6 times this cost so when I found this one I was estatic. This mattress has far exceeded our expectations. It is so comfortable and we don't wake up in the morning with terrible neck and back pain. Some people have complained about how hard it is, however we never experienced that. I do enjoy sleeping on the ground from time to time as it helps my back feel better so I am used to firm sleeping spaces. At first, when you open it and unroll it or does have a strong wool smell but it's nothing obnoxious and it does go away in a couple days. We have been sleeping on this mattress now for a couple months and have felt the improvement and I love knowing there's no off gassing and I sleep easier. I would highly recommend this product for anyone looking for a more budget friendly organic mattress!
I really, really wanted to like this mattress. We are very careful with the products we buy, to make sure everything is healthy and get the best for ourselves and our kids. I got this mattress in King for myself and husband, and 2 Twins for my kids. I knew it was going to be firm, but damn! It's just not comfortable. I wanted to like it, I really did- tried everything, spent more money on toppers than I ever imagined I would. I got a very fluffy lofty topper, it didn't help. I got a wool topper, still nothing. I had a firm before, but this mattress is TOO firm, I sleep on my side and have curves, it just puts pressure on my joints. Now I'm stuck and unhappy. The kids are light weight, and I got them toppers too for added comfort, but due to how they sleep- it seems to be ok for them. As for me, I'm wishing we didn't get rid of our memory foam mattress which was a lot more comfortable. We only got rid of it because we wanted to clear the house of toxins. I really, really miss that mattress. Can't afford another topper to try, or a new mattress at this time.
too firm for our taste
Like it but cant get rid of smell for month. Waiting for summer to put it on a direct sun again
What can I say, I LOVE this mattress ! It's firm without being hard.
AMAZING. This mattress came in a roll and so was really easy to maneuver onto the bed and then cut open. It is soo comfortable our daughter loves it.
I did not realize when I purchased this mattress that it is only 'one sided' but unfortunately it is and it is extremely hard. I simply would not purchase another one like this.
I don't write reviews, but we bought this mattress for our daughter and she has slept so soundly on it! Knowing what we do about off gassing and what conventional mattresses do to our bodies, we knew we had to go with this company and ultimately this mattress! Thanks again for your stellar product!
I was a little concerned about all of the reports of the smell of the mattress. When we unpacked it I didn't smell anything but when I put my nose right against the mattress and inhaled I could smell a very tiny smell that my son said reminded him of Play doh. I think it's actually the smell of the plastic that the mattress came in. If I had not been looking for the smell I would not have noticed anything at all.
This was just delivered today so I will update later. The box was quite beat up, but the mattress inside was clean (wrapped in plastic). Upon opening and unrolling there was no chemical smell: one person said 'it smells like granola' and another person said 'it smells healthy'. Three adults (of very different sizes and weights) each lay down on it (separately lol) and each found it comfortable. It is medium firmness, not hard.
most comfortable bed in our house. my father in law now kicks my son out of his bed when he visits
This is the most comfortable mattress I remember ever sleeping on. I was sure after reading previous reviews that I would need to purchase a topper to make it more comfortable, but I love it just the way it is. I sleep better than I have in years.
My spouse and I love this mattress. We've had it for about 5 months now and sleep very well on it. It's not too firm but firm enough that it won't give you back problems. It did smell a bit like wool or barn when we first got it but too the mattress' defense, I was in my first trimester of pregnancy so everything smelled to me. I aired it out in the sun for two days as the company advised and it really did help. I feel really good knowing that I sleep on a healthy mattress. I plan on buying another one.
We were looking for an organic mattress, and this one was an excellent price. That being the case, I was not expecting to find such high quality! I am very happy with this mattress! It is very firm, which I like because it has really helped my children's back issues to be sleeping on a firm mattress, yet it is still comfortable. It seems sturdy, well-made, and I have high hopes it will hold up well as my children grow up. It had no odors other than the cardboard and exterior packaging, arrived quickly and was packed all rolled-up- so it was very compact and relatively easy to transport, considering it is a mattress! I was so pleased with the purchase of the first mattress for my son that we have purchased a second for my littlest, who sleeps much better now that she is on this mattress, interestingly enough. I highly recommend this mattress and will be purchasing a third mattress after the baby on the way is big enough for a bed. Many thanks to the company for offering a quality product that is free from chemicals, well-made, and very reasonably priced.
We purchased two of these mattresses in the twin size for our four year olds. They are not super comfortable but our children seem to like them. I probably wouldn't buy them again but time will tell how well they hold up.
Matress comes rolled up and pops out like a roll of biscuits !!! Places a matress topper on it and it is money !!! Very happy with the purchase
Love it. I bought another after the first one came in, very comfortable!
This mattress is better than I expected!
t smells gross, with a really strong chemical smell that comes through the bedding even six months later. I am worried about having my child sleep on it and am considering throwing it out. I don't know what the smell is but it can't be anything good. I should have known that the price was too good to be true.
I needed a mattress that wouldn't make me swell up from all the chemicals on it. So many were expensive or didn't look very comfortable. I eventually took my chances on this one. I was concerned about the mention of smell because I am very sensitive to smells. I even called the company to ask if they could air the mattress out for a few days for me. I wasn't patient enough to wait the first time for them to answer because I needed a mattress soon but an unfortunate event turned into a fortunate result. When the bed arrived, FedEx had an accident with the package and the bed was no longer sealed inside the packaging. I called the company and sent them pictures. I called FedEx and they picked up the mattress. The mattress company remembered me and before getting the mattress back, they started airing a mattress out for the 3 days that other reviews mentioned. They sent the mattress to me before even getting the mattress back. BTW, the smell reminds me of Cheerios in case you wonder what it smells like. This mattress was just made right before it was sent to me so it is very understandable I could still smell a little of the materials. I have had it for less than a month and I sleep well. I don't wake up swollen. I am so happy about that. I have arthritis and I wake up stiff most of the time with the old mattress. I barely ever have problems with this new mattress. I got organic sheets too. The bed is firm, very firm. I like soft beds but the firmness doesn't bother me at all. The bed is wool and cotton. There isn't foam so there isn't much to make it fluffy but I figured if I had a problem, I would get a mattress topper. I don't need one though. I am quite comfy in this bed. This is a great mattress with great employees. I would highly recommend buying one.
The bed is perfect medium firm and very comfortable. It does not have any odors and delivery was fast. Highly recommend.
I switched to this mattress after sleeping on a premium organic latex mattress from another company that cost nearly $3000 and sank terribly in the middle after only a handful of years of use. The Natural Escape feels extremely high-end in its materials and construction, and I adore the perfect medium-firm density. Such a reasonable price point for the unquestionable quality (not to mention the fab company philosophy!) I now own two�one for me and one for my toddler son.
Very comfortable without the sunk in feeling of memory foam, great edge support and I didn't feel hot like with some mattresses. Outstanding customer support that handled everything quickly and professionally.
This is the most comfortable mattress I�ve ever owned! Customer service was very helpful and nice, and it didn�t smell at all when I unpacked it. Would highly recommend!
I’m chemically sensitive and have bought three of these mattresses in the last two years. I love them.
We’ve only been using it a week but I’m happy so far. My hip pain more or less went away after the first night!
My family and I were in the market for a non-toxic mattress. We had been doing a lot of research because we have a new baby. We compared options and we came across Mygreen. We were skeptical about a mail ordered mattress. But, we have been pleasantly surprised by this wonderful mattress. It has a lower price point than other natural options. No adhesives. Non-toxic materials. It is very comfortable. It has very faint earthy smell to it. I will recommend this company to all of my mommy friends and family. We love it! Thank you for a healthy nights rest!!
This is the best mattress I have ever owned and has given me the best sleep of life over the past three years (and still going strong). My wife and I are about to buy our second for a guest room.
Love this mattress. I salute with the middle of five, the other chemical bed mattress companies along with the satanic government agencies that mandate the use of chemical fire retardants. Because you never know when you might spontaneously combust into flames during your sleep. In any case, this mattress is amazing. And not being forced to sleep on cancer causing chemicals is well worth the price.
I researched organic mattresses for weeks prior to purchase. My Green Mattress was the Best Buy based on price and comfort for combo sleepers like my husband and I. We also bought the topper for additional softness. We are very happy with purchase. Highly recommend.
Our whole family loves how soft and firm this is, depending on your perspective! We even changed over from memory foam topping over our last bed, and found this mattress to be a downright good quality bed. I personally love the intention of the company and the �cleaner� product compared to other beds/companies! Would definitely buy again!
Nice mattress! We like that the quality and safe materials this mattress is made of. There were no smells upon opening the box. The price isn�t cheap, but we are happy with the product. It is firm, but our backs feel good!
We've been sleeping on this mattress for a couple of weeks or so. My spouse says it's "fine", and a great improvement over our previous, worn-out foam pad. I've had serious back troubles all my adult life, and am utterly delighted with it so far. I was waking up every morning with a lot of back pain, all gone now. I really hope this mattress continues to work this well!
My husband and I absolutely love this mattress! We love how it feels but most importantly we love the quality of it. We sleep better just knowing it does not contain harmful materials and its all natural. Great costumer service and fast delivery. Worth every penny!
Huge fan of this mattress! Easy to put on my frame and fits perfectly! I love how comfy it is!
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!
