Customers don't always love their mattresses, which is why finding good customer satisfaction is so essential. Versus competitiors, customers are really happy with these mattresses. Read on below for the customer reviews and mattress specifics.
Mattress support is the secret to waking up refreshed in the morning. You want something that will align your spine rather than causing you nightly pain. These mattresses do well working with your body and providing good support.
Edge support is really important for those that like to dangle their feet over the side of the mattress. These mattresses are competitive with their edge support and don't have much support degradation along the edges.
Bowling Ball & Density Tests
A popular item among readers, the bowling ball test gives a good reading on mattress firmness and evenness of support. If the mattress doesn't provide even support, there may be some discomfort. Luckily, these mattresses offer good support and don't have many problems here.
Mattresses with high longevity are some of the most looked for by customers. But with companies focusing less on building quality products and more on shipping product, it can be difficult to find the right mattress that lasts. That being said, these mattresses specifically have high marks from customers on longevity. For most sleepers, they will last between 7 - 12 years. If you are larger in frame, you may find your mattress slightly less durable.

Customer reviews can be sometimes difficult to find and make sense of -- especially with companies coming in and out of the market quickly.

Research more below to learn about the specifics of the mattresses.
In terms of having lasting supportiveness, these mattresses have mixed signals from customers. Some customers feel like these mattresses provide a cozy comfort, but others had problems getting comfortable. If you have a heavier body type than average, you may want to do some added digging into reviews to make sure you find the right pick for you.
Edge support is an essential attribute for those that like to sit on the side of the mattress. Some customers have found these mattresses to not be evenly supportive.
Mattresses with lasting comfort are amazing, but not always easy to find. Unfortunately, these mattresses are not well rated when it comes to durability. That said, some customers may find their mattress lasts longer than average, while other customers may have much faster discomfort. If you are bigger in body type, take a look at the reviews before purchasing.
Just what I expected but I might need to exchange it. I bought the soft mattress. It feels like foam on a rather firm, supportive mattress. Sounds ideal for a side sleeper, but I'm waking up a bit sore in lower back. Honestly, it could be my medicine dose. I have to do a good trial with better pillows, regular dose of my medicine to be scientific. Arrived a day early. I managed to unpack it on my own. I'm a short woman with back pain and I didn't hurt myself unpacking it. It would be super easy for two people. I'm very happy i can exchange it if i need to.View More Reviews
The process to buy the mattress was so painless. It was so much better than stepping foot into a mattress store - I will never do that again. My husband threw his back out and we desperately needed this new one. So I called customer service and told them what happened. They were SO helpful and actually over-nighted the mattress to us so my husband could recuperate faster. I am very grateful. One thing to note - even though we have the "soft" version, it is much firmer than what I was expecting. It's not one of those foam mattresses than can be difficult to move around in. This definitely has a good amount of firmness to it. Even my husband, who loves a good, firm mattress, says this is great for him!
For the first time in months I wake up rested and NO back pain.
Still enjoying a great nights sleep on this mattress! Seamless process from selection to delivery to set up.
Delivery was timely, package was easy to open, mattress came to life immediately. Our mattress is firm and comfortable. We love it!
The morning after sleeping on it, I got out of bed and starting saying, "My back hurts." As soon as I said it though, I realized it wasn't hurting! I was just so used to complaining about my back hurting that I did it automatically without even thinking. It keeps me very warm a night!
I've only had my mattress for about 2 weeks now but so far I'm happy with it and am definitely sleeping better. It really is more firm than you would expect out of a "soft" mattress but it's actually what I prefer. I feel like I have more support that way. My best friend has a Leesa and my Cocoon is definitely a bit firmer than hers. I've bought foam toppers in the past and they never held up over time. I am hoping this foam mattress doesn't let me down. I have to say it is a really good deal compared to other bed in a box companies out there and the reputable company name sold it for me. Of course the great reviews helped too ;-) I plan on updated my review in the future to let you know how it holds up over time. Good luck, friends!
We love, love our new Cocoon mattress and foundation. I don't want to get out of bed! I'm now ordering them for our son's room and our guest room, too! Great customer service when I reached out with questions.
What an awesome mattress. The only thing I would suggest re: the cocoon would be to unpackage/wrap it on the floor completely before putting it on your bed frame. You have to take it off to get the last wrap off anyway.... Money well spent, very worth it, we will see how it holds up in the next few months before we come back to update our comments.
I just wish it is firmer. However, the piece is not firm enough for me so I have to return it.
This bed is very firm. From my personal opinion, I would give this bed a 7.5 out of 10 on a firmness scale. This bed causes me to wake up with back and neck pain, that I did not get from my older SPRING mattress. As for the "chill" cover, it does make the mattress feel a slight bit cooler to the touch, but after 15-20 minutes of laying in bed, you can kiss that coolness goodbye!
Thanks for the great bed.
The Chill Soft mattress was a great purchase, as it has given me a better nights sleep during the day, as I work nights. I have had problems with other mattresses, due to back aches from work, but the Chill Soft has helped ease my back pain. The Chill Soft does seem to sleep cooler than my old mattress, though not as much cooler as I wish it would be.
I bought 2 twin for my kids and they loved it! Firmness is just perfect. We currently have a Serta bed that we paid over 2k, some spots in the bed are now too soft and the edge support is really bad. Tried to claim for warranty but it seems like they're doing everything they can to not cover it. NO MORE SERTA FOR US!
The mattress is very comfortable and keeps my hot sleeping husband cool as advertised. It is on the firm side of firm but otherwise we are completely happy with our purchase. The delivery and set up were super easy, too.
I am a very sensitive sleeper, but once you lay on this bed you go off to wonderland! Usually, I get up several times during the night but with this bed, I'm dreaming and or sleeping until morning. The con is sometimes my ears or shoulders are little sore from being in such deep sleep but your body gets used to it and adjusts. Now I can't sleep on anything else. What am I going to do when I travel now?
Mattress arrived on time and was easy to open and set up. It is very comfortable both for me and my husband.
Wish I would of bought one sooner . Haven't slept this good in years!
So easy to purchase. So easy to unbox and unpack. So easy to place on a boxspring. So easy to sleep on from the first night. My Cocoon is the best bed purchase I've made.
Great mattress and I feel the wooden slat in the foundation.
First night was kind of rough but I think my body was adjusting to the new bed. After a few days of breaking it in I found that I'm more refreshed and limber with no more back pains. I would recommend this bed to anybody who's in the market looking for one.
I love everything about this bed super easy to put together and the mattress is so comfortable. I got the chill king mattress best decision, I couldn't be happier!
This is my third cocoon mattress. I initially purchased one for myself a year and half ago, I love it so much that I bought my mom a cocoon classic and a cocoon chill firm for a dear friend who was having back issues. They both love it and their aches and pains are gone. To top it all, unparalleled customer service.
I purchased this bed back in March 2017. It's now November. I love this bed now but I didn't love it when I first purchased it. I felt it was as too hard even though it was the soft version. However, my husband really liked it so instead of returning it, I bought a memory foam topper. That helped immensely. I now get amazing sleeps. I would definitely recommend this bed. The price was good as well as I had a coupon for $100 off.
The mattress cool at night. It is also very comfortable and great on my back.
Great support. Keeps me cool and comfortable. Best purchase I made last year. My only criticism is that the edges of the mattress are strangely too soft, softer than the rest of my firm mattress. It is too easy to slide off the edge when one sits to put on shoes. Otherwise, best mattress ever!
We recently got the cocoon soft mattress for our daughter. It is hands down the most comfortable mattress in the house and is great during story time.
Love how cool my mattress stays and its amazingly comfortable that i don't want to get up in the mornings.
Our new bed is so comfy! I have been happy with it since day 1. Ordering was so easy and so was set up. I will definitely buy another one for our guest bed.
I like the bed, but unfortunately it smells pretty bad hopefully the smell does away. I slept on it the first night and the next morning I felt dizzy. maybe it was the weather outside or something, but it could of been the flumes from the bed. I would suggest to anyone who buys this that they put it in a room after it has expanded and let it air out for a week. who knows maybe two weeks. I ordered a firm mattress, but maybe I should of ordered a intermediate. I don't get into it and say aww that is so comfortable.
It was so easy to get this delivered to my new apartment and I didn't have to wait for delivery men. The mattress is comfy and afforable.
It took a bit to get used to the difference in a foam mattress compared to a typical spring mattress. After the initial few nights of getting used it, I can't wait to crawl into bed at night!
We always purchase a firm mattress and this mattress is the firm we desire! The customer service agents are very helpful in answering any questions before purchase. It shipped quickly and was easy to set up. Thank you Cocoon for giving us a good night's sleep!
The way it's made and the ease of ordering and receiving it. The thickness is great, easy to get in and out for an elderly person.
I Love that I feel like I'm getting a full body hug while I sleep! Not too firm, not too soft, a perfect snuggle!! Love it!
I bought this mattress to put in my spare bedroom. Since purchase, I've had a few guests stay over and tell me how great the mattress is and that they were surprised I sprung for one of those -pedic mattresses that cost so much money! I tried the mattress out for myself one weekend, and decided to order a King for my bedroom. I usually toss and turn at night, but woke up in the same fetal position I laid down in the night before.
a comfortable mattress but soft feels too soft to my standard. Would be better if there is another choice between soft and firm!
The delivery process, unfolding and making the perfect bed to fall asleep in....I love this mattress and really pleased with the right amount of firmness for the "firm". Not too hard, and definitely not too soft--just RIGHT! Thank you Cocoon for making my nights better :)
Comfy. Sheets don't stay on well. Best sleep I have had in a while. Don't have to have my back popped back into place every day anymore.
Bought this bed after doing extensive research on different brands. The Cocoon bed came out a winner, far ahead of the others. My Cocoon bed was delivered promptly and set up a super easy. This is hands down the best bed I have ever slept on. I love this bed!
I have a MLily Bliss King Size Mattress and it's the BEST mattress I've ever slept on! For the first time in YEARS I am sleeping through the night and I don't wake up with aches and pains! It also doesn't make you hot! LOVE THAT! You can't pay enough money for how a great night sleep makes you feel in the morning! So thankful I have my MLily Bliss!View More Reviews
I bought this mattress its by far the most comfortable mattress I have ever owned. I previously owned a tempurpedic mattress and it use to always make me hot, I had had back problems for years until getting one, and within 2 days of sleeping on it, they went away. The cover on the mattress feels great, this was a fantastic deal and I'm thrilled.
Best mattress I have ever owned. Good support yet soft and comfortable. My wife and I are now spoiled as we cannot sleep on motel mattresses
It feels like luxury at first. I've owned a queen size for about a month now. I have woke up almost every night with severe sciatic and mid back pain. It's way to soft and offers no support.
I purchased this months 4 months ago. It has the cooling gel in it, but I wake up with night sweats and hot., I also started to develop an allergy to it, I sleep on my back, it causes me to itch like crazy, and doesn't stop. I had to buy a mattress topper 3'' thick to put on top of it to keep away from the memory foam, even with a mattress protector on it. Helped some, but now I am stuck with it. It is however very soft and comfortable. Pity about the heat and itching though. I upgraded to this from a Serta memory foam without cooling gel, and I should have kept it.
Without a doubt the WORST investment in a mattress I have ever made. One star is six too many.
Thank you Elliot & friend for personally coming to my house to drop off my mattress the next day after purchasing! Couldnt be happier! THANK YOU! - Christy W
This is the second Mlily mattress I have purchased in the last two years. I love my original one though you have to spin them around every other month or so because they really do form to your body...They also tend to be a little warm, I live in Ohio and rarely used more than a sheet all winter long, with my house set to 62 (62 is totally not low because my house keeps the heat in so it feels warmer for those of you that think I might possibly be a penguin). This mattress I bought for a friend of mine and it's just as comfy as mine. The off gas usually goes away within 24 hours and for some reason I tend to believe this mattress has less off gas than mine. So the sole reason for not giving it a 5 star is because I sleep hot and it isn't the coolest bed I've slept in, but it's uber comfy.
I bought one of these two years ago, paid about 750 for it and in my opinion, I got a heck of a deal. The bed is super comfortable and is comparable to other more expensive mattresses. I spin it about every six months or so and bc its a coil/foam hybrid, it's kept its shape nicely. Everyone who has slept a night in this bed says it's one of the better sleeps they've had. I recommend it.
So far so awesome. I'm a big guy with a serious accumulation of orthopedic issues. Used this to replace a twelve year old top of the line Sealy king size that was keeping both my wife and I up tossing and turning all night. Tried this in a showroom and I was so relaxed in five minutes I almost couldn't get up. It does sleep warmer than a conventional mattress, no doubt about it, BUT, it's a whole lot cooler than the old1st generation foams ( which I found intolerably hot). Super simple pakage shipping makes it a whole lot simpler to handle than a conventional, and we experienced very little if any issues with degassing odors or the foam reaching it's advertised thickness. Due to space issues our two new mattresses were unwrapped and left to reshape standing on their side, which may have actually helped, given the greater surface area exposure and reduced resistance that that orientation allowed. We've now had them (a pair of long twins) for several months and my 110 lb. wife found it too firm, so we replaced hers with something better suited to the princess and the pea and gave hers to our son, and he loves it. We'll see how well it holds up over time, but considering the difference in cost I could replace this every 3-4 years for what we spent on the last Sealy. We did also try probably two dozen similar offerings from the major names and the fanciest Sealy foam mattress was the only one we found that we liked as much or better, just not several thousand dollars better. I consider this proof that you don't have to sell a kidney to get decent night's sleep. Just hope it lasts. We also purchased a pair of the adjustable bed frames with the wired remotes (Pragma) and are equally impressed with them in terms of function and value. The wired remotes are actually a blessing in disguise for folks like me who are constantly losing one. The only caveat is that the twins tend to slide apart on their frames, so I'm working on addressing that (maybe Velcro or a retainer such as is used on the foot of the bed) but overall sleeping better than I have in years.
My wife and I have had this mattress for 3 years now, and it's still great. There is a little bit of a break in now, but it's still very comfortable and not too soft. It doesn't feel like a hammock as a spring mattress would, and it's actually still medium firm. I have back problems, namely lower back spasms, and this has helped me greatly. It works for back and side sleepers (myself) and stomach sleepers (my wife).
I actually bought this from a local vendor in my area. For years I have favored what my family lovingly calls an 'iron slab' for a mattress. I'm a firm supporter of a firm mattress. However, as I get older I got more aches and pains to go with my years and a hard as rock mattress is no longer ideal. But I didn't really want a cloud to sleep on. I cannot remember how I got turned on to memory foam mattresses, but after exhaustive research I surmised which one would be the best, this one wasn't even on my radar. Before buying the one I had selected online, I wanted to test out some memory foam mattresses in the store to make sure that it was possible for them to be comfortable and yet firm enough that I wasn't sinking into them. I went to 5 stores locally, 4 of the stores encouraged me to look at a Sealy, however, the vendor I had gotten my previous mattress from showed me the M Lily. I fell in love with the Lily, but I'm a cautious buyer, so I went home and did some research, and liked what I found. So I bought it two days later. I have had this mattress now for a week and I love it. I won't say that it wasn't an adjustment coming off of a spring mattress, because it was. This mattress is firm, I tried to punch it and it actually hurt my fist. However, the human body is heavy and this mattress will sink a little on the areas where you put the most pressure, namely your butt. LOL. And if you stay in one area for long and warm up I have noticed that the mattress foam seems to get almost 'gooey', however, move from that spot and everything goes back to the way it was. I love the quilted cover, I loved it so much I actually didn't put a fitted sheet on the mattress for the first 5 days. The top layer of foam is some sort of cool gel formula and you can feel it if you run your hand over the quilted top. Altogether, if you like a firm spring mattress than I would recommend this mattress for you.
Just bought one of these here in town. I've literally been in it all night and day it's awesome I weigh close to 300 lbs my wife doesn't feel me get in and out of bed it cushions my weight it's just a great mattress. Even our lil boston terrier loves it lol. Only thing I suggest is make sure buying online like this that you don't lose the 10 year warranty it's great for piece of mind
I bought my daughter this mattress a couple years ago. She loves is so much, I just bought another for my son. He is sleeping very well and loves it, too.
had back pain, headache and tired all the time, and all of it is fixed with this mattress. It offers great support while molding to your body and relieving pressure points. I weigh 240 lbs. Lets hope it lasts a long time
We just bought this mattress about a week ago and we absolutely love it! I was afraid of buying a mattress online so we went to our local furniture store where they had one of these for us to test out. Loved it, bought it, no regrets. It's not too soft not too firm. My husband doesn't like soft beds and I don't like firm beds but we both agree this is the best mattress ever. Also very afordable for what you get.
Bed will not last more than a couple years. Mattress will deform under your body weight until it is virtually impossible to stay on bed. Warranty is a scam. They will not honor the integrity of the mattress.
We were replacing a futon mattress on a day bed in our office/spare room. The futon was so hard it was like sleeping on a stone floor. The new mattress is perfect for me to sleep on when my partner has the flu etc. It has enough support but is similar to our memory foam mattress. When we unpacked it there was a slight smell as it aired but it was minimal and went away quickly. I'm quite happy with this mattress. It's perfect for my day bed. Other reviews have commented on how it bears up over time, obviously I can't speak to that concern.
7'' size is very comfortable: supportive yet soft. Makes my sleeper chair very accommodating, especially for older guests. Arrived quickly; packing odors dissipated within 24 hours.
Excellent product and great delivery service for a bulky product
We had purchased two 10'' Mlily mattresses for our vacation and everyone raves about them. So, when it was time to invest in a mattress for our main home, we thought we'd do the same. After reading dozens of reviews, we went with the 13'' Serenity pillow top model. The first night seemed like a dream. After the first night, my wife and I have experienced nagging lower back pain that can only be caused by the mattress. We are hoping that the mattress softens a bit with time, but so far we are less than completely happy.
Love it it's like sleeping on a cloud best purchase I've made so far
A great mattress, finally found the one!
Very impressed. Had reservations buying a cheaper brand as opposed to Tempurpedic, but the cost savings made it worth the gamble. We've had it for a month now. VERY glad we went this route. The bed is comfortable, sucking you in yet still firm. And the cost savings makes it even more worth it. I would recommend this bed.
It's high quality and makes spring mattresses seems like something dinosaurs would sleep on. If you can imagine being on a distant planet in anothe galaxy sleeping like a boss, this bed is what you'd be sleeping on. Seriously though, it's very supportive yet very comfortable. Stains easy but the lady who sold it to me said any foam mattress needs a waterproof cover. Why the cover isn't washable on this model is anyone's guess. Maybe the makers of the bed thought the buyers for these things were going to be single people that happen to be extremely careful about not having wine in bed...Also, yes, as the other review states, it is very comparable to the mattress at Ashley furniture and such. Maybe more comfy.
Heavenly. The most comfortable mattress I've ever had the privilege of lying on. I replaced my $3k Tempurpedic with the MLily and have slept much better.
I must admit I never would have imagined I would buy a mattress on the Internet without even trying it out first. Well we took a chance, and the whole experience has far surpassed my expectations. My husband and I were disappointed with our local store who carries Mlily. We went there and I liked the Bliss mattress and he thought it was too soft. So we tried out the Energize model and it was too firm for me. So while looking at the Mlily catalog they gave us, we both liked the tranquility mattress and thought that would be a good choice for us. Hybrid , middle of the road firmness, cooling feature and it was one of their higher end models as well as being featured on the cover of the Mlily catalog. Well our local store told us this Tranquility mattress was not available here and was mostly sold in Europe! Really??? Well I immediately looked it up online and found it on here for close to 500 dollars less than the bliss model at the store, with free shipping!!! Now...about the mattress...... It is absolutely wonderful!!! It arrived within 3 days of ordering it and came rolled up nicely in a blue tarp to protect it. We opened it and let it expand for 24 hours.... now keep in mind: I was sleeping on a 19 year old innerspring mattress and I was used to it being very soft, and having the roll to the middle and sink feature lol! Anyway at first I thought it was a bit firm for me, but I have been sleeping on this for almost 2 months and it has softened up just a little and I have been sleeping soundly throughout the night! Its firm but soft if that makes sense. I absolutely love this mattress and would highly recommend it!!! You have lots of support but when you lay down, it conforms to your body without sinking and it just feels dreamy!!! I feel more rested the next day and don't wake up 6 or 7 times throughout the night like I did on our old mattress. The seller we got it from was wonderful too! He went above and beyond to make sure some details were ironed out and helped with us choosing a new foundation for this mattress. We tried out several mattresses locally which were in the 3000 dollar range and this mattress feels just as good if not better than those. I highly recommend this mattress as my husband I have both recieved many positive ramifications as a result of purchasing this mattress:)
We stayed in a hotel suite that had this mattress. We loved it so much we bought one on amazon and it is exceeding our expectations. Love the gel that helps keep the bed feeling cool. The memory foam has great support and doesn't give you the 'sinking' feeling. It conforms to your body very nicely with comfortable support, it doesn't swallow you up. Overall we love this mattress, couldn't be happier.
We have had this mattress for two years. It started off great but not so good now. I wake up around 3:00 am now with my back hurting. The mattress top has gotten loose with the material pooching up. The support is just not there any more. Have slept on other beds (hotels, visiting family, etc) and I sleep well with no back pain. So now I have to put out another chunk of money for another mattress - not an easy thing to do with our income.
Never had any complaints for this bed. Very comfortable and at a great value. Do not pay over 800 for a queen size, otherwise you are getting majorly ripped off.
I have only had this bed for under 30 days but I am so sad I spent $2700 on it. I told the sales person I wanted a bed similar to my ICloud Tempurpedic. I was told this is better than the ICloud. Well, I feel like I am laying in a coffin. The bed sags so bad in the middle and to get out of it is like climbing Mount Everest. I do not have this kind of money to be spending on a mattress. Am so so sad I purchased this product. I would not even sell it to anyone but just take it to the dump.
