Cocoon's Specifics

Quality of Materials

Using generations of expertise and learnings from building mattresses, Cocoon by Sealy offers two mattresses with a 10'' profile, the Classic and the Chill (for extra cooling) in a firm and a soft version. Both of these mattresses are priced competitively and have had good reception from reviewers. Here is what's inside:

Layer 1: In both mattresses, they have a woven cover made of a polyester blend -- the Chill version has phase change material to help dissipate heat.

Layer 2: In both versions they have 2'' of memory foam to provide contouring, which helps melt away pressure point pain.

Layer 3: This is where the difference between the firm and soft comes in. The soft has a 2'' of transitional foam that cradles the spine without aggravating pressure points for lighter sleepers, while the firm has 8'' of base material that provides lasting support of the back, shoulders, and hips.

Layer 4: While the firm version is done at this point, the soft version has an additional 6'' of base foam that supports the spine.

Overall Comfort

Most agree that this mattress has a very comfortable feel. A few that wanted a softer version complained about the 'soft' version being too firm for their liking.


Cocoon's two different firmness levels are on the firmer side for lighter sleepers so if you are looking for a very soft mattress, this isn't it. For average-sized side sleepers, the soft may be good for you, while the firm version is for stomach sleepers and heavier folks.

Back Pain Relief

The soft version of this mattress is a medium firm to light to medium build folks and should help with back pain. For those that are heavier, the firm should be a good option and provide proper spine alignment.


The Cocoon Chill's cover will provide a cooling surface for most sleepers. Some that are very warm sleepers may experience some heat retention after some time.

Who Is It Good For?

These mattresses are ideal for stomach sleepers and back sleepers -- those with lighter body types and are side sleepers may feel it is too firm.

Cushy support

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.

I No Longer Wake Up Every Couple of Hours!

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!

No more pain in the morning

For the first time in months I wake up rested and NO back pain.

Very comfy

Still enjoying a great nights sleep on this mattress! Seamless process from selection to delivery to set up.

Love our new cocoon!

Delivery was timely, package was easy to open, mattress came to life immediately. Our mattress is firm and comfortable. We love it!

Amazing bed

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'm diggin it

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!

Ordering them for every room

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.

Just what the doctor ordered!

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.

Nice design and easy to handle

I just wish it is firmer. However, the piece is not firm enough for me so I have to return it.

Best money I've ever wasted!

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!

Enjoying a good nights sleep

Thanks for the great bed.

A better nights sleep.

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!

Cool and FIRM

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.

Sleeping Beauty

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?

Easy and Comfortable

Mattress arrived on time and was easy to open and set up. It is very comfortable both for me and my husband.

Love it !!!!!!

Wish I would of bought one sooner . Haven't slept this good in years!

Love is sleeping on a Cocoon

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.

Not a 5 because..

Great mattress and I feel the wooden slat in the foundation.

Restful sleeping

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.

Great mattress!!

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!

No more pain

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.

It's a great bed

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.

Loved the Coolness

The mattress cool at night. It is also very comfortable and great on my back.

Almost perfect

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!

The most comfortable bed in the gouse

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.

A great night sleep, finally!

Love how cool my mattress stays and its amazingly comfortable that i don't want to get up in the mornings.

Love it!

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.

nice but it smells

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.

Super comfy and super affordable

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.

So comfy!

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!

Finally a good night's sleep!

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!

Soooo comfortable!!!!!!!

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.

Most comfortable nights sleep EVER!!!!

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!

"Best Guest Mattress" - every guest

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!

Over the moon happy w/ my Cocoon!

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 :)

Finally a great night's rest!

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!

Resting Easy

This mattress is nice & firm...I rest well! I recommend it.

Not sure how "chill" the Chill mattress is...

First, I do enjoy my bed but I am not sure how life changing it has been for my sleeping. Second, I would recommend to others because everyone is totally different and this bed could be perfect for someone else. However, the chill part still perplexes me because I live in AZ which is why I purchased the chill version but it might be a myth. I certainly do not feel more "chill" when sleeping is all I mean.

Lifetime Insomniac

I have issues my whole life with insomnia. I also suffer fom extreme stress due to tragic loss of several loved ones This bed has helped change my life. I get in it and just melt. The days go away and I drift off easily. Im not even having to take my sleeping meds anymore. Thank you, Cocoon!

So far so good

So it's only a week and I think it takes a bit longer to know for sure but it seems good so far!

Great Support!

I was a little leery of ordering a mattress online without first being able to test it out, but from the first nights sleep our fears disappeared. Very supportive without being hard as a rock. I cannot wait to get into bed every night.

Mattress Amazing

This was by far the easiest way to buy a mattress and is the best sleep I have had in years.

Most Comfortable Bed I Have Ever Used

This mattress is amazing. I have had it for three months or so, and every night I lie down in it is like the first. I sink down into it just the right amount, and the comfort is incredible. Shipping was quick, and I have no complaints there. The frame, which I would also recommend, is very nice. It's a lot lower to the ground than I realized when I ordered it, and it makes a few squeaks every once in a while. Overall, it's totally worth buying to complement the mattress. TL;DR: Approve, get the foundation, if you're going to buy the mattress.

nice looking!

Love the ease of receiving it, unpacking it was fun! It has a very nice look, I ordered the soft one, but it was still too firm, I now have 2 foam style pads on it and this has helped.

happy husband happy life!

got the chill firm to keep us cool at night and help with the softer mattresses we were encountering. got the box, opened it up and its been a great nights sleep ever since! a friend also has a cocoon and loves it. now we can see why!!!!! don't hesitate to purchase this mattress--its all reward and no risk! sleep well my friends!!!!!!!! #CUCKOOFORCOCOON


We were totally shocked how comfortable our new bed is. I have Fibromyalgia and a host of Chronic Pain issues and I'm able to lay in bed with additional pain. Who would've thought a foam bed would help someone with extreme pain!!

Love it!

I love my new Cocoon matress!

so nice

like sleeping on a cloud is an understatement

Awesome mattress!

I'm getting the best sleep I've had in years! The compact way it was delivered was perfect. I was able to get it up to my third floor walk-up all by myself. Easy peasy. Hooray for better sleep!!!

Amazing mattress!

Love everything about this mattress!


Bought two new mattresses for the kids. Easy delivery and setup. They love the new beds and we couldn't be happier with how they are holding up. It's been a few months and they are still loving how comfortable they are.

Comfy bed, terrible customer service

The bed has been comfortable so far. I am very happy with it. However, I asked Sealy for a specific delivery date, which they said was out of their hands and that I should contact the delivery company when I get the shipping notification. I was never notified when it shipped and my order status never changed, and it delivered when I was out of town and sat outside for 3 days. I'm glad it wasn't stolen!

Very comfortable sleep for both of us

We sleep more soundly now as we don't feel as much movement when one of us turns over, etc. There was some "new" odor to the mattress for the first week or so, but only noticeable when my head was directly on the mattress vs. my pillow. It's a heavy package (85 lbs) and the unpacking instructions weren't really accurate because there is a plastic sealed envelope on the mattress that must be removed AFTER the initial outer wrapping is removed. This required slicing open the plastic and slipping the packaging out from under the mattress. It's still new, but for now I really like the mattress and how easy it was to get it here.

Great mattress

I love this bed. No box spring to deal with, easy to rotate and unpacking was simple. I have had mine for 10 months now and have seen very little break down. Well worth the money...will buy again in future.

Fantastic Mattress!!

My husband and I had been sleeping on a rather aged mattress for over 10 years. each morning one of us would wake with some various ache or pain. After seeing a commercial on tv for the Cocoon by Sealy we decided to give it a try, and I can honestly say that it was the best decision ever. I for one feel like I'm sleeping on a cloud and have not had a bad night or an achy morning since the mattress arrived, my husband says too that it is the most comfortable bed that he has slept on. We can't recommend it highly enough!

Best mattress I have ever had!!!

I have a bad back and this mattress is the best thing ever! My back doesn't hurt when I wake up in the morning!!!

Best mattress

Great mattress great price point

Incredible comfort

I was skeptical about ordering a mattress online, but after reading reviews and the 100 night guarantee, there really wasn't any risk. Due to a back injury, I had been sleeping on a yoga mat on the floor for several weeks, so when the Cocoon arrived, I was in Heaven. It's been four months and I still look forward to crawling between the sheets each night. The best purchase I've ever made.

Toddler bed, great for parents too!

We went back and forth when moving our child from co-sleeping to sleeping on their own. Our mattress is a foam mattress so when we tried to lay him down in a crib, with the typical crib mattress he was having none of it! He would cry and cry, so we decided to go with a foam mattress on the floor, montessori style. My husband did a lot of research and we visited a few mattress stores (which was a new experience for both of us). Mattresses are expensive! Who knew? He told me about the cocoon and we compared the different in store mattresses to the specs for the cocoon. We wanted something like ours, but the cooling option was great since our house does not have AC. When transitioning him to sleep on his own, I spent a lot of nights sleeping in his room and the floor is hard, so I decided I was going to move him over and do some bed sharing. While it states soft, this mattress has a lot of support, and for a twin both a squirmy toddler and a pregnant mom fit no problem. The cooling feature is great, and since it is foam I have no qualms with leaving it on the floor. We will be purchasing another for our next son in the near future! Love this and recommend it to any Moms who ask. We were never worried about the foam and suffocation issues even though it states soft, it is not a sinking soft, it is a comfortable soft that still holds you up. If you are on the fence try it out, you will not be disappointed

Good mattress but not worth the price!

I liked that the mattress was soft and fairly comfortable, but it didn't seem worth the price to me personally. Maybe that's because I'm young and not rich and frugal with my money, but ultimately, it didn't turn out to be an investment that I'm comfortable with at this moment.

Good mattress

We did a lot of research and tried another brand before buying a Cocoon - the other mattress was so uncomfortable I couldn't sleep on it. There is a bit of a break-in period, and we had to put a mattress topper on it because it was too firm. We've had it for 7 months now and it still seems about as firm as when we originally bought it. I wouldn't say it's changed my life, but overall, I like the mattress. It works well with the adjustable bases we purchased.

Solid mattress

Very comfortable and good quality mattress for a good price

Wish I had bought it sooner !

I bought the chill firm mattress in June. Before getting my cocoon mattress I was suffering back and hip pain to the point that I was waking up during the night. It took a few nights to get used to the firmness and the chill feeling but I love it ! I have recommended this mattress to everyone I talk to that mention they need a new mattress ! I wish I had not waited so long before I ordered. This is a great product , well worth the money and the ordering experience went smoothly . I don't have any complaints.
