Cocoon Mattress Review (2024 Update)

Cocoon Mattress Review 2

The Cocoon by Sealy mattress was launched in 2016 and was one of the first all-foam mattresses to be sold online in a box. It was quickly met with success, and is now one of the most popular bed-in-a-box mattresses on the market.

The Cocoon by Sealy mattress is designed to provide pressure relief and support for all sleep positions. It features a top layer of cooling gel memory foam, a middle layer of supportive memory foam, and a bottom layer of high-density base foam.

The Cocoon by Sealy mattress is also backed by a 10-year warranty and a 100-night sleep trial. This means that customers can try out the mattress for 100 nights and return it for a full refund if they are not satisfied.

The Cocoon by Sealy mattress has been praised by critics and consumers alike for its comfort, support, and value. It is a great option for anyone looking for a high-quality mattress that is also affordable.

Here are some of the benefits of the Cocoon by Sealy mattress:

  • Pressure relief: The Cocoon by Sealy mattress conforms to your body’s natural curves to provide pressure relief where you need it most.
  • Support: The Cocoon by Sealy mattress provides support for all sleep positions, so you can wake up feeling refreshed and well-rested.
  • Cooling: The Cocoon by Sealy mattress features a cooling gel memory foam layer to help you stay cool and comfortable while you sleep.
  • Value: The Cocoon by Sealy mattress is a great value for the price. It is made with high-quality materials and construction, and it comes with a 10-year warranty.

I received a free Cocoon mattress for review from Tempur Sealy. The Cocoon mattress is a mattress in a box made by Sealy. Sealy has been in the mattress industry since 1881 when the founder, from Sealy Texas, began compressing cotton for use in mattresses. The company is now known as Tempur-Sealy making them the largest manufacturer of mattresses in the world.

The Cocoon mattress has been featured on Oprah’s Favorite Things list for 2016. Getting this endorsement from Oprah is a big accomplishment that should garner some recognition for the new brand.

Many of the newer online startups were created as a response to some of the offerings and business models that the traditional brands offered. I was eager to find out if Tempur Sealy would be able to compete with these brands through Cocoon.

Ordering the Cocoon Mattress

You can order a Cocoon mattress in two different levels of firmness through their website. You get free shipping with an estimate on when your mattress should arrive and it comes with a 100 night trial period. They even list 24/7 support which is something I have never seen before. The mattress arrives in a black box which gives it a sophisticated look and you can easily transport it to any room in your house to unbox. Below is a picture of the inside of the box upon opening. You get a fun picture in a frame:

Unboxing the Cocoon Mattress

Below is a video of me unboxing the Cocoon mattress. I noticed this mattress took a little bit longer to come to form than other boxed mattresses. I think this is in part because the top layer of foam is a bit denser than others.

Specifications of the Cocoon by Sealy

The Cocoon comes in 2 levels of firmness, a firm and a soft. According to their website, the cover is made of a stretch-knit fabric with spun poly fibers to make it breathable. They don’t list specific densities of their foams but the soft has 3 layers of foam while the firm has 2 layers.

My Cocoon by Sealy Findings 

I was able to compare both the soft and firm versions of this mattress. Which allowed me to do comparisons to help you decide which is best for you.

Here’s a picture illustrating sink in the soft version:

Cocoon Soft Sink

Here’s a picture of the firm version:

Cocoon Firm Sink

To get a sense of how they are constructed, I peeked under the cover of the mattress to show you how each layer reacts.

Here’s the soft Cocoon which has 3 layers:

Below is a video of the firm version which has two layers

As far as heat retention goes, I didn’t notice much difference between the two levels of firmness. Below is a video shot with my infrared camera to illustrate heat retention on the Cocoon Chill mattress:


Finally below are some videos of me dropping a bowling ball on the mattresses to illustrate motion transfer. Again, there’s really not much difference between the two as the top layer seems to be the same which is what is absorbing most of the motion.
Here’s the soft version:


My Cocoon Mattress Recommendation

What I like best about the Cocoon Chill mattress is the top layer. It is a very soft layer that conforms well and provides great pressure relief. Between the two, I liked the soft version the best. I really like to sink into my mattress and feel like it’s cradling every part of my body which this mattress does. It is cool to the touch and will help you unwind after a stressful day.

Tempur-Sealy is known for its high-quality memory foam mattresses and the Cocoon mattress is a very competitively priced mattress that incorporates top-notch materials with all the guarantees that a big brand like Tempurpur-Sealy can offer.

The Cocoon Hybrid Mattress

The Cocoon Hybrid mattress is a medium-firm mattress that combines the pressure relief of memory foam with the support and bounce of pocketed coils. It is a good option for sleepers of all types, but it is especially popular with combination sleepers and side sleepers.

The Cocoon Hybrid has a four-layer construction:

  • Cover: The cover is made of a soft, stretchy knit fabric that is designed to be breathable and cooling.
  • Comfort layer: The comfort layer consists of 1 inch of Perfect Fit memory foam and 2.25 inches of premium memory foam. This combination of foams provides pressure relief and contouring to the body.
  • Transition layer: The transition layer is made of 2 inches of high-density support foam. This layer helps to provide support and prevent the sleeper from sinking too deeply into the mattress.
  • Support core: The support core is made of 8 inches of individually wrapped pocketed coils. These coils provide support and bounce, and they also help to reduce motion transfer.

The Cocoon Hybrid mattress is available in a variety of sizes, including twin, twin XL, full, queen, king, and California king. It comes with a 100-night sleep trial and a 10-year warranty.

Overall, the Cocoon Hybrid mattress is a good option for sleepers who are looking for a medium-firm mattress that provides pressure relief, support, and bounce. It is also a good option for sleepers who are looking for a mattress that is breathable and cooling.

Here are some of the pros and cons of the Cocoon Hybrid mattress:


  • Medium-firm feel that is good for sleepers of all types
  • Provides pressure relief and contouring to the body
  • Good support and bounce
  • Breathable and cooling cover
  • 100-night sleep trial and 10-year warranty


  • Some sleepers may find the mattress to be too soft
  • The mattress may not be supportive enough for very heavy sleepers
  • The mattress is on the more expensive side

Is Cocoon Just As Good As Tempurpedic?

Both Cocoon and Tempurpedic mattresses are highly-rated memory foam mattresses, but they have some key differences that might make one a better fit for you than the other. Here’s a comparison to help you decide:

Comfort and Feel:

  • Cocoon: Cocoon mattresses are known for their softer, plusher feel with a good amount of sink-in. They’re a great choice for side sleepers and people who prefer a hugging sensation.
    Image of Cocoon mattress
  • Tempurpedic: Tempurpedic mattresses offer a wider range of firmness levels, from soft to firm. They’re known for their pressure-relieving properties and conforming closely to your body shape.
    Image of Tempurpedic mattress


  • Cocoon: Cocoon mattresses are generally more affordable than Tempurpedic mattresses.
  • Tempurpedic: Tempurpedic mattresses are known for their high quality and come with a steeper price tag.

Cooling Features:

  • Cocoon: The Cocoon Chill model has a phase change cover that helps to keep you cool at night.
  • Tempurpedic: Some Tempurpedic models also have cooling features, such as their Breeze line.

Warranty and Trial Period:

  • Cocoon: Cocoon mattresses come with a 10-year warranty and a 100-night trial period.
  • Tempurpedic: Tempurpedic mattresses come with a 10-year or 20-year warranty, depending on the model, and a 90-night trial period.


  • Cocoon: A good choice for budget-conscious sleepers who prefer a softer, plusher feel.
  • Tempurpedic: A good choice for people who want a wider range of firmness options and are willing to pay more for superior quality and pressure relief.

Ultimately, the best mattress for you is the one that feels most comfortable and supportive. It’s always a good idea to try out a few different mattresses before making a decision.

Here are some additional things to consider:

  • Your sleeping position: Side sleepers generally prefer softer mattresses, while back and stomach sleepers may do better with a firmer mattress.
  • Your weight: Heavier people may need a firmer mattress to provide adequate support.
  • Your budget: Mattresses can range in price from a few hundred dollars to several thousand dollars.

  1. I think I’ve got too many tabs open on my browser looking at Cocoon, Lull, Purple, Tuft and needle, Casper, Ghost etc etc etc……Naturally like with clothes and so many products they are all aimed at Thin, skinny, small people…..I guess I fall in that category, though at 180 I’m far above the 140-145 I stayed at for years. So any suggestions for heavier people? At least in my case, me being “normal” and her being heavier…….These mattresses are all designated for what the world views as “normal” people.

    • Hi Brian,

      At 180 the Cocoon will certainly work, no problem. I often recommend the Loom and Leaf for heavier people given it’s dense, firm foam. It is also a thicker than average mattress.

      • Hi,

        I am also overwhelmed with all the options, and need a mattress asap at my new place. The Sealy caught my eye because its the first I saw that specifies “firm,” which is what I’m after. So the Loom and Leaf is the firmest in your experience ? I’m somewhere between 220-240, been a while since I scaled myself. Your recommendation here will be greatly appreciated. I’m currently sleeping on a sleeping bag on hard tile. Thank You !

    • HI Brian – i am 5’9″ woman weighing 218 lbs. I bought the LEESA mattress (Queen) a year ago and I love it. it doesn’t sleep hot…you don’t sink into it – but almost float on the surface. it is extremely comfortable and I am so happy I bought it. I have it on wooden slats – which came with the bedframe I ordered from Amazon

      • does anyone have bed frame recommendations for a Leesa? I am looking for either a natural wood or white / beige upholstered / tapered look. seems if I find something the slats are too big, they’re out of stock or pricing is too high. thanks!

    • I think you should consider a thicker mattress. I suggest taking a look at some of the offerings from Brentwood Home

  2. Ok, I have to ask, what is considered “heavier people”. I wear a size 12 Petite, have curves, and am considered fairly normal sized by my communities description of “normal”. But, then again, a 43 year old woman that wears a size 5 and weighs 120 pounds in my neck of the woods would be considered for a trip to the ER to be evaluated for starvation. With that said, just what are you basing your normal sizing on? The comments above are kind of all over the place. In one answer, 180 will work fine; however, in the next one, a 6’5″, 230 lbs guy is too heavy. To me, the 6’5″ guy should be pretty thin, given his height. However, I could be looking at this completely wrong. By the way, is there a blog or website that has some sort of sizing chart for ordering these mattresses? Thanks so much!

    • This mattress will be just fine for you. In fact I’m 6’4 and about 200 lbs. and I sleep just fine on it. I use myself as a benchmark for heavy which is very subjective but I need to start somewhere. I worry that someone over 200 lbs. or so would bottom out when plopping down into the mattress. This isn’t a deal breaker for most since when you lay on it you won’t bottom out but it is an indicator of the limits of the mattress.

    • I’m 40, size 2 and 126lbs…so I need to be taken to the ER for starvation?! I don’t get why people think it’s ok to poke at being thin but your a jerk for making fat comments. I’m naturally thin, I don’t have to work at it, I have muscle tone too, and curves 🙂

  3. I have really bad back problems due to a accident. Which would you suggest to be the best suited? I’m 6’0 190.
    Thank you

    • It’s hard to say, I usually recommend a firmer mattress for people with back problems so I would try the Firm version first knowing you can always return it for free if it doesn’t work out.

    • It’s about a 7. Not terribly firm. What’s nice about it is the firmness comes from a very dense foam so even though it is, “firm” you still get good pressure relief.

  4. On a scale of one to 10, how firm is the “soft” mattress?
    I might order the mattress, but I’m worried the soft might be too soft with very little support.

    Any input would be great.


    • The soft is probably an 8 out of 10. If you’re at all concerned about being too soft, I would go with the firm. Because it’s foam, you will still get good pressure relief.

  5. Help me out here Ben! I’ve been reading majority of your bed in a box reviews for months now. What’s the hold up you may ask. I’m 5′ 110lbs with major back issues and he is 5’9 and I assume nearly 200lbs no aches and pains at all. Is there any way that either the firm or soft could be a good option for us both?

    • I think the firm would be your best bet. However if you both have drastically different firmness preferences, you may want to take a look at the Luxi.

  6. Please help us make this expensive decision!!! Mattress reviews are so overwhelming. I have fibro, and sleep like the princess in the story of the princess and the pea. However, the super soft and comfy memory foam we currently have (possible sleep innovations?) leaves my husband and I both with HORRIBLE lower back pain. How do we get the correct support for our backs AND sufficient softness for presssure points? He is 6’3″, 250. I’m 5’2″, 170 (if that’s relevant).

    • You should look for a mattress with a firm support base layer and then a soft top layer. The Cocoon firm would be a good choice but if you want something a bit softer but with good support consider the Amerisleep Revere.

    • Yes. I have used heated mattress pads on my memory foam beds. I recently used the Eight Sleep smart mattress pad which allows you to turn it on with your phone.

  7. I have had the Amerisleep Revere at the top of my list for quite a while , but price has kept us from purchasing. Would you say the Cocoon firm is a close comparison? I am 5’2″ and 130# and husband is 6′ and 200#. we both prefer a firm feel.

  8. I am looking for a firm mattress that has some softness (contouring) to it. I love the beauty rest hybrid luxury firm mattresses but they are insanely priced. I want a bed that I can sit on the edge and it not just sink like crazy (so good side support). I sleep on my side and back and my husband is a back or stomach sleeper. We are normal weights I think (160 and 210) but we have horrible problems rolling towards the center of the bed on our current (high priced) mattress. Can you recommend a good bed in the box for us? I tried sleep number with horrible results so I’m not inclined to have a bed with two different sides because I could always tell where the transition was to the other side of the mattress

  9. hello Ben I’m a 54 y/o female who is very heavy who suffers from joint issues, my husband is a 55 y/o male who is also over weight and we are looking for a mattress that relieve pressure point pain. I’m a side sleeper and my husband is an all over sleeper. We are strongly considering getting two full beds. I’m through with beds made with coils. Please Please help us. I’m 5’5 inches and I weigh 250lbs and my husband is s5’10 inches and he weighs 230lbs.

    • No, but you can buy a box spring online. However, it doesn’t need a box spring. You can put it directly on a slatted base. I really like the Zinus slatted bases because they are affordable and look nice. Here’s a link to their bed which is extremely affordable. You can also find there standard base on the Zinus site as well.

      The Zinus bases and frames were awarded a 2016 Good Design™ Award for innovative design and manufacturing by The Chicago Athenaeum: Museum of Architecture and Design.

  10. Would you recommend firm or soft for a stomach sleeper? My current mattress has some sagging in it that is causing some lower back problems for me. (6’1″ 170lbs) Thanks!

    • They are actually both very good with support. This mattress skews firmer but I usually recommend a firmer mattress for a stomach sleeper so in this case I would go with a firm.

  11. I owned a Brooklyn bedding mattress which was lost in a split. I really liked that mattress at 6’6″ 250-280 depending on the week. How does the sealy compare to the Brooklyn bedding ? I also hate sleeping hot and heat transfer even on the chill model doesn’t seem very good for hot sleepers. If this is all foam and no latex I think I need to keep shopping.

    Unfortunately I’m looking for s slightly more affordable mattress than the Brooklyn bedding which while inexpensive isn’t exactly disposable. I will likely need a mattress for a year before leaving the country so is this one going to work in firm for my size compared to Brooklyn bedding or is there another mattress which costs less than the bb and contains latex ? I see a lot of options from $250-400 on Amazon but I can’t imagine they’re any good.

    From the research it looks like $800 is about as low a price as I’m likely to get on something that works for my size.

  12. I have looked into the Cocoon, Bed in a box, and Dreambed. I’m not sure which one to choose. I am 5′ 120 lbs and hubby is 5’9″ 135 lbs. We both suffer from back and neck pain due to an accident. He’s usually sleeps on his back or stomach. However I am a side sleeper 90% of the night, what would you recommend? If it’s the cocoon would you recommend soft or firm? Thank you for your time.

  13. Two questions: do you know the difference is size btwn the king and California king? Also, do you need to use a certain type of sheets? Thanks.

    • A King is 76 in × 80 in while a California King is, 72 in × 84 in. With a Cal king you get a little more length which is great for tall people. However the drawback with Calforinia kings is that there are less choices for sheets and bed frames.

      You can use any sheets on this mattress. You can find all my sheet reviews here.

  14. Thanks for such a thorough review of the Cocon. Does this mattress offer any side support. I am a side sleeper that sleeps close to the edge of the bed.

    Thank you

    • It does have some side support but not as much as others. Since it is an all foam mattress it will sink in a bit. That said, because it is a denser foam, it will conform more to your body than other mattresses so it will keep you in your ideal sleep position which means a lot less tossing and turning.

  15. Is the chill functionality just a gimmick? I don’t want to waste two hundred dollars on snake oil
    Also I’m looking at the firm, as I like to sit up and read in bed. Is this a good choice?

    • The chill option definitely works. It is a phase change material they use in the mattress that draws heat away from your body.

  16. Sherpa100 coupon has expired. SLEEP is good for $100 off. Price is better than nectar, eluxury supply, Brentwood, for twin. You could change the rating for affordability upwards.

    We had already purchased an Alexander signature – it started to break down along the edges at 45 days. We switched for an Activex. Much better. Your readers need to know that Nest does not help you get rid of the unwanted bed if you “return” it. The buyer has to find a charity willing to take it, and take care of transporting to and getting a receipt from the charity in order to get refunded. So, buyer, be aware that this is not easy. Goodwill, Salvation Army, won’t take mattresses. Local shelters only want twin size and won’t take queen. Be aware of this before buying. Had I known this, I may well have chosen a different company. The mattresses are starting to be pretty similar, and like others I read your reviews and had 20 tabs open, going back and forth.

  17. Can you tell me if the nectar is comparable to either the soft or firm cocoon? Trying to make a decision between the two by tonight. We like firm but we are coming from an older coil pilliwtop and are concerned the firm cocoon will be too firm? Thinking the nectar may work?

  18. I am really on the fence for a new mattress, either cocoon, leesa, or tuft and needle. I usually will sleep on my side and sometimes wake up on my stomach. Any recommendations? I like the price of the cocoon as its the cheapest of all three but I want something that will not cause lower back and hip pain from side sleeping. I am a 24 M, 5’9, 165.

    • The soft version of the Cocoon still provides great support. I think you should give it a try. And you’re right that the price is very competitive for the quality of the materials used.

  19. Would you recommend putting two Cocoon Chill twin xl’s together to make a King? My wife prefers a soft mattress, whereas I am heavy at 270 and would probably do better with firm. I’m concerned with how the edge support would feel where they meet in the middle. Would it feel like a saggy matress in the middle? Do you have any thoughts on this issue?

    • Yes, many people do this and it works just fine. You will notice the transition in the middle of the bed but most couples sleep on their respective sides so shouldn’t be much of an issue.

  20. Hi Ben,
    First off I would personally like to Thank You for writing all of these detailed reviews and also for displaying the questions and answers to our questions. I can only begin to imagine how many questions you receive from people that you have answered just to see that same question (or something very similar) asked by someone at a later date. But instead of responding with something like “please read the prior responses to this” and asking people to go find it in a sea of Q& A’s, you take the time to respond to each individual which is rare especially with so many inquiries. For this reason I will be using your codes when I finally reach my decision on a mattress. I hope that it does help you in some way.

    Like many others, my quest for the right mattress has been an ongoing nightmare for the last 6 years since my 2nd spinal fusion surgery and I pray that it comes to an end here soon. Im sure you have had similar scenarios to what i am going to write here but I haven’t had enough time to read through every single page on theses mattresses so here is what I’m trying to find out….
    I am a 5’9, 140lb rather hot sleeper who has been sleeping on my back out of pain from most mattresses. On the rare occasions that I am in a bed that is comfortable (I travel for work…not the most convenient for my situation but I cope) enough for me to side sleep, I will. I’ve tried everything and I find that after about a week in a different bed is when the pain kicks in. So it sounds like the Cocoon Chill firm might be good for me with all things considered. I plan on reaching out to them to find out the details on the 100 day no questions asked return policy. But I also see in these Q& As here that a few other mattresses were mentioned as being good for these issues. I don’t want to get something for luxury/ aesthetics, but if you think there is something that’s better than the Cocoon Chill that I should consider I would like to know which one(s). While I don’t want to spend thousands, I also know how valuable getting good sleep is. Thanks again for reading!

    • Hi Beth,

      In your case, I think the soft version would be the way to go. Even though it is listed as soft, it has dense foam which gives excellent support. Given the construction of this mattress and the price, it’s a great deal.

  21. Hi Ben.
    I’m moving and cannot take my bed with me. It is a Sealy Posturpedic Belbrook firm mattress/boxspring from Costco. I love this bed, but they no longer sell it. Is it sold under another name? If not, what can you recommend? I was looking at the Cocoon simply because it looks easy to bring to a new apartment. Thank you for your help!

    • I’m not aware of a brand similar to that one. The Cocoon is a great mattress and if you go that route you would want to go with the firm version as it seems you are on a firm mattress now and like a firmer feel.

  22. We currently have a box spring and mattress set. Can you put the Cocoon mattress on top of a box spring?

    • Yes absolutley. As long as the box spring is firm. Usually box springs made in the past 12 years are newer box springs that don’t actually have springs in them.

  23. Hi Ben,
    I have been looking for a supportive mattress that has some softness just on the top so hugs my body a bit, I had a Simmons Beautyrest Recharge Grand Havan and it is getting softer over just 8 month of use, I just couldn’t sleep, pain everywhere. I am petite (5ft , 103lb) and I am trying to decide between Cocoon vs OSO, which seems to be very different in materials, what would you suggest? Thank you.

  24. Ben which is softer, the Nectar or soft Cocoon?
    I am down to these 2. I am a side sleeper, about 200 pounds. My wife is much lighter than me and is worried about it being to firm being foam. We are used to our old Simmons pillow top.
    Not sure which to go with.

  25. Debating between a Cocoon Chill (soft) and Nectar, both for price and comfort. I LOVE a soft mattress, and start the night on my side and end on my back. I’m 5’5″ and 130. Any thoughts?

  26. Looking for nothing too firm as I’ll be coming from a pillow top mattress. Looking st lull. Any others that you recommend?


  28. Our Sealy Cocoon is on the way, new fanel sheets washed and ready. Do I need to bu a mattress pad? The heated mattress pad sounds nice this time of year. Or should I wait to feel have the chill experience? We are transitioning out of a waterbed. Also like some many of my friends, I have night sweats due to change of life hormones or lack of…

  29. Thank you all for your advice and comments. I just finished sleeping on a purple mattress for 3 months. Feels lovely at first but I start tossing and turning after 4-5 hours. Unable to get comfortable with pain in my shoulders and hips (if on my side), in my back (if on my back), and in my knees if on my stomach. It has helped with sleeping hot but I need more support. I am 5’7” and weigh about 285. Help! I have tried innerspring, latex foam, air and now purple. Please help me find the right bed for me.

  30. I am looking for a comfy mattress that sleeps cool. I am torn between the Cocoon Chill and the Muse mattress. How would you compare the two?

    • The Muse is definitely cooler to the touch as they use more of the phase change material but it is more expensive too.

  31. I just bought the cocoon chill. Can you tell me a good mattress pad that will keep the chill feel to it? Or should I just put the fitted sheet on top without a mattress pad?


    • I would advise against a mattress pad as that will take away from the feel and cooling properties. Instead, invest in a mattress protector.

  32. I had a beatyrest pillow top mattress that was a mistake as it did not perform well past 6 months time and became too soft with a dip in the middle. I recently have purchased a cushion firm mattress, the Brysen from Scott Bros, Restora (something). This mattress is much too firm and created major pain for me in the shoulder, hip and legs. I will return it. I’m a side sleeper mostly and need a softer mattress., am 5’3” and 115 pounds. Will the Cocoon soft be a good choice to relieve the pressure point pain and provide a good comfy sleep? Or is there another foam or hybrid mattress that yo know will be better?
