Cocoon Mattress Review Highlights

Top-rated cooling mattress

The Cocoon Chill by Sealy mattress is a memory foam mattress that is Sealy’s bed-in-a-box model. It is also one of our top picks for the best cooling mattresses for hot sleepers. Customers love the cooling responsiveness of Cocoon, and in this review, we’ll go into detail about pros and cons, sizes, prices, and how the Cocoon scored in our lab testing.

Read on to learn all about Cocoon.

What we love about the Cocoon:

  • While the Cocoon isn’t custom built for your needs, it still offers lots of options. You can choose between Extra Firm and Medium Soft (which differs in the central memory foam layer).
  • Like other all-foam mattresses, the Cocoon performs well when it comes to isolating motion (the medium soft model even more so).
  • If you tend to sleep hot, or are worried about the heat trapping that tends to come along with a memory foam mattress, the Chill mattress’s cover has phase change material that’s got you covered.

Cocoon Performance Highlights

✅ Pros

  • Sealy offers hassle-free, free returns during their trial period.
  • Motion Transfer: If you sleep with a partner, pet, or child, motion isolation is important. The Cocoon mattress had minimal motion transfer, meaning your partner won’t wake you by moving around.
  • Edge Support: People who sleep on the edge of the bed or use it to get ready need a mattress with good edge support. Memory foam mattresses usually don’t accomplish this, but the Chill mattress did with a 9 out of 10.
  • Spine Alignment: Side sleepers need a straight spine when sleeping as the middle of the body usually sinks too deeply into the mattress. The Cocoon Chill kept the body evenly supported and the spine aligned.
  • Responsiveness: Those who toss and turn at night should look for a bed that moves with them and isn’t racing to catch up. Combination sleepers will love to hear that Cocoon scored a 9 out of 10 in responsiveness.

❌ Cons

  • There will be a slight off-gassing odor when opening your new Cocoon mattress. The smell is normal and should dissipate completely within a week.
  • Sealy as a company doesn’t do much in the social impact world.
  • The Chill mattress only holds 500 pounds total weight, meaning this does not work for heavy sleepers.

How Firm is the Cocoon Mattress?

The Cocoon mattress comes in two firmness levels: medium soft, which is a 6/10 on the firmness scale, and extra firm, which falls at an 8/10. The medium soft option is great for all sleep positions, and the extra firm version works best for back and stomach sleepers.

What Sleeping Position Does the Cocoon Mattress Support?

Cocoon works for all types of sleepers. Side sleepers will have straight spines and the perfect firmness level to sink into the mattress. Stomach and back sleepers can choose the firm option for their alignment. Combination sleepers will get the most out of Cocoon’s responsiveness.

Does the Cocoon Mattress Sleep Hot?

The Cocoon Chill mattress specializes in cooling. This comes from its phase change mattress cover that absorbs heat and dissipates it, keeping you cool-to-the-touch and making it one of the best mattresses for hot sleepers.

Though the Chill mattress is cooling, it is still a memory foam mattress, meaning that a bed made with innersprings or latex foam will be cooler.

How Much Weight Does the Cocoon Mattress Support?

Cocoon holds up to 500 pounds of weight on a queen size mattress: not enough to support most plus-sized sleepers.

What Foundations of Bed Frames Can be Used with Cocoon?

The Cocoon will work best on a flat, sturdy surface, including an adjustable base, box springs, platform bases, and slatted platforms. If you choose a slatted platform, make sure the slats are no more than 5 inches apart and are at least 2 inches wide.

DreamCloud compatible bases

What is the Cocoon Mattress Made of?

The Cocoon is made up of three premium foam layers, one of which you can pick a medium or firmer option for. The Cocoon mattress is made in the USA and the foam used to make the Cocoon is CertiPUR-US certified, meaning it’s safe for both you and the environment.

  • Cover: Premium stretch-knit fabric cover that’s breathable and soft. The cover is infused with material that absorbs and dissipates heat for a cool to the touch surface. Be aware that this layer won’t be directly near your body if you decide to use a mattress protector, topper or thick sheets.
  • Top layer: Perfect fit memory foam adapts to your body and sleep position.
  • Middle layer: Personalized comfort layer made of polyfoam.
    • Choose soft for cozier, “in the bed” feel.
    • Choose firm for sturdier, “on the bed” feel.
  • Bottom support layer: Support foam designed to be durable and resilient.

  • “Have had this mattress for almost 6 months now. No more pressure points– just a comfortable night’s sleep.” -SD
  • “I was hesitant about purchasing a mattress in a box. But l’ve been very happy with the Sealy Cocoon mattress I purchased. I looked at Casper and the Purple Mattress and even the Sleep Number Brand. I decided to go with Sealy Cocoon based on Sealys’ reputation as one of the best and super consumer confidence In the brand. And I definitely made the right choice. I love it and got a great deal with a pair of pillows and a set of sheets as a bonus. Of course I am happy and having a great nights’ sleep was the goal. Mission accomplished!” -Dream
  • “I’ve been sleeping on this mattress for around 7 months now, and legitimately could not be happier. The mattress stays cool (which is really nice since I tend to be a hot sleeper). I also really enjoy how firm the mattress is. Often times I find that I wake up in the same position that I fell asleep in.” -CS
