Versatile memory foam mattress by Sealy

Cocoon highlights

  • While the Cocoon isn’t custom built for your needs, it still offers lots of options. You can choose between Firm and Soft (which differs in the central foam layer) or between Classic and Chill (which differs in the mattress cover).
  • Like other memory foam mattresses, the Cocoon performs well when it comes to isolating motion (the 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, you may want to shell out the extra $150 for the “Chill” mattress cover.

A look inside

The Cocoon is made up of three premium foam layers, one of which you can pick a soft or firmer option for.

  • Top – perfect fit memory foam adapts to your body and sleep position
  • Middle – personalized comfort layer
    • Choose soft for cozier, “in the bed” feel
    • Choose firm for sturdier, “on the bed” feel
  • Bottom – support foam designed to be durable and resilient
  • Cover – premium stretch-knit fabric cover that’s breathable and soft
    • If you go with the Chill version (an extra $150), 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.

What Cocoon customers have to say

  • “I love my new mattress. I can sleep much better at night and wake-up refreshed and most important of all- pain free. I used to have lower back pain and because of it I could not sleep on my back so I slept on either of my sides but by morning both of my sides would hurt so much that I could not lay on them anymore. Now I enjoy sleeping and waking up pain free. Thanks to Cocoon!” – Tanya (Firm)
  • “I had a Tempurpedic mattress which I loved. When it came time to get a new mattress, I decided to try the Cocoon with its much lower price. I was doubtful that, at that price, it would be able to compete. I’m happy to say I was wrong and I absolutely love this mattress. It’s extremely comfortable and I’d recommend it to anyone (and have!). The Chill seems to work very well, also. Even with more layers on than I used to have on my Tempurpedic, I don’t ever get overheated.” – Tiffany
  • “This mattress has been terrific! We replaced our 10-year-old Tempurpedic King memory foam mattress with two Twin XLs and a new adjustable frame and have loved it so far after about a month. We tried a couple of other mail order mattresses but they were too soft for our liking. The Chill Firm has been perfect. It feels just like our old, $3,400 mattress when it was new. Also, the edges on the Cocoon aren’t so soft you feel like you’re sliding off at the edges (which was an issue with the other mattresses we tried). There was about a day of off-gassing, but that was no problem at all; we just made sure to not cover it up with blankets/sheets until that was done. No regrets at all!” – Brian
