We’re proud supporters of living your best life, and we know that can only happen when you’re getting the rejuvenating the sleep you deserve.

Watch How Its Made

The Chill Medium-Soft Mattress

Discover how each layer of the Chill Mattress adds up to a cooler night's rest. Perfect for those who like to be supported by their bed, but with a cushioned feel.

Select our Cocoon Medium-Soft mattress if you fall in the soft to medium range, and prefer a plusher feel (shown below).


  • Layer 1 of Sealy Essentials Compressed.png

    Our premium stretch-knit cover is infused with a proprietary “Phase Change Material” that absorbs and dissipates heat for a refreshing, cool to the touch surface.

  • Layer 2 of Sealy Essentials Compressed.png

    Our high-quality memory foam adapts to your body size, shape and sleep position to ensure you get a great night's sleep.

  • Layer 3 of Sealy Essentials Compressed

    Choose our Medium Soft layer for a cozier, more "in-the-bed" feel. Choose our Extra Firm layer for a sturdier, more "on-the-bed" feel.

  • Layer 4 of Sealy Essentials Compressed Mattress

    Engineered from heavier, more robust foam to be highly durable and resilient. We’ve tested it, and we know it bounces back every time.

Even the Setup is Chill

Your Cocoon™ by Sealy is shipped for free in an easily moveable box that measures 15” x 15” x 44”.

Unpack, unroll, and feel the difference for yourself.

What's The Difference?

Medium- Soft or Extra-Firm

We've found that most sleepers prefer a mattress that's fully supportive but not too firm, so we created a Medium-Soft mattress - which is our most popular and feels like you're "in the bed".

Some sleepers prefer our Extra Firm model for a more “on the bed” feeling.


  • 2019-04-23_9-34-05.original.jpg

    Perfect for those who like to be supported by their bed, but with a cushioned feel. Choose Medium-Soft if you prefer a plusher feel or are a side or multi-positional sleeper.

  • 2019-04-23_9-33-45.original.jpg

    Great for those who require sturdy support from their bed, with a robust feel. Choose Extra Firm if you prefer a denser feel or are a back sleeper.

Reviews Matter. We Have Great Ones!

I was skeptical about the "cooling" feature but I can definitely feel the difference in temperature. Convenience, comfort, and cooling...what more can you ask for?!
