  • 1. Unbox

    Slide the compressed mattress out of the box.

  • Built in North America

    We proudly design and assemble all of our mattresses in North America, using the same Sealy expertise that has been crafting exceptional-quality Sealy mattresses for years.

Choosing and Ordering

  • How do I choose Firm or Soft?

    Some people want to feel cuddled in their bed, while others love a wonderfully solid surface underneath them. Here’s how to choose between our two feels:

    • Choose Soft if you like sleeping IN your bed; it feels cozy and more enveloping
    • Choose Firm if you like sleeping ON your bed; it feels sturdy and more substantial
  • I’ve heard that one mattress fits everyone. Is that true?

    If there’s one thing we’ve learned in 130 years making mattresses, it’s that a mattress is a personal choice. That’s why we offer the two most popular options: Firm and Soft. Both offer durable support and conforming comfort – but in a feel choice that works for you.

Building Your Mattresss

  • What’s in my mattress?

    Your Cocoon™ by Sealy consists of two basic parts: a Comfort Layer on top and the Base Support System underneath that. Surrounding them both is our Premium Fabric Cover

    • The Premium Fabric Cover is both breathable and durable, with stretch-knit construction so you experience the “cushion” of the top layer.
    • The Comfort Layer uses our Perfect Fit Memory Foam, a high-quality, higher-density foam that cradles you.
    • The Base Support System uses our Essential Support Foam, a heavier, more robust foam that’s engineered to be highly durable and resilient. We use Reinforced Essential Support Foam for our Firm Cocoon™ by Sealy mattress, and Flexible Essential Support Foam for our Soft Cocoon™ by Sealy mattress.
  • Where is my mattress assembled?

    We’re happy to report that your Cocoon™ by Sealy is both designed and assembled in the U.S.

  • Does it transfer movement from my sleep partner?

    Cocoon™ by Sealy uses a layer of memory foam on top, and that helps reduce the amount of movement from your sleep partner. The Soft model reduces a bit more motion transfer than the Firm model

  • Does the new mattress smell?

    When your Cocoon™ by Sealy arrives, there may be a slight smell. Think of this like the smell in your new car. It’s the result of the cells in the foam opening. The most important thing to know is that the smell will disappear—typically during the first week. Just as important to know: the smell is normal and short-lived.



  • Has Cocoon™ by Sealy been product tested?

    Before we started to sell Cocoon™ by Sealy, we tested it using a full set of industry-standard tests, including VOC and ARA testing. But because we’ve been building mattresses for over 130 years, we add a few that go above and beyond the average to test foam and mattress durability. Rest assured: your mattress has passed a battery of extremely tough tests!

  • Are the foams in my mattress safe? Has Cocoon received any safety certifications? Is Cocoon certified by Certi-PUR?

    Yes, the foams used in your Cocoon by Sealy mattress are safe. They’ve been certified by the CertiPUR-US® program, a not-for-profit organization that conducts rigorous safety inspections prior to awarding certifications.
