Cleaning, Sheets, Miscellaneous
Can I clean the cover?
You can spot clean your mattress. The cover is not meant to be taken off or washed. If you are trying to remove a stain, dampen a cloth (do not saturate) with a mixture of water and delicate-friendly detergent. Gently scrub the spot and let air dry.
Does my mattress have a break-in period?
If you’re not happy with the feel of your new mattress, you have the option to exchange or return it. But we recommend sleeping on it for 30 nights—it can sometimes take a while to get used to a new mattress, especially if your old mattress was worn. But of course you can return it at any time during the first 100 nights.
What kind of sheets will fit my mattress?
You can use any sheet set designed to fit a 10” high mattress. For the bottom sheet, a fitted sheet with strong elastic fitted works best.
Can I use a mattress protector with my mattress?
Yes, you can.
Can I use a heating pad?
Yes, you can.
How much weight can it hold?
Your Cocoon™ by Sealy mattress can support up to 500 lbs.
Do you sell the bed furniture pictured on your site?
Sorry, no we don’t. Some of the photos and videos were taken in owner’s homes and some were shot on a professional set—but in either case, we don’t sell the furniture.
Building Your Mattress
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
- 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.
- The Premium Fabric Cover is both breathable and durable, with stretch-knit construction so you experience the “cushion” of the top layer.
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 your mattress use chemical fire retardants?
Cocoon™ by Sealy does not include chemical fire retardants, but uses an industry-standard “fire sock.” We put each mattress through grueling flame-resistance testing, and it passed. Rest assured that your mattress is held to the same standards that traditional mattresses are subject to—so you know it’s safe.
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.
Exchanges and Returns
Can I exchange my mattress for a different feel?
Yes, you can exchange your Cocoon™ by Sealy mattress one time during the 100 Night Trial, if you want to try a different feel. Call us (1-888-818-4039) and we’ll help you with the process of exchanging. After the one-time exchange, within the 100 Night Trial, if you’re still not happy, we will refund your money.
How do I return my mattress?
If you’re unhappy with your Cocoon™ by Sealy, call us. We’ll work with you to exchange or return your mattress. Depending on where you live, some of the options for “return” might include donating, recycling, or disposing of the mattress. In any case, once you confirm the return, we’ll issue a refund within 1 to 2 business days.
How long does it take to receive my refund?
Once we confirm the return, we’ll issue a refund within 1 to 2 business days.
Do I have to ship it back in its original box if I decide to return it?
No. We wouldn’t ask you to do that (it’s probably nearly impossible!). We’ll discuss how to get it ready when you call to talk about a return.
How long is the warranty on my mattress?
Your Cocoon™ by Sealy includes a 10 year full-replacement limited warranty.
Does the warranty cover defective mattresses?
Yes, it does.
What if the mattress starts showing dips and body impressions?
First, rest assured that it’s unlikely to happen—we’ve tested the foam extensively, and it’s proven that it can hold up for years of use. However, if it does happen, any indentations 1” or deeper are covered by the 10-Year Limited Warranty.
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, ARA and Fire-Retardant testing. But because we’ve been building mattresses for over 150 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.

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:
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
- Choose Soft if you like sleeping IN your bed; it feels cozy and more enveloping
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.
