Choosing and Ordering
How do I choose Soft or Firm?
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 supportive and more substantial.
- I’ve heard that one mattress fits everyone. Is that true?

Cocoon™ is only sold direct from us, and is currently not in retail stores. If you’re concerned about “trying it out,” read about our Unbeatable Return Policy.

Does my mattress have a break-in period?
We recommend that you wait 72 hours before your mattress has returned to its normal state following transit, during this period, any minor creases in the cover will recover. It can sometimes take a while to get used to your new mattress, especially if your old mattress was worn. But of course you can contact Customer Service for any advice on 0800 011 9555.
What kind of sheets will fit my mattress?
You can use any sheet set designed to fit a 25cm high mattress. For the bottom sheet, a fitted sheet with strong elastic fitted works best.

Yes, you can.

Building Your Mattress
What’s in my mattress?
Your Cocoon™ 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™ mattress, and Flexible Essential Support Foam for our Soft Cocoon™ mattress.
- Does it transfer movement from my sleep partner?
Does the new mattress smell?
When your Cocoon™ arrives, there could 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. We recommend that you air your bedroom during this period. Just as important to know: the smell is normal and short-lived.
Exchanges and Returns
How do I return my mattress?
If you’re unhappy with your Cocoon™, contact the Cocoon Customer Service. We’ll work with you to exchange or return your mattress. We work with partners such as the British Heart Foundation to minimise waste & issue your refund once we have received your mattress in a good condition, we can issue your refund.
How long does it take to receive my refund?

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 have partnered with the British Heart Foundation to help return your mattress. Customer Service will make arrangements for any return when you call them.
How long is the warranty on my mattress?
Your Cocoon™ includes a 10 Year Limited Warranty.
Does the warranty cover defective mattresses?
Yes, it does.
What if the mattress starts showing dips and body impressions?
