Mattress Construction

Materials Overview 3 layer construction:
  • Perfect Fit Memory Foam
  • Personalized Comfort Layer
  • Support Foam.
Comfort Info A top layer of memory foam helps reduce the amount of movement from your sleep partner. The Soft model reduces a bit more motion transfer than the Firm model.
Support Info Our high-quality memory foam adapts to your body size, shape and sleep position to ensure a great sleep no matter which feel is right for you.
Firmness Info Choose from two options - soft, our best selling feel, or firm. The Cocoon Soft is perfect for those who like to be supported by their bed, but with a cushioned feel. Choose Soft if you fall in the soft to medium range, and prefer a plusher feel. The Cocoon Firm is great for those who require sturdy support from their bed, with a robust feel. Choose Firm if you fall in the firm range, and prefer a denser feel.
Comfort Specs Phase Change Material (PCM) absorbs your body heat leaving you with a cool to the touch mattress experience.
Support Specs Support Foam base layer engineered to be highly durable and resilient. We've tested it, and we know it bounces back every time.
Fabric Specs 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.
