Firmness Info
The Cocoon Chill is a medium firmness, about a 6 on the firmness scale. We've found that most sleepers prefer a mattress that's fully supportive but not too firm, so we created a mattress with our Perfect Fit memory foam that adapts to your unique body size, shape and sleep position.
The best way to feel the Casper Nova Hybrid is to take advantage of our 100-night, risk-free trial. If you're looking for a mattress that can sustain more weight, or you want to be lifted more than cradled, then our hybrids are a great choice.

Mattress Construction

Materials Overview
3 layer construction:
  • Perfect Fit Memory Foam
  • Personalized Comfort Layer
  • Support Foam.
Those who want a plush top layer without sacrificing support and cooling. Made with three layers of premium foam, plus foam-encased springs:
  • Breathable AirScape™ Polyurethane Foam
  • Zoned Polyurethane Foam
  • Contoured Memory Foam
  • Durable Base of Polyurethane Foam with Encased Springs.
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.
Cooling helps keep you at the right temperature for your best. Two layers of perforated breathable foam help reduce heat. Plus every mattress saves up to 70 recycled bottles from the environment.
Support Info
