Firmness info	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.	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.
