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 base model (CF1000) is a medium comfort. Choose the cooling upgrade (CF2000) model if you prefer a firm feel. Both the Max Cooling Upgrade (CF3000) and Max Cooling & Pressure Relief Upgrades (CF4000) offer a selection of feels - medium, plush, ultra plush and firm, plush, ultra plush.
