Selectable Firmness
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. Softer top of the bed to give you that plush comfort you love. Like sinking into a cloud. A 2-3 on the firmness scale. 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. If you already know that you love a soft or firm mattress then follow your heart. However, if you are unsure you can follow this quick guide to make a selection:
1. Back Sleepers and Stomach Sleepers should choose the Firm Mattress
2. Side Sleepers and 'Free Style' Sleepers should choose the Soft Mattress
3. If either you or your partner is heavier than 220 lbs, the Firm Mattress may be the option for you.
4. If you are lighter than 130 lbs, the Soft Mattress may be the option for you.
