Firmness Info
Everyone has their ideal comfort level. That's why we've designed this comfort selector tool so that you know exactly what you're jumping into. Select from 3 firmness levels:
  • Soft, a 3/10 on the firmness scale, a light, gentle and flexible feel that conforms to your body.
  • Medium, a 5/10 on the firmness scale, the best of both worlds for an exceptionally comfy feel.
  • Firm, an 8/10 on the firmness scale, solid and stable support throughout your sleeping surface.
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.
