What’s The Difference?


We've found that most sleepers prefer a mattress that's fully supportive but not too firm, so we created a Medium-Soft mattress - which is our most popular and feels like you're "in the bed". Some sleepers prefer our Extra Firm model for a more “on the bed” feeling.

Cocoon Medium-Soft

Perfect for those who like to be supported by their bed, but with a cushioned feel. Choose Medium-Soft if you prefer a plusher feel or are a side or multi-positional sleeper.

Cocoon Extra Firm

Great for those who require sturdy support from their bed, with a robust feel. Choose Extra Firm if you prefer a denser feel or are a back sleeper.

Our mattress, pillows, and sheets all work together to deliver complete cooling comfort, from head to toe.
