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.

Comfort
Siena means comfort. Comfort that helps you forget about the worries of the day. Comfort that tells your body, “relax, it’s time to recharge”. Comfort that helps you enjoy a long, deep, and soul nourishing sleep.
A top layer of memory foam helps reduce the amount of movement from your sleep partner. The Soft model reduces a bit more motion transfer than the Firm model. Phase Change Material (PCM) absorbs your body heat leaving you with a cool to the touch mattress experience.
Support
Some people love super soft mattresses. Some people love a rock hard one. Most people are somewhere in the middle. That’s why the Siena is a medium firm mattress, comfortable to sleep on, but also firm enough to correctly support your body.
Our high-quality memory foam adapts to your body size, shape and sleep position to ensure a great sleep no matter which feel is right for you. Support Foam base layer engineered to be highly durable and resilient. We've tested it, and we know it bounces back every time.
