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 Zoma Sports Mattress is most comfortable for back and side sleepers, as stomach sleepers may find it too soft. Zoma's Triangulex technology makes back and side sleeping more comfortable, too, as it offers extra support for your torso and adequate cushioning for your shoulders to prevent tossing and turning and keep you sleeping soundly all night long.

Comfort	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.	Zoma mattress materials are made with Variable Pressure Foaming, a process that produces naturally open-cell foams. This helps reduce the buildup of uncomfortable heat and moisture. The Reactiv layer of is designed with enough bounce and responsiveness to keep you lifted in the mattress instead of sinking uncomfortably far into the bed. Plus, this layer isolates motion, so you can toss and turn as much as you want without disturbing a sleeping partner.
Support	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.	The Zoma is a memory foam mattress designed to help athletes sleep deeper and recover faster, but even if you aren't an athlete, you can benefit from Zomas sleep-promoting technologies. Equipped with contouring memory foam for cushioning comfort and responsive support foam to prevent sinkage, the Zoma has everything you need to help you get the sleep you need to perform your best day-to-day. The Zoma Triangulex layer includes 3 zones (Head & Shoulders, Hips & Lower Back and Upper & Lower Legs zones) that help to reduce acute pressure on the mid-body and lead to overall better spinal alignment during side-sleeping. The Triangulex is made up of hundreds of triangular segments spaced according to the strategic comfort zones. Reactiv responsively contours to the body to minimize motion transfer and provide continuous support. The result? An undisturbed rest and active recovery. Support+ is the high-density base for the Zoma mattress. It provides consistent, reliable pressure relief for the hips and shoulders, while maintaining the spine's natural alignment.
