Cover	Featuring the same cover used in other GhostBed models, the cover contains a proprietary formulation developed in Japan where cooling properties are woven directly into the fibers of the yarn, creating the Ghost Ice Fabric. The Ghost Ice Fabric is instantly cool to the touch, and will absorb and trap heat that is released by the body. Molecular changes in the fabric will neutralize the heat, keeping the sleeping surface cool.	Our premium stretch-knit fabric cover with spun poly fibers that’s breathable and durable with a soft feel.

Comfort	3D Matrix Polymer Layer offers 3 dimensions of comfort:The 3D Matrix layer is an integrated thermal conductive gel polymer. As excess heat accumulates under and around the sleeper, it is absorbed into 3D Matrix layer. As a fully connected sheet, that absorbed heat travels away from the sleeper. Conventional Foam layers comfort you by compressing as different parts of the body "press" on the foam. The 3D Matrix layer is an omni directional layer which stretches in all directions to mold and contour to each individual part of the sleeper's body. The 3D Matrix layer is ergonomically designed which allows the sleeper to sleep on the mattress, NOT in it. The GhostBed 3D Matrix Mattress features the exciting new 3D Matrix technology. This new comfort layer technology is revolutionary because it automatically bio-adjusts to two different body shapes and body temperatures at the same time, creating the ideal sleeping environment for both sleepers. The 3D Matrix layer automatically bio-adjusts to both sleep partners through simultaneous heat diffusion and weight distribution - two critical elements in sound sleep. The 3D Matrix allows excess heat is drawn away from the body. The Gel Polymer layer stretches in all directions conforming to the body without causing it to sink into the mattress. Gel-infused Memory Foam absorbs and dissipates body heat as fresh air passes through the foam.	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	The core of the GhostBed 3D Matrix features the patented Ghost 3D Matrix innerspring coil unit with our Spirited Edge support Design. With two rows of specially reinforced coils along the edge of the bed make it easier to sit comfortably without slipping off the edge plus you can sleep right on the edge without feeling like you'll fall off. The 3D Matrix ensures body weight is distributed evenly, relieving pressure and reducing the body's need to reposition itself, allowing each sleeper to wake up well rested, free of aches and pains, and energized to embrace the coming day. Ghost 3D Matrix Soft Transition Foam is one inch of pure pressure relief. This layer contours to your body and reduces the need to toss and turn. Individually wrapped coils provide that sturdy, responsive support of traditional innerspring mattresses you're used to.	Choose our soft layer for a cozier, more "in-the-bed" feel. Choose our firm layer for a sturdier, "on-the-bed" feel. Engineered to be highly durable and resilient. We’ve tested it, and we know it bounces back every time.
