Cover	A soft quilted, luxurious top layer of fabric greets you and provides a cool, comfy surface. This Thermic Phase Change Cooling fabric will help your body regulate its ideal sleeping temperature through the seasons.	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.
Machine-washable cover	No	No
Ergonomic handles	Yes	No
Comfort	A layer of cooling Titanium Infused Memory Foam, the most innovative foam on the market today. Gently unzip your mattress to reveal the patented TitanChill Endurance Foam®. This layer is is engineered to bring your body optimal support, with the freedom of the free exchange program during your 100-night trial to move to a different firmness. The top layer of convoluted foam provides an ergonomically supportive surface and a more airy, breathable surface than traditional flat memory foam. We use our SmartFlow air flow system with punched foams and breathable layers to achieve maximum air flow.	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.
Support	Combining the most innovative titanium infused foam on the planet and the support of high quality individual coils with extra edge support, The Alexander Hybrid Signature Series is the most comfortable mattress on the internet. The Alexander Signature Hybrid Mattress utilizes a very durable individually pocketed coil unit with edge support coils all around the perimeter. This provides a movement-free sleep surface and supports the back perfectly.	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.
