| Cover | Seaqual Fabric Technology utilizes recovered plastics from the ocean to create a durable and luxurious fabric. | 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. |

| Comfort | Featuring our RightTemp Wave Foam, our Harmony Lux Carbon Series sleeps cool and comfortable all night. Consistently cool and comfortable. InfiniCool Lux is a system of layers in the cover and right below the cover that are cool-to-the-touch. | 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 | Beautyrest® Harmony Lux Carbon Series features our latest innovations in support, comfort, and cooling that work together in harmony for a better night's sleep.

BeautyEdge® for reliable edge support. Our Precision Support System powered by T2 Pocketed Coil Technology provides additional support where you need it most. Beautyrest® Gel Memory Foam and RightTemp Wave Foam work together to create incredible pressure relief. | 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. |

How many coils does Harmony Lux have?

What is the Seaqual Fabric Technology?
Seaqual is a collaborative initiative aimed at cleaning our oceans and raising awareness about marine litter. They convert ocean plastics into luxurious, high-quality sustainable fabrics. These fabrics not only feel great but also contribute to cleaner oceans. Each queen-size mattress made using Seaqual fabric helps to eliminate the equivalent of up to 50 water bottles from the ocean.
How do I know which firmness to select when I am mattress shopping?
The choice of mattress firmness is subjective and depends on your personal preferences and problem areas. Stomach sleepers generally benefit from a firmer mattress, while back sleepers find comfort in a firm to medium feel. Side sleepers often prefer a medium or plush mattress with extra pressure relief. These guidelines can assist in narrowing down options, but personalized recommendations based on individual needs can be obtained from the Customer Support team.
