Firmness Info

Mattress Construction

Materials Overview

A 3-layer construction:

  • 3" 3lb Density CoolRest® Memory Foam Infused with Liquid Gel
  • 2" Pluralux Foam
  • 7" 2lb Density Sure Align Support Foam
  • Smooth Knit Cover.

The new 13" GhostBed 3D Matrix hybrid mattress has patented 3D Matrix Technology. This exclusive Gel Polymer layer scientifically adjusts to your individual body shape and temperature. The mattress is a seven layer construction:

  • Cooling Cover
  • 3D Matrix Polymer Layer
  • 1" Gel Memory Foam
  • 1" Ghost Bounce Layer (Special Gel-Infused Memory Foam)
  • 1" Ghost 3D Matrix Soft Transition Foam
  • 8.5" Individually Wrapped & Reinforced Support Coils
  • 1" High Density Support Foam.

Comfort Info

3 lb density memory foam rebounds (takes it shape) quicker making it easier to change positions.
The TENCEL® cover is a performance fabric like no other, absorbing moisture completely and naturally, creating a cooler and more comfortable sleep. With more breathability than cotton, and a softer hand than silk, TENCEL® can be found anywhere from athletic wear to luxurious bedding. Nothing is dreamier than going to sleep on a bed made with TENCEL® fibers.

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.

Support Info

Our CoolRest™ gel advanced memory foam quickly conforms to your body for pressure relief and support without letting you sink too far into the mattress.

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.

Comfort Specs

Open cell memory foam increases air flow, contributing to a cooler sleep.
Sure Align foam works in tandem with CoolRest® Gel memory foam and provides perfect support for long lasting comfort.

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 Specs

CoolRest® Gel memory foam perfectly contours to your body providing improved pressure relief to reduce tossing & turning.
Sure Align foam designed to support & correctly align your spine so you can sleep better.

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.

Fabric Specs

The TENCEL® cover offers unique moisture management properties - absorbs 50% more moisture than cotton, making it a highly effective performance fabric. Rapid absorption of moisture proves most effective in inhibiting bacterial growth naturally, without adding any chemicals.

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.
