FAQs
Ghost SmartBed
How do I assemble the Ghost Smartbed 3d Matrix?
Setting up the Ghost SmartBed 3D Matrix® is straightforward. You'll receive two boxes: one with the pump and another with the mattress. First, unbox and unroll your mattress to allow it to expand.

Beautyrest Harmony Lux Carbon
How many coils does Harmony Lux have?
The Beautyrest Harmony Lux models all feature the same pocketed coil support unit, which includes 850 coils (in the queen size) and provides zoned support.
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.
