FAQs
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.
Sleep EZ Organic Latex
Do we carry any blended or man-made latex?
No, all of the latex we carry is made from 100% natural rubber from a rubber tree. The final product is 98% pure rubber, with the remaining 2% consisting of natural fatty acids, natural soaps, and natural reinforcing agents needed for manufacturing.
Can I wash the cover?
The cover is removable but not washable. It is recommended to spot-clean the cover with a mild detergent and a brush, then place the cover in the sun for disinfection. The cover cannot be machine washed, dry-cleaned, or hand-cleaned in the bathtub as it will shrink.
What type of fire barrier is in the mattress?
No chemical flame retardants are added or used in the mattress. The cotton and wool cover contains 1" of wool that acts as the natural fire barrier. This wool is also excellent at temperature regulation and wicking away moisture.
