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.

Emma

Is the Emma Sleep mattress a good investment?

The Emma Sleep mattress is an excellent choice, particularly for those who sleep on their backs. Despite being an all-foam mattress, it offers a perfect blend of comfort and support that back sleepers require. It also provides adequate support for stomach sleepers, which is quite an achievement for an all-foam mattress.

What makes the Emma Mattress unique?

The Emma Original is made with Visco Memory foam, which perfectly conforms to your body shape, providing relief to sensitive pressure points and ensuring spinal alignment. The mattress also has a high-resilience extra foam layer at the bottom that offers additional back support as you sleep.

Why does the Emma mattress feel warm?

The warmth you experience with the Emma mattress is due to its construction from synthetic foam, including memory foam. These materials are known for their heat retention properties. Vasco elastic foams like memory foam respond to, retain, and build up heat to function effectively.
