Frequently Asked Questions

Do you offer removal of my old mattress?What is the difference between the Carbon and Diamond line?

The Harmony Lux Quilted line features advanced pressure-relieving foams, uniquely engineered cooling technologies, and exclusive sustainable fabric technology. While the Harmony Lux line is not our premiere line, like the Black is, this new line features some great options in a variety of firmnesses and feels! 


The Harmony Lux line is broken into two different categories, the Diamond and the Carbon. Both lines will have varying firmness options in both traditional top and pillow-top mattresses. The biggest difference between the Diamond line and the Carbon line is going to be in the materials used. 


The Diamond line is considered to be one step up from the Carbon line and has features built in to optimize for the coolest sleep experience possible while providing a great pressure relief system. 


The features you will find in the Diamond line that are not included in the Carbon line are Micro Diamond Memory Foam and Surface Touch Gel Memory Foam. The Micro Diamond Memory Foam is a highly conductive memory foam that moves heat away from the body, for a cool, comfortable sleep. The Surface Touch Gel Memory Foam is a premium memory foam located directly under the sleep surface; this particular design of foam unlocks immediate, advanced pressure relief.

What is the Seaqual Fabric Technology?

Seaqual is a community of individuals, organizations, and companies that are working together to help clean our oceans and raise awareness of the issue of marine litter by transforming ocean plastics into luxurious fabrics. 


Seaqual recovers plastics from the world’s oceans and transforms them into beautiful, high-quality sustainable fabrics that feel great and help promote cleaner oceans. Each queen-size mattress helps to eliminate the equivalent of up to 50 water bottles from our oceans.

What is the difference between the Quilted Harmony Lux Line and the Harmony Lux Hybrid Line? 

The Harmony Lux mattresses as a whole combine some of Beautyrest’s greatest innovations when it comes to support, comfort, cooling, and sustainability. 


The biggest differences between the Harmony Lux and the Harmony Lux Hybrid lines are in the design and make-up of the mattresses. The Hybrid line is a cross between an all-foam mattress and an innerspring mattress. 


When you lay on a Hybrid mattress, it will feel more comparable to a traditional foam mattress, with the added support of a coil base. Because the foams used in the Hybrid model are mostly memory foam, that material has a slower reaction time. As you lay on the mattress, it will take a few minutes to sink into the foam and receive the pressure-relieving benefits. The Hybrid models offer a great amount of support, but still provide the bounce you would come to expect from a traditional mattress. The Hybrid mattresses also have a flatter, more squared-off look. 


In the traditional Quilted Harmony Lux lines, the foam layers are a combination of polyurethane foam and memory foam layers. The top layers will be polyurethane foam followed by memory foam layers deeper down in the mattress. Memory foam is a slow recovery material, whereas, polyurethane foam is a quick response foam. This will provide a very different feel than a Hybrid product.
