The Firmest Hybrid In The Line

by Jed Harrington

The Beautyrest Black Hybrid X Class Firm is an exceptional hybrid mattress that boasts some of the most advanced support and comfort technology being used today. If you like a firmer feel and want one of the best mattresses available, this is a great way to go.

Firm, Yet Contouring

The X Class Firm feels very firm overall, but has enough high end comfort materials to properly contour to the lower back and feel quite comfortable.

Top of The Line Support

The T3 Pocketed Coil System is one of the best in the industry. The 3 piece design is strong, contouring, and supportive. It's ability to reduce motion transfer means less disturbance when movement occurs, and it's fully compatible with all adjustable bases.

Black Ice Hybrid Technology

Beautyrest's most advanced cooling technology, Black Ice Hybrid Technology feels incredibly cool to help you fall asleep faster and sleep cooler.

Self Response Latex

Self Response Latex is one of the best materials used today. It's designed to provide outstanding pressure relief, but also pushes back against the body for added support. It's anti-dustmite and anti-microbial for a cleaner sleep environment.

CertiPUR-US Certified

All Beautyrest Black Hybrid mattresses feature foams independently tested and certified by CertiPUR-US to ensure they meet or exceed the highest quality standards.

A Fantastic Top Of The Line Firm Mattress

From the quilt to the coil system, the Beautyrest Black Hybrid X Class Firm mattress is builtto be the epitome of luxury. Does it succeed? Yeah, it does. If you like a firm mattress and want something that sleeps cool, feels supportive, and helps promote a clean sleep environment, this is the way to go.
