The Beautyrest Harmony Lux Diamond Medium Pillow Top is an outstanding mattress if you like something that has the initial body contouring comfort of a pillow top, but want a firm and solid overall mattress. With the highest amount of premium materials in it's class, this is arguably the best firm feeling pillow top available today.

Right Temp Wave Foam

RightTemp Wave Foam, new to the Harmony Lux collection, provides exceptional air channeling for better air flow, and uses carbon fiber to help regulate body temperature for cooler, more comfortable sleep.

MicroDiamond Memory Foam

Previously only available in the ultra premium line of Beautyrest Black mattresses, the Diamond now features MicroDiamond Memory Foam. This premium comfort material provides outstanding pressure relief to help reduce tossing and turning, and uses diamond particles that work as a conductor to help provide a cooler sleep environment. This feature works well with the carbon fiber found in the Right Temp Wave Foam.

New and Improved T2 Coil System

The T2 Coil System used in the Diamond is the best in it's class and provides extra support and durability to the lower back area by using two coils woven into one. This system is individually pocketed, which means it contours quite well, and is made from high carbon steel which is incredibly supportive and durable. Adjustable friendly, this coil system represents a big jump forward in mattress technology.

Seaqual sustainable fabric

All Beautyrest Harmony Lux mattresses feature Seaqual sustainable fabric. Seaqual recovers plastics from the worlds oceans and transforms them into high quality sustainable fabrics that feel great and promote cleaner oceans. Every queen size mattress has the equivalent of 50 reclaimed bottles, leading to a cleaner, healthier tomorrow.
