Beautyrest Harmony Luxe Mattress

Simmons Beautyrest Harmony Lux Medium Pillow Top

The Beautyrest Harmony Lux Diamond series is a premium mattress available for those who want the best. While similar to the Carbon series of mattresses the layer of Micro Diamond Memory Foam separates the Diamond series of mattresses from its predecessor by alleviating heat absorbed from the body into & away from the mattress, resulting in a cooler & more harmonious night’s sleep.

Beautyrest’s Precision Support System utilizes T2 Pocketed Coil technology to provide the kind of support that is especially important for those with medical complications requiring lumbar or back support due to the additional support in the lower-back areas, more specifically in the center third of the mattress.

Seaqual and Infinicool have both partnered together with Beautyrest to create an innovative new fabric technology that uses recycled plastic gathered from our oceans. This environmentally conscious but durable and luxurious new fabric provides and much cooler sleeping experience.

Beautyrest Gel Memory Foam and RightTemp Wave Foam sits on top of the pocketed coils to provide unrivaled pressure relief and cooling. RightTemp Wave Foam is engineered with conductive materials that are designed to pull excess heat away from the body.

Don’t settle for less and go with Beautyrest’s best.
