Harmony Lux Diamond Series Medium

Starting at

Beautyrest’s new Harmony Lux collection brings the latest sleep innovations into perfect harmony with environmental responsibility.  The Harmony Lux Diamond Series Medium mattress finds the perfect balance between cooling, comfort and support to deliver a restful and rejuvenated sleep.

Top Layers of Comfort
Starting at the sleep surface, all Harmony Lux products include high-quality, sustainable fabrics made in partnership with SEAQUAL, the leader in ocean plastic recycling efforts.  By recycling and transforming ocean waste into a continuously woven yarn, each mattress from the Harmony Lux line helps eliminate approximately 50 water bottles from our oceans.  The mattress surface also features InfiniCool Lux Technology that is cool to the touch and works to deplete heat buildup for the sleeper.  Directly beneath the cover find comfort layers such as .75″ of SurfaceTouch Gel Memory Foam built into the quilt to provide a deeply contouring feel for the sleeper, as well as 1″ RightTemp Wave Foam, .5″ Firm Comfort Foam, 2″ Medium Comfort Foam and 1″ of Micro Diamond Memory Foam.  These layers combine together to provide cooling comfort and a luxuriously firm sleep surface.

Core Layers of Support
Harmony Lux utilizes a Precision Support System powered by T2 Pocketed Coil Technology. This support system promotes additional support in the center third of your mattress where the bulk of our body weight exists.  This added support enhances healthy back support while helping to distribute body weight evenly across the sleep surface.  The T2 Pocketed Coil features double to reduce motion and promote long lasting durability.

Our recommendation
We recommend the Harmony Lux Diamond Series Medium mattress for all varieties of customers including back, stomach or slide sleepers that enjoy a moderately firm sleep surface.  Customers dealing with heat issues will also find incredible relief and cooling comfort.
