Beautyrest® Harmony Lux™ Hybrid is the only premium Hybrid mattress to deliver a trio of sustainable technologies, proprietary ContourFit® Design construction, and our exclusive dual strand T2 Pocketed Coil® Technology. The Precision Support System™, with its unique dual strand coil design that’s made exclusively for Beautyrest is at the core. Directly above this are layers of premium foams, a high-density gel memory foam that contours to your body and a premium memory foam featuring actual diamond particles to help conduct heat away from the body. To top it off, a suite of cooling technology layers will help you fall asleep and stay comfortable all night long. Beautyrest has also expanded our partnership with Seaqual™ to offer their unique sustainable fabric technologies within each Beautyrest Harmony Lux™ Hybrid mattress. Seaqual™ is a leader in ocean plastic recovery and upcycling efforts.
