All of the Harmony Lux™ Diamond Series mattresses feature Beautyrest’s latest innovations, working in harmony to deliver a better night’s sleep. A precision support system, powered by T2 Pocketed Coil™ Technology, an exclusive dual-strand coil design invented by Beautyrest, provides the support you need where you need it most—in the center third of the mattress. Multiple layers of soft, supportive memory and support foam, including SurfaceTouch™ gel memory foam, Dynamic Response™ and MicroDiamond™ memory foam, work together to deliver body-contouring comfort, superior pressure relief and support, while directing heat away from the body and promoting breathability. On top, the InfiniCool™ Lux sleep surface provides a cool, comfortable sleep environment, helping you fall asleep faster and stay asleep longer. All mattresses in the Harmony Lux™ series feature eco-friendly fabric, made from recovered ocean plastics in partnership with SEAQUAL,™ which not only maintains an ideal sleep temperature throughout the night, it helps to keep the world’s oceans and beaches clean by eliminating the equivalent of approximately 50 water bottles.
