Sink into the plush pillow top and enjoy cool, luxurious sleep. The Beautyrest Harmony Lux™ Carbon Series mattresses feature a precision support system, powered by T2 Pocketed Coil™ Technology, an exclusive dual-strand coil design invented by Beautyrest, to provide additional support in the center third of the mattress, where you need it most. To help relieve the aches and pains caused by pressure points, layers of soft, supportive memory and support foam, including Beautyrest’s exclusive Dynamic Response™ foam, sit atop the pocket coils to give body-contouring comfort, relief and support, while promoting breathability and heat-control. The InfiniCool™ Lux sleep surface which covers the plush pillow top 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, which helps maintain an ideal sleep temperature throughout the night.
