From soft cashmere to luxurious silks, the Lux Estate Gallium Firm Pillowtop Mattress provides you with the absolute finest in quality materials. The Primacool Performance Fabric is made with TENCEL, an ecofriendly fiber known for its moisture-wicking, breathable properties. The Advanced Adapt Foam is an exclusive formula foam that combines more adaptive comfort with better durability. Slower response provides indulgent comfort, while the faster recovery delivers better ease of movement. It also features Air vents to promote air flow for increased breathability and cooling. The Pillowtop Support Layer has individually encased IntelliCoil that provides contouring comfort and essential deep down support through the unique Steel-alloy, coil-in-coil design.
