Experience superior comfort with the Millennium 2.0 Hybrid King Mattress from Sierra Sleep® by Ashley. This 16-inch mattress features a temperature-regulating Hyper Cool 4-way stretch knit cover designed to keep you cool throughout the night. Its construction includes high-density gel memory foam for lumbar support, body-contouring foam for balanced firmness, and a premium pressure-sensitive NanoCoil unit combined with individually wrapped coils to deliver restorative support and reduce motion transfer.
