The Mckee has a number of great features starting right with the silk, wool, and cashmere quilt that is very soft and also helps regulate the temperature of the sleeping surface. Comfort padding layers include PrimaSense Gel Foam, a pre-compressed polyurethane foam that offers consistent comfort and a long life expectancy, as well as Marvelux, an extremely dense comfort material. In addition, Advanced Adapt Foam is a top-of-the-line comfort material made by Tempur-Pedic scientists that is great at reducing pressure points and extending the comfort life of the mattress. A layer of PrimaCore Gel Foam reinforces the center third of the mattress and provides more support to the lower back where you need it most. Core support is provided by the Intellicoil Advanced system, a top-of-the-line Stearns & Foster innerspring design that provides a great combination of support and body contouring. These coils feature a dual-stage design that is made with tempered steel for long-term durability.
