STURDY, STRONG, AND SAG-FREE: engineered with high-quality materials to support 1,000 lbs while providing maximum comfort while you sleep. CONTOURING COMFORT: 13 inches of layers built to support the big, tall, and powerfully strong while offering the most plush design available with a medium firm feel at a 6/10 on firmness scale. PERSONALIZED SLEEP: Mattress developed for two styles of sleepers: plus-size sleepers who want ample support, but require a more medium-level feel and plus-size sleepers whose partners are not necessarily plus-size and require more contouring. COOLING: The GlacioTex+ Cooling Cloud Pillow Top is designed to wick away heat and keep you at the ideal temperature while the hybrid design and porous foams promote optimal breathability.
