Simmons Comforpedic
Traditional memory foam mattresses are known for motion separation and pressure relief. Unfortunately, they are also known for sleeping hot and a sinking, hard-to-move feeling. That's why Simmons created NxG® memory foam, the better memory foam. NxG memory foam not only responds more quickly to body movements, but also dissipates heat to keep you at the ideal sleeping temperature. The result is a mattress that provides the ideal combination of comfort and support - without feeling like you are sleeping in quicksand. All NxG and Comforpedic mattresses utilize this 'next generation' technology.
