Bring home the latest in sleep technology with the Simmons ® ComforPedic Loft ™ mattress collection. Simmons ® ComforPedic Loft ™ mattresses are crafted with a thick, supportive layer of innovative NxG ® memory foam, which offers outstanding conformability and pressure relief. Its quicker recovery time eliminates the "quicksand" feel of some memory foam mattresses, and it dissipates heat, helping to maintain an ideal sleeping temperature through the night. Unlike some memory foam mattresses that take weeks to break in, ComforPedic Loft ™ mattresses conform to the body from first use. Each Simmons ® ComforPedic Loft ™ mattress is backed with a 20 year warranty.
