The Celebrity Bed by Tempur-Pedic™ is 13.5" in height and features a pillow-top layer of Tempur® material on top of a slightly firmer Tempur® support layers. There are two air-flow layers in the middle to let air circulate through the mattress. The Tempur® material works to keep the spine aligned straight to prevent back pain. Often back pain results when a mattress fails to adjust to the body in a way that properly keeps the spine alligned. The Celebrity Bed is one of Tempur-Pedics most luxurious mattress available.
