The TEMPUR-Ergo� Power Base is essential to a holistic sleep experience. Features such as QuietMode� a setting which gently tilts your mattress to an anti-snore position, or the Zero Gravity preset which closely simulates weightlessness and helps take pressure off your back by perfectly elevating your head and feet, and even easy to reach USB ports found on the side of the power base are all parts of the TEMPUR-Ergo� Power Base system designed to offer you a premium and relaxing experience. Not limited for sleeping, with a head tilt range of 57� and foot raise range of 46� you can choose nearly any position for reading a book or watching a movie. Paired with a wireless, easy to use remote the TEMPUR-Ergo� Power Base is the perfect addition to your Tempur-Pedic sleep system.
