ChiliPad Cooling and Heating Mattress Pad - Fits single size mattresses. Your best night's sleep is a few degrees away! ChiliPad is a mattress pad with a cooling and heating temperature control system. It regulates the surface temperature of your mattress so that you sleep comfortably all night long. Designed to fit all standard and extra thick mattresses, this unique 150 thread count, poly cotton mattress pad uses soft medical grade silicone tubing to circulate regular water through the pad. A built in connection tube (48″ in length) connects the pad to the control unit. Dual-zone ChiliPads have separate tubing and independent control units for each side. Control the temperature at the touch of a button either directly on the control unit or conveniently in bed with the wireless remote control. Set the temperature in 1 degree increments from 46 degrees to 118 degrees F. The control unit heats or cools regular water to your set temperature and circulates it through the pad, generally achieving temperatures between 60 degrees to 110 degrees F on the bed surface. A thermostat maintains the set temperature, letting you sleep at your ideal temperature throughout the night. End battles over the thermostat and save money on your energy bill by cooling or heating your bed instead of your entire house! The control unit averages less than 80W of energy use, and dual-zone ChiliPads let you set each side of the bed independently. Fall asleep faster and achieve deeper, restorative sleep longer by controlling your sleep temperature!
