No More Night Sweats: This original Chilipad bed cooling system is designed to make your existing mattress cooler. Its mattress topper fits over your existing mattress and plugs into a Cube that sits under or beside your bed. The Cube circulates chilled or heated water through the topper while you sleep. Use the remote control to change your bed temperature. Fits over any mattress. Includes 1 Chilipad and 2 Cube control units. Water-Based System: Use water to regulate the surface temperature of your existing mattress by actively circulating water through silicone micro-tubes in the pad, providing a more comfortable sleeping environment! Bedroom Setup: The pad connector can be placed at either end of your mattress to accommodate multiple bed frame styles, power source locations, and control unit access. Elastic straps allow the mattress pad to fit any mattress height. The Cube's sleek design easily fits under bed frames over 8 inches in height. Choose ME or half size pads for split adjustable beds. Wide Temperature Range: Temperature ranges from 60-115°F (15.5-46°C) so you can set it to your ideal bed temperature. Not meant to replace conventional A/C. Peak operating performance can be affected by ambient temperature and humidity. Easy to Install & Clean: Installs in minutes and Chilipad mattress topper is 100% machine washable and dryable. Settle into a warm, welcoming bed without cranking the thermostat.
