The ChiliPad™ Cube is a mattress pad with a cooling and heating temperature control system. It regulates the surface temperature of your mattress by actively circulating water through a network of micro tubes. The mattress pad comes in Single and Dual Zone. The Single Zone has one Cube and cools or warms the bedding surface for one person. The Dual Zone Cube has Dual Temperature Zones on larger beds with 2 Cubes, so the two sides can have different sleep temperatures. The result is the perfect temperature to doze off and get the rest you need to tackle the rest of your day.
