The ChiliPad is a mattress pad that uses the patented Chili Technology water circulation system to provide personalized climate control for your bed. Set the temperature using the control unit or by wireless remote while in bed. ChiliPad is available in single or dual zone. Dual-zone provides independent control for each side of the bed so sleepers can find their own preferred temperature. The control units use only 80W of energy on average. Save on utility costs by cooling or heating your bed at night instead of your entire house! Machine washable. Easy set up. Simple to maintain.
