For soothing warmth to cold feet and legs, this footrest delivers gentle radiant heat using less than 100 watts of power for energy-efficient operation. Its portable compact design means it can be used at home on the weekends as well as placed under a desk at work during the week. The versatile unit offers adjustable heat and three different positions in one easy-to-use design. Use it as an ergonomic footrest to help improve seating posture at work, or quickly convert it to a flat heated floor mat or to a vertical heated panel. Plus, it's safer than a space heater. There are no fans or blowers, no carbon monoxide risk, and it's never too hot to touch--which makes it safe around kids and pets. Other highlights include a safety switch that prevents overheating, a 6-foot AC power cord, and an elegant black-on-black embossed design that matches any decor. Made of molded hard plastic, the 90-watt ETL-listed heated footrest measures 12 by 18 by 5 inches and carries a one-year limited warranty.
