ABSTRACT:
A footrest is provided comprising a base portion for placement on a supporting surface, a footplate connected to the base portion for receiving a foot of a user of the footrest, a heater connected to the base portion, an air intake system connected to the heater for drawing a first mass of air into the footrest, and an exhaust connected to the heater for expelling a second mass of air from the footrest. The heater receives the first mass of air, heats it, and expels it as a second mass of air. A warm air shield helps redirect the second mass of air expelled through the exhaust at the foot of the user placed on the footplate. The footplate may be made to pivot with respect to the base portion, or may be provided with a control knob so that a user may control the heater using her foot.
