A heated rubber mat comprising upper and lower rubber panels and an intervening carbon-loaded electrically resistive rubber heating element. All are vulcanized together to form a unitary mat structure characterized by good flexibility permitting rolling up the mat in any direction and by permanent shape retention, said heating element having spaced, flexible electrodes fully enclosed therein and bonded thereto, along with associated, thermostatically controlled current receiving means, whereby current may be transmitted through the portions of the heating element lying between said electrodes to generate heat and whereby the mat may be maintained at the desired temperature.
