Abstract
An electrically heated portable seat for automobiles includes a flexible and liquid-impervious container having spaced top and bottom surfaces, a sponge-like material bonded to the inner surface of the container, a liquid absorbed in the sponge-like material, and an electrical heating element for heating the liquid inside of the container. The seat is plugged into a wall outlet in a house just before its use. After the seat is warmed up, it is carried to a car and placed on the car seat.
