ABSTRACT:
A thermal therapeutic seating apparatus comprises a seating structure having a first air chamber and a headrest structure having a second air chamber. A heater is operatively associated with the seating structure to heat ambient air in the first air chamber. A heat distribution structure connects the second air chamber to the first air chamber to distribute heated air by natural connection whereby heated air flows from the first air chamber to the second air chamber and back to the first air chamber. This causes the seating element and the headrest element to be heated.
