A heater system for an aircraft seat includes a first heater pad secured to the bottom seat cushion and a second heater pad secured to the back seat cushion, with both pads being under an upholstery cover. The first and second heater pads each has a body of an open cell foam material that is self flame extinguishing, and an electric resistance wire embedded in a winding pattern within the body. A control module applies a variable electric current to the electric resistance wire in each of the first and second heater pads. Preferably only the second heater pad for the back seat cushion can be activated or both the first and second heater pads can be activated. A pushbutton switch module allows the seat occupant step the control module through a sequence of different heating levels.
