An expandable chamber support system for vehicle seat and mattress applications includes an expandable chamber constructed from facing sheets of flexible impermeable material that are sealed along their marginal edges. An upper one of the sheets is formed of electrically conductive elastomeric membrane that is electrically resistance heated while cooperating with a lower one of the sheets to provide pressure support for an occupant supported by the expandable chamber.
