The invention concerns a cushioning for seating or a backrest of a motor vehicle seat having a heating layer with an electric circuit made from conductive ink. The circuit has two buses extending longitudinally, the buses are connected together by a plurality of printed microcircuits shaped so as to form resistances capable of heating the cushioning. The cushioning also includes buses made from a first ink and microcircuits made from a second ink, the first ink having a higher intrinsic conductivity than that of the second ink, or the bus and microcircuits are made from the same ink, the ink being deposited more thickly for the buses than for the microcircuits, such that the buses provide minimized electrical resistance to the flow of current.
