A pro active lumbar support bladder is contoured as a U-shaped plenum containing liquid silicone occupying approximately 65% of the volumetric space of the plenum, the balance of the plenum evacuated. The bladder is encapsulated either within the inside foam rubber bun, normally associated with the back of an automotive seating structure, or is an integral interior part of a seat cover assembly whereupon the seat cover with bladder is pulled over the foam rubber bun to form the seat assembly. Once installed, my novel bladder automatically adjusts to the anatomical condition of the seated occupant, regardless of size or weight.
