Abstract
A seat assembly is provided with a seat bottom and a seat back extending upright from the seat bottom. At least two side bolster seating surfaces are spaced apart laterally on at least one of the seat bottom and the seat back. A bolster support assembly is provided adjacent each of the two side bolster seating surfaces. Each bolster support assembly has an air bladder and a rigid support mounted to the air bladder and positioned between the side bolster seating surface and the air bladder. When the air bladder is in an inflated position, a contact width of the rigid support along the bolster seating surface is greater than a bladder width.
