Abstract
A seat assembly is provided with a seat bottom having a seat frame. An air bladder is mounted to the frame. A seat cushion is spaced vertically from the seat frame by the air bladder at height-adjustment distance being variable. The cushion defines a seating surface. A height-adjustment distance between the frame and the seating surface is increased as the air bladder is inflated, thereby adjusting a height of the seating surface without adjusting the frame.
