Abstract
A vehicle seat includes a cushion having a coverstock defining a seat surface with a flexible central region and a flexible edge region. The vehicle seat further includes a compressible edge bladder beneath the coverstock edge region and a first compressible inflation bladder positioned beneath the coverstock central region and in fluidic communication with the edge bladder. A first fixed quantity of a flowable medium is contained in and partially transferrable between the edge bladder and the inflation bladder.
