A pneumatically adjustable seat includes a seat frame having a seat back frame portion and a headrest coupled to the seat back frame portion. The headrest includes a resilient cushion. A drive assembly includes a contact member operatively associated with the resilient cushion. A first bladder is operatively coupled to the contact member and in fluid communication with a source of pressurized fluid. Inflation of the first bladder via the source of pressurized fluid extends the contact member from a first position nearer the seat back frame to a second position further from the seat back frame. A second bladder is operatively coupled to the contact member and in fluid communication with the source of pressurized fluid. Inflation of the second bladder via the source of pressurized fluid pivots the contact member away from an occupant of the seat.
