SEAT AND METHOD OF ADJUSTING A SIZE AND COMFORT OF THE SEAT

A seat includes a seat frame, a seating surface supported by the seat frame, and a comfort system disposed between the seat frame and seating surface. The comfort system includes a bladder transitionable between an inflated condition and a deflated condition such that the bladder has a variable size and a variable firmness. The bladder defines a cavity and includes a lower surface adjacent the seat frame, and an upper surface opposite the lower surface and configured to support an occupant of the seat. The comfort system also includes a foam disposed within the cavity, wherein the foam contacts the upper surface when the bladder is in the deflated condition. The comfort system also includes a pump configured for alternately introducing air into the cavity and throughout the foam and removing air from the cavity and the foam to transition the bladder between the inflated condition and the deflated condition.
