ABSTRACT:
A bolster is moveably mounted on a seat back with a bolster adjustment mechanism adapted to adjust and control the support provided by the bolster. Preferably, the bolster adjustment mechanism is mounted on the back side of the seat back, and preferably includes a positioning member between adjacent ribs in order to form a stop limit or positioning element when contacted by the ribs. The positioning member can be a variety of structures, such as structures of different dimensions, hardnesses or compressibility.
