ABSTRACT:
An office chair has a seating element with an upright tubular element (3) and a base, the seating element being connected to the base by means of the support element (1) so as to be swiveled and reset. Rubber buffers (19, 24) are provided between a connecting element (2) of the base, ring discs (11) and (17) and a tubular element (8) extending from the seating element downward and allow an oscillating movement of the seating element. The rubber buffers at least partially enclose the connecting element (2), thereby retaining the same. A pneumatic spring (4) allows to adjust the height of the seat. A thumb screw (16) allows to adjust the restoring force by compressing the rubber buffers (19, 24) to a greater or lesser extent.
