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.
