The office chair has an anatomically designed seating surface and backrest and an undercarriage supporting these parts. The chair constitutes an improvement to the extent that, during sitting, it is possible, by means of massage of the back areas of the person sitting on the chair, to increase this person's well-being. This is achieved by means of the backrest being provided with an electrically operated vibrator or being designed as a vibrating massage cushion. <IMAGE> |
