A working chair has a stand (1), a seat (2), which is mounted on teh stand, and castors (5), which are mounted on teh stand to allow movement of the chair on a floor. A foot-operated tipping support (6) is mounted on the stand (1). The tipping support (6) is movable between a raised inactive position, in which it is situated at a distance from the floor and allows movement of the chair on the floor, and a lowered active position, in which it abuts against the floor and renders movement of the chair on the floor difficult. The seat (2) is pivotable between a substantially horizontal sitting position, in which a user can sit on the seat (2), and a substantially vertical support position, in which the user, while standing on the tipping support and thereby keeping it in its lowered active position, can lean against the seat (2). |
