The invention relates to a chair, in particular a work or office chair, comprising a seat (5) mounted onto a chair frame (13). The front region of said seat can be inclined about a horizontal, pivoting shaft (15) which is displaced upwards and downwards, following a spatial guide curve in relation to the chair frame (13). Said seat is also connected in an articulated manner to a rocker (7) which is directed upwards and extends backwards from an articulated rocker bearing (12) fixed to the chair frame and which is connected at a distance from the rear edge of the seat, or at the side of said seat (5). The chair also comprises a backrest (4) which is attached to the section of the rocker (7) that is directed upwards, the inclination of said backrest being disproportionately altered, in a forced manner, with the alteration of the inclination of the seat (5). The invention aims to achieve an increased apex angle between the backrest and the seat, together with a uniform displacement. To achieve this, the backrest (4) is coupled to the rocker (7) by means of a coupling point (9.1) and the seat (5) is additionally coupled to the backrest (4) by means of a control lever assembly (8, 10), which is used to incline the backrest (4) backwards in relation to the rocker (7), when the seat (5) is inclined.
