Adjustment device (1) for a chair which is provided with a rocking mechanism composed of a first plate (2), which is fixed to a central gas-operated post (7) for the height adjustment of a seat and to which a second plate (10) is articulated, about a first axis (9) that is transverse thereto and so that it can rock, the second plate being fixed to a seat or being integral with a seat and interacting with means (8a, 8b) which are adapted to contrast the rocking of a backrest. A first cable (12) is slideably associated with the first plate (2) and is adapted to activate a lever (13) which is articulated internally to the first plate (2) at a different second axis (14) and is adapted to activate the height adjustment of the seat. A second cable (20) is further slideably associated with the first plate (2) and is adapted to activate a mechanism (21) which allows or prevents the rocking of the second plate (10).
