ABSTRACT The chair according to the invention comprises a supporting base (C), a seat (1) and a back (2) operatively connected to the seat so as to be able to be moved from an upright position to a reclined position. The chair is of the type including a linkage system (3, 7, 9, 11) forming an articulated quadrilateral in which the seat (1) is supported by a substantially horizontal upper side and the back (2) is secured to a side articulated at one end (3) to said upper side and at the other end (7) to a lower side carried by the said supporting base (C). The said articulated quadrilateral is different from a parallelogram, i.e. it has at least two opposite sides which are not parallel to each other, whereby the movement of the back (2) to its reclined position will cause the rearward displacement and lifting of the front of the seat (1) and the rearward displacement and lowering of the rear of the said seat.
