Chair comprising: - a support base (12), - a seat (14) including a support structure (38) that is movable relative to the support base (12) between a lowered position and a raised position, and a backrest (16) having a support structure (22) articulated to the support base (12) around a transverse axis (28) and oscillating around said axis between a position of maximum forward inclination and a position of maximum backward inclination, in which the seat (14) and the backrest (16) are mutually connected in such a way that when the backrest is in the position of maximum forward inclination the seat is in the lowered position and when the backrest is in the position of maximum backward inclination the seat is in the raised position. The support structure of the seat (38) is connected to the support base (12) by means of at least one rocking lever (58) articulated to the support base (12) and to the support structure of the backrest (38) around two mutually parallel transverse axes (60, 62). The support structure of the backrest (22) comprises two lateral sections (26) each of which has a connecting portion (34) that extends beyond the axis of articulation (28) of the backrest (16) to the support base (12), the connecting portions (34) being articulated to the support structure of the seat (38) around a transverse axis (56) displaced forward relative to the axis of articulation (28) of the backrest (16).
