Abstract

An office chair (10A) includes a seat (16) and a backrest (17) that are pivotally connected together at a pivot axis (24) such that the back¬ rest (17) can pivot with respect to the seat (16) between an upright position and a reclining position. The seat (16) is mounted on a base (13) such that the seat (16) can move with respect to a base (13), and the seat (16) includes front (18) and rear portions (19) that can pivot with respect to one another. When the backrest (17) is pivoted from the upright position to the reclining position, both of the seat (16) and the pivot axis (24) move forward with respect to said base (13), and the seat front portion (18) flexes with respect to the seat rear portion (19) such that the angle between said upward faces of said seat front portion (18) and the seat rear portion (19) increases. The backrest (17) may also include an upper portion (21) and a lower portion (22) that can pivot with respect to one another. When the backrest (17) is moved to the recline position, the angle between the forward faces of the upper (21) and lower backrest portions (22) decreases.
