Provided is a chair in which the rear section of the seat can be raised with good lateral balance, in which the seat is stable, and that has a simple structure and a good appearance. The disclosed chair includes a seat (6) that is pivotally attached by means of a laterally-oriented pivot shaft (9) to a support base (5) supported by (a) leg(s), the rear section of the seat (6) being pivotable in the vertical direction. In said chair, an urging means (12) that urges the seat (6) upward is constructed so as to include: an elastic expanding-and-contracting component (13) that connects a portion of the support base (5) located below the pivot shaft (9) and a portion of the seat (6) located to the rear of the pivot shaft (9); and a pair of leaf-spring-like elastic warping components (14) provided on the right and left sides of the elastic expanding-and-contracting component (13).
