ABSTRACT:
A seat (3) in a chair (1) is suspended by two swingable links (4, 5) to be swingable with respect to a base (2) with legs (6, 7) and a seat holder (12). The distance or spacing (S2) between lower ends of the two links (4, 5) is changeable or adjustable so that the links extend in parallel to each other or the links extend at an angle to each other, thereby varying a swinging mode of the seat (3). For this purpose the lower ends of the two links (4, 5) are connected to two sliders (21, 22) which are guided and operable to move in directions toward each other or away from each other, respectively.
