ABSTRACT:
The seat furniture is provided with a seat-plate backrest inclination-adjusting mechanism (6), a single-column supporting device (2) and a supporting foot (1). The backrest is composed of a backrest bottom part (16) and a backrest top part (14), and when the backrest inclination is fixed the backrest top part (14) can additionally be moved, counter to the pressure exerted by a restoring-spring arrangement (13), so as to swing freely to the rear between a first and a second stop position of an adjusting-spring device (22).
