Abstract
The chair according to the invention has a seat, a backrest, a support frame, and at least one S-shaped leaf spring. The S-shaped leaf spring at a first section is fastened to the support frame, the seat is mounted at a second section, and the backrest is mounted at a third section. A first curvature is provided between the first and second sections, so that in a neutral position of the chair the first section and the second section are situated essentially in parallel to one another and are spaced apart, and the third section adjoins the second section via a second, opposite curvature. A compressible spacer that is displaceably guided in the longitudinal direction of the first section is provided between the first and the second section.
