Abstract

A chair comprises a seat support with a front seat support part and a rear seat support part which is connected thereto via a pivoting axis. Seat inclination can be modified by means of an adjusting element by operation of a turning handle. The turning handle is connected to the adjusting element via a coupling element, with the axes of rotation of the adjusting element and turning handle not being in alignment. This ensures conveniently accessible modification of seat inclination.
