Abstract
A chair, in particular an office chair, has a vertical column (12) rising from a pedestal (10). From the top end of the column a bracket (16) projects forwards. A seat (20) is connected to the bracket and is supported in the rear region by a generally U-shaped led spring (24) fastened to the column (12). The seat (20) is fixedly connected approximately in the region of its front third to a support plate (18) attached to the bracket, and in the region of its rear third fixedly to a rigid bearing plate (22). On its underside, the bearing plate (22) has sleeves for receiving, in a displaceable manner, two open ends (38, 40) of the leg spring (24). The seat (20) is designed so as to be able to move at least in the region of its middle third.
