Abstract

A chair includes a deformable seat shell forming a seat part and a backrest, and further includes a frame, the seat part being connected to the frame by means of a first pivot joint and the backrest being connected to the frame by means of a second pivot joint, the pivot joints allowing a twisting of the seat part and of the backrest relative to the frame caused by a deformation of the seat shell. The second pivot joint is connected to the backrest centrally in relation to the transverse direction of the chair.
