Abstract The work chair is provided with a backrest support (13) which is connected movably to the seat shell (4) or respectively to a base plate (10) stiffen- ing the latter, for the purpose of individual adjustment of inclination, and is flexible in terms of bending along its vertical extension and the contour curve of which, under load, essentially approximates to the curve of the human spinal column. The inclination of the backrest can be fixed by means of a locking arrange- ment (14) which consists essentially of a pawl (16) which is spring-loaded (20) and of an engagement toothing (17) provided at the lower end of the backrest support (13).
