ABSTRACT OF THE DISCLOSURE The seat of a chair is mounted on a post or other supporting member by a seat mount which permits the seat to tilt forward ( front end down) to a forward and downward rake of about 4-1/2°. A bracket connected to the seat and located under generally the center of the seat pivots on an axle that is received and supported by a mounting plate rigidly fastened to the supporting member. Springs compressed between the mounting plate and the bracket restrain the seat from tilting down, and co-engageable stop surfaces associated with the bracket and mounting plate limit the extent of tilting of the seat (both forward and backward raker when the latter is provided for). By joining the mounting plate and bracket by parallel front and rear axles fixed to the bracket and arranged to disengage axle-engaging surfaces on the plate, or vice versa, the seat can tilt both forward and backward; in this mode, the seat pivots or rocks on one axle, and the other axle disengages the axle-engaging surface. An optional movable blocking element can be included to disable the rearward tilt mode when disired. -1- 1827
