A tilt back chair provides for selective independent and concurrent movement of a chair back with respect to a chair seat. The seat is mounted to a spring biased bracket for pivotal movement about a seat tilt axis. The back is connected to a pair of pivot brackets projecting upwardly from the seat to provide for pivotal movement about a back tilt axis located above the seat and rearwardly of the seat tilt axis. When the seat is in a neutral seating position it can tilt downwardly at its forward edge about the seat tilt axis. The back is biased for displacement with the forward tilt of the seat and is tiltable rearwardly independently of the seat. The seat can also be locked in a fixed position.
