A multi-position headrest for a chair and a mechanism for the headrest. The headrest can move between a forwardly tilted position and a non-tilted position. The headrest is supported by a multi-position bracket assembly. The bracket assembly includes two bracket members, one of which has an arcuate slot and the other of which has a mounting member adapted to move along the arcuate slot. A catch member is mounted for rotation on the mounting member. The catch member has angled edges at each end. As the mounting member moves along the slot, the catch member is rotated by contact with a shoulder and an alignment stop between orientations in which it engages the shoulder, establishing the forwardly tilted position, and orientations in which it does not engage the shoulder, allowing relative pivotal movement of the bracket assembly to return to the non-tilted position.
