This invention discloses a novel and improved chair control for tilting chairs wherein the mechanism which controls the tilting of the chair is simplified and strengthened. It utilizes a bolt having an elongated head of V-shaped cross-section as the biasing means between the seat portion and the moveable frame portion. Stopping means are provided which reduce the pressure applied to the frame portions when the seat returns to a resting position, the means comprising a series of vertical and horizontal surfaces on each vertical side wall of the fixed frame portion which contact the moveable frame portion. Also provided is an improved feature to strengthen the control whereby the inner plate of the fixed frame portion has a pair of downturned spaced apart feet inserted through the base plate of the fixed frame portion to strengthen the control when the seat is tilted rearwardly.
