Abstract
A chair has a supporting frame, a seat portion for supporting an occupant, and a back portion for supporting the back of a seated occupant. The portion is reclinable relative to the supporting frame between a generally upright position and a generally reclined position. A preference control is operatively engaged between the back portion and a chair component, wherein displacement of the back portion toward the generally reclined position causes displacement of the chair component. The preference control is adjustable to vary the amount of displacement of the chair component caused by a given amount of displacement of the back portion toward the generally reclined position.
