Abstract
An integrated chair and control arrangement is provided for tilt back chairs, and other similar seating. The chair has a base, as well as a back and a bottom or seat which are interconnected for mutual rotation about a common axis. The common axis is located above the chair bottom, forward of the chair back, and generally adjacent to the hip joints of a seated user. A control supports the chair back and chair bottom on the base in a manner such that rearward tilting of the chair back simultaneously shifts the chair back, the chair bottom, and the location of the common axis in a manner which maintains the adjacent spatial relationship between the common axis and the hip joints of the seated user to provide improved comfort and support.
