ABSTRACT OF DISCLOSURE A reclining chair movable between a normal position wherein the seat extends generally in a horizontal plane and the backrest extends generally in upright position; and a plurality of reclining positions wherein the seat extends at an incline relative to the horizontal and the backrest extends at an angle to the vertical. For purposes of styling as well as to provide effective back and head support depending on the position of the chair, the backrest is formed in two parts including a primary backrest and a secondary backrest which moves from a retracted position behind the primary backrest when the chair is in the normal position, to an extended position beyond the backrest when the chair is moved into what is known as the T.V. position which is a reclined position intermediate the normal and fully reclined positions. Pivotally mounted for movement relative to each other, the backrest and the seat are supported relative to a fixed frame which includes the armrests and the chair base, by means of a balancing link pivotally mounted relative to the frame. Additionally included in the chair is an extendable and retractable footrest including a main footrest for supporting the feet and a secondary footrest for supporting the calves. The footrests are included in a constrained linkage system one end of which is pivotally mounted relative to the seat to be automatically actuated between a fully retracted position hidden under the seat when the chair is in the normal position, and a fully extended position projected forwardly from the seat when the chair is moved to the T.V. position. Actuation of the footrest is achieved through relative movement of the seat and the balancing link which during this phase is restrained against movement relative the the stationary chair frame. Mounting and actuation of the secondary headrest is achieved through a linkage connected to the frame and the primary backrest which is connected to the seat and the balancing link. During movement from the upright to T.V. position, the balancing link is restrained against movement relative to the frame, and the seat and backrest moved together into a reclined position. Continued reclining movement beyond the T.V. position frees the balancing link for movement while also causing the primary backrest to pivot into further reclined position relative to the seat which movement together with the freedom of the balancing link causes the seat to be moved into a further elevated reclining position. When moving between the T.V. and fully reclining position, the secondary backrest undergoes a slight reverse movement to relieve the angle between the secondary backrest and the primary backrest for comfort purposes.
