A unifoldable reclining chair design has a collapsible articulated frame and includes a pair of opposing side assemblies having longitudinally elongated pivotally connected side frame members that are maintained in opposing transversally spaced relation by front and rear collapsible X-shaped connector assemblies. Slidable pivot connections, or alternatively, pivotal connecting linkages, which join the rear connector assembly to associated side frame members, enable all of the frame members to move substantially in unison and in multiple directions relative to each other while simultaneously undergoing multiple changes in an angular position relative to each other to move the chair frame from a set-up condition for use to a collapsed condition for transportation and / or storage in response to a single folding action. The slidable pivot connections and pivotal connecting linkages also enable a chair occupant to change the angular position of the chair back support when seated or reclined in the set-up chair.

A reclining chair includes a seat, a backrest, and a pair of spaced apart recliner mechanisms cooperatively supporting the seat and backrest. Each of the mechanisms includes a ground engaging base link, a seat link operably coupled with and supporting the seat, a backrest linkage operably coupling the backrest to the seat link, a rear swing link operably coupled to the base link at a first pivot, and a front swing link operably coupled to the base link with a shiftable pivot mechanism defining a second pivot. The rear swing link and the front swing link are selectively pivotable about the first and second pivots respectively to enable the mechanism to be selectively shifted between an upright position and a reclined position. The shiftable pivot mechanism shifts a position of the second pivot relative to the base link as the mechanism shifts between the first position and the second position.

Provided is a linkage mechanism for a recliner that includes a seat-mounting plate, a base plate that is vertically supported by one or more legs, a footrest assembly adapted to extend ottoman(s) when the recliner is adjusted from a closed to an extended position, and a front lift assembly.
