ABSTRACT:
A back construction includes a base with a yoke formed by a cross member and upright side arms that define a U-shape, armrests supported by the side arms, and a seat and back also supported by the side arms for synchronized motion upon recline of the back. Specifically, the side arms define a back tilt axis about which the back rotates upon recline. The back includes a back structure with configured ends that engage the side arms for rotation about the back tilt axis, and further define a seat tilt axis for supporting rotation/movement of the seat upon recline of the back.
