Abstract: A reclining chair system operable about different modes. The reclining chair includes a base, an intermediate member, left and right side frames, a support chassis, and a footrest. The intermediate member has opposite left and right sides, and is mounted onto the base so as to be rotatably moveable with respect to the base via a corresponding rotating assembly so as to operate the reclining chair in a rotating mode. The left and right side frames are operatively mounted respectively onto the left and right sides of the intermediate member via a corresponding rocking assembly so as to operate the reclining chair system in a rocking mode. The support chassis extends between the left and right side frames for operatively supporting a seat and a backrest of the reclining chair system.
