Abstract: The present disclosure relates to the technical field of chairs, in particular to a zero-gravity and zero-wall chair frame including a base, a seat side plate assembly, a first linkage assembly, an ottoman assembly, a driving mechanism arranged on the base, a second linkage assembly, a backrest assembly and a first driving rod connected with the output end of the driving mechanism. The seat side plate assembly and the second linkage assembly cooperate to drive the backrest assembly to move away from the wall while unfolding, and the backrest assembly will not interfere or conflict with the wall during unfolding or reclining, thus realizing the zero-wall clearance placement of the chair frame in a closed position and saving the placement space of the chair frame.
