Abstract: The present application discloses a chair capable of swinging forward and backward, including a chair leg, a seat cushion, and a compression air rod that connects the chair leg and the seat cushion, where a bottom of the compression air rod is provided with a tapered sleeve, the tapered sleeve is disposed inside a cavity of the chair leg, an outer side of the tapered sleeve is enclosed by a soft sleeve, and the compression air rod swings by means of an interaction between the soft sleeve and a cavity wall of the chair leg.

Abstract: This invention provides a chair leg including a connecting column, a sliding base, and a swinging block; the swinging block includes a positioned swinging block, a ring spring, and a fixed block; the sliding base includes a sliding leg and a connecting block; and the connecting column is fixed to the sliding base via the swinging block. This chair leg is provided with a simple structure, easy production, lower manufacturing cost, and is capable of swinging in a certain angle of 360 degrees and giving users more comfortable seat experience.

Abstract: The present application discloses a chair with a bi-directional controllable air rod valve including a chair leg, a seat cushion, and a compression air rod that connects the chair leg and the seat cushion, where two sides of a cavity of the seat cushion are each provided with a set of valve control members. The set of valve control members disposed in the cavity of the seat cushion enables a user to adjust the chair with both left and right hands conveniently, which greatly facilitates the operation, and in addition, the hidden design of the valve control members prevents the exposed valve control members from hurting a mover or a user and meanwhile, protects the valve control members.
