摘要： An office-type chair including a back support having a suspension mesh back support and a back support frame. The suspension mesh back support has an integral retaining channel disposed at a peripheral edge thereof, and the back support frame includes a central pair of upright support posts and wedge base for mounting to a chair frame. The back support frame includes a plurality of flexible and spaced support arms extending laterally outward from the upright support posts. The support arms each have a peripheral edge configured for fastenerless attachment in a tensioned state within the suspension mesh retaining channel. An upholstery cover encapsulates the suspension mesh and back support frame. The office chair also includes a lumbar mechanism including a resilient cushion that may be positioned in the space between the suspension mesh and the support frame and adjusted along the vertical extent of the back support by rolling the resilient cushion on the rear of the suspension mesh.
