A chair including a dynamically-flexible back and seat having a shape that adjusts to the movements of a user seated in the chair to enhance user comfort. Each of the back and seat has an air gap formed therewithin and a resilient frame or liner with a spring memory. The resilient liner is adapted to flex in response to compressive forces that are generated as the user slides his body back or from side-to-side in the chair. Accordingly, some of the chair back and some of the chair seat move into respective air gaps so that the shapes of the back and seat change to conform to the movements of the user. The air gaps also establish air flow ventilation channels which run laterally through the back and seat of the chair. In one case, a lumbar portion is rotatable back and forth around a vertical pivot axis so as to pivot towards one side of the chair back or the other side.
