Abstract
An office chair has a back with a central portion and respective wings or bolsters on opposite sides of the central portion. The wings are coupled to the main central portion by arm structures that are designed to allow the wings to flex rearwardly from a rest position and back to the rest position in response to forces exerted by a person seated in the chair, but to resist forces tending to move the wings forwardly from the rest position.
