Abstract
A chair having a one-piece molded shell including a seat and a backrest that can recline relative to the seat. One or more flexible elements are mounted to the seat such that the flexible elements restrict the inward flexing of the seat as the backrest reclines. The flexible elements are positioned to allow the initial flexing of the side edges of the seat as the backrest reclines relative to the seat. A stop member is positioned relative to the flexible elements such that the stop member limits the amount of movement of the flexible elements. The flexible elements are located between the seat and the base. The flexible elements exert a bias force on the side edges of the seat to urge the backrest to return to an initial position when a reclining force is not longer exerted on the backrest.
