ABSTRACT:
Chair support pivotably carries parallelogramic support arms which are pivoted to seat rails. One of the support arms continues above the seat rail to become an arm support and adjacent the top thereof carries one end of a telescoping unit. The other end of the telescoping unit is pivoted to the seat rail. The telescoping unit is of such length that, when the support arms are in the erected position, the telescoping unit bottoms out to become a rigid compression member and provide a firm, erected position.
