Abstract
A banquet chair comprises a seat and a backrest carried by a plurality of legs. A pair of arcuate leaf springs flexibly couples the backrest to the plurality of legs. The pair of arcuate leaf springs is spaced-apart, and each is located closer to a different outside edge of the seat and the backrest than to each other or a middle of the seat and the backrest. Each of the pair of arcuate leaf springs has an outermost edge exposed through a lateral perimeter of the backrest.
