Abstract
A stackable folding chair has a seat and a back pivotably attached to the rear edge of the seat. Front legs are pivotably attached at right and left edges of the seat. Rear legs are pivotably attached to the bottom of the seat. Armrests are pivotably attached to the seat back and adjustably attached to the front legs. The rear legs are pivotable relative from an extended position a folded position in which the rear legs are substantially parallel to and beneath the seat. Adjustable attachment of the armrests to the front legs allows the angle of the seat back to be adjusted as well as enabling the front legs and seat back to fold substantially parallel to the seat. The stackable folding chair preferably injected molded from plastic.
