Abstract: A folding seat includes a pair of side frame members joined by detachable rungs. Each side frame member has an arm, a front leg and a back leg. One of the legs is pivoted directly to the arm, while the other leg is pivoted to the arm with a sliding link which locks with the arm when the seat is erected. A web is slung between the rungs to support a person sitting in the seat and is detachably held in place by rods which register with slots in the rungs.
