A foldable seat for a bleacher seating arrangement includes a seat or seat structure fixedly disposed at a deck portion and a back portion or backrest pivotally disposed at a rear portion of the seat portion. The back portion is pivotable between an upright position, where a person may sit at the seat structure and may lean back against the back portion, and a folded down position, where the back portion may lay generally on top of or at least partially over the seat structure. The back portion may be pivotally mounted to a mounting frame or element fixedly secured relative to the deck portion and may be substantially freely pivotable between the upright and folded down positions. The bleacher seating arrangement may include a plurality of deck portions that may be retracted to a nested position when the backrests or back portions are in their folded down position.
