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