A bleacher seating system provides a compact, automatically extending and retracting set of seating rows, where each seating row can be set at two or more different heights or slopes to provide different sightlines for spectators of different events. The bleacher seating system may be extended, retracted, raised, and lowered by a single operator, and may be retracted into a compact storage configuration, such as a configuration that is only about two seating rows in depth. The seating rows are independently raised and lowered by lift mechanisms, which include lock mechanisms to stabilize and lock each seating row at the different preselected heights. Optionally, a controller is provided for coordinating the powered extension, retraction, raising, lowering, and locking sequences of the seating system.
