Abstract
Seating for a telescoping row system or the like is mounted to a beam pivotally secured to a base anchored to the platform and riser. The beam is raised arcuately into a use position by a pneumatic bellows and is mechanically locked in the upright position to permit deenergization of the bellows. Reinflation of the bellows disengages the lock and the assembly collapses slowly against the controlled deflation of the bellows. The seat is positionable on the beam initially without fasteners to facilitate installation. In similar fashion, armrests are secured to the beam separate from the seat and adjustable along the beam to permit overall width variations.
