ABSTRACT:
A seating system having a plurality of seating sections in which the slope of the understructure thereof can be varied, the treads of the seating sections being pivotable to permit the riser height to vary so as to enable a single seating system to provide varying slopes and sight lines depending on the stadium/arena configuration. The treads are pivotable between low riser and high riser positions by the provision of lever arms movable between angular and upright positions and extending between the treads and the beams for supporting the treads in the high riser position on the upper surface of understructure beams. In the low riser position ends of the treads opposite their pivotal ends are supported on an adjacent tread.
