A grandstand seating arrangement having seating level members arranged in sequentially elevated relation to one another. A rigid frame that couples and surrounds the seating members has a lower frame coupled to the lifting arrangements and an upper frame coupled rigidly to the lower frame. A lower stop is disposed on each stanchion support and arranged at a height corresponding to the height of the associated seating level member. Seating level member supports support the seating level members, each of which is coupled to, and displaceable along, a respective stanchion support. The seating level member supports are supported by lower stops when the lifting arrangements are in the lower most position. When the lifting arrangements raise the rigid frame, the seating level member supports and the seating levels thereon are sequentially raised from the respective lower stops.
