A front-aisle step that is integral with a deck of a bleacher and disposed in a bleacher access-aisle is disclosed. The first deck includes a deck surface having a deck surface height above a support surface and the front-aisle step has a front-aisle step surface having a height above the support surface that is less than the deck surface height. The front-aisle step has a front edge that is co-extensive with or recessed from a forward edge of the bleacher. In one embodiment a reversible platform is disposed in the access-aisle and in a first mounting orientation provides a front-aisle step surface at a height below the first deck surface and in a second mounting orientation in which the reversible platform is inverted from the first mounting orientation, the reversible platform provides a front-aisle step surface at a height generally co-planar with the first deck surface.
