Abstract
A molded plastic seating module is disclosed which is suitable for assembly in groups to form bench type row seating especially telescoping bleachers. Each module is hollow and comprises two sections, a contoured seat and an upstanding base. The base is adapted to be secured to the support structure both vertically and horizontally and to resist tipping and the presence of structural stress concentrations in use. The seat is adapted to engage the base in a snap fit relation along its front and rear walls.
