A foldable stadium seat (10) is disclosed which is manufactured from a pair of first and second generally planar seat members (11) and (12), which are both products of the same mold. This is made possible by a specific configuration of hinges wherein a first hinge half of a first hinge is attached at one end of the rear edge of the seat member and a second hinge half of a second hinge is positioned at a second end of the rear edge of the seat member. Each of the hinge halves are positioned along the rear edge such that when the rear edge of a second seat member is placed juxtaposition the rear edge of the first seat member, the hinge halves on the two seat members will interfit and can be engaged by a suitable hinge pin (14). Radial stops are formed along the rear edge of both seat members (11) and (12) to provide a radial stop for the foldable single mold stadium seat (10) when it is in the open position, having a first and second seat members (11) and (12) generally perpendicular to one another.
