Abstract
A staging and seating understructure which provides a base frame for a multiplicity of support panels. The base frame consists of a series of vertical cross frames, usually having different levels, each cross frame being connected to another cross frame by collapsible gates at each end which fold inwardly to allow movement of the cross frames close toward each other wherein the entire base frame assembly may be stored compactly.
