Abstract
A collapsible bedding foundation comprises a rectangular base frame and a rectangular wire grid. The wire grid is hingedly supported upon the frame for movement between a collapsed position and an erect position. The hinged connection between the wire grid and the base frame is achieved by a plurality of transverse spaced, parallel planar support elements pivotally connected to the base frame and the wire grid. The foundation is supported in an erect position solely by a pair of longitudinally extending, parallel planar support elements pivotally connected to the longitudinal edge of the wire grid and, when the foundation is erect, fixedly secured to the base frame.
