A folding stage includes a folding linkage with cross members and a center lock. The center lock has a handle below the cross members and off to the side of the cross members to prevent pinching of operators' hands and fingers. The folding linkage folds from a use position wherein stage decks are horizontal to form a stage surface to a storage position wherein the bottom of the stage decks oppose one another. In the fully folded position, stage support legs are angled inward slightly. Casters mount at an oblique angle to the telescoping legs and are moved closer to the telescoping legs to decrease the moment of inertia about the legs while maintaining sufficient contact with the floor. Torsion bars mount at the pivoting access of the frame and the telescoping legs to control folding speed. The folding portions of the frame and decks have a center of gravity which is aligned with the pivoting access to decrease the moment of inertia about the pivoting axis.

[ What is claimed is:] [1.] An elevationally adjustable folding stage, comprising:a frame;a pair of stage decks having an upper surface and a lower surface;telescoping legs mounted to the frame;a folding linkage having cross links for folding the stage from a use position wherein the stage decks extend horizontally and the telescoping legs extend vertically, and a storage position wherein the lower surfaces of the stage decks oppose one another and the telescoping legs angle toward one another at an upper end; anda center lock having a spacing linkage with an inner spacing linkage link and an outer spacing linkage link extending between opposed telescoping legs, and a stop mounted to a pivot pin extending between the spacing linkage links, the stop having a handle extending above and outward beyond the outer spacing linkage link.
