Abstract: A mobile folding stage unit has right and left platform sections pivotably mounted in side-by-side relation to a frame, corresponding sets of roller wheels mounted to the frame, pivot brackets mounted to the bottom of the platform sections, support brackets mounted to the frame to which the platform sections are pivotably mounted via the pivot brackets, and pivot legs pivotably mounted to an eccentric position on the corresponding pivot brackets and slidable in pivotable bearing guides mounted to the frame adjacent the corresponding roller wheels. When the platform sections are folded to the vertical position for storage, the pivot legs are lifted above the wheels, and when they are opened to the horizontal position for use, the pivot legs are lowered to lift the wheels out of contact with the ground.
