A workpiece support assembly, comprising:

• a pair of support members having upper ends, the pair of support members being pivotally connected to each other and movable between an open operative position and a folded position;
• an elongated workpiece support structure mounted to the upper ends of the pair of support members in a generally horizontal spaced relation above a ground surface, wherein the elongated workpiece support structure includes a workpiece support surface;
• and
• a tabletop assembly including a tabletop with a tabletop surface and a tabletop support structure connected to the tabletop and one of the support members,
• wherein when the pair of support members are disposed in the open operative position, the tabletop assembly is movable between a deployed position in which the tabletop is disposed substantially horizontally over the workpiece support surface and a storage position in which the tabletop is disposed below the workpiece support surface so that the workpiece support surface is accessible for supporting a workpiece.
