Abstract: An apparatus may include a top side, and support structures spanning a length across at least a portion of the top side. The apparatus may include: a first lateral side, connected to a first edge of the top side; a second lateral side, connected to a second edge of the top side, opposite the first edge of the top side; and a third lateral side, connected to a third edge of the top side and connected to the first lateral surface and the second lateral surface. The top side, the first lateral side, the second lateral side, and the third lateral side may define a cavity. The apparatus may include a shelf, connected to an inside surface of the third lateral side and a crosspiece, positioned such that the crosspiece supports at least a portion of the shelf when a vertical load is placed on the shelf.
