Many, many screws, cam and dowels. Cams did not fit predrilled holes in places. Had to drill extra depth or remove dowels to allow boards to fit together without spaces between.  The support board underneath fell off. The screws to catch the cams keep falling out and do not catch the cams. All in all, an inferior product. I have it cobbled togther but if it's moved, it will have to be reassembled as cam screws and bottom support fall off in transit.
