The work table shelves arrives quickly and nicely packed.  Each metal shelf had a layer of film to prevent scratching but only ran down the middle.  Assembly was about 30 min per table.  I would note that the lower shelves a bit smaller than the top work surface -- the photo shows that you could add pots and other equipment to the lower shelves with plenty of room to spare.  I was able to put a large item and a small item on each shelf without being cramped.  If you are looking for extra storage for glassware, dishes, spaces and other small to mid sized items you would put in upper cabinets, then these are GREAT!  If you are trying to store larger items like InstaPots, baking sheets and large pans, you should go up a size.
