Old factory drawers. Old dresser - pull out drawers and use to make underbed storage with wheels and then use baskets. You could either keep the shell in your room or on the landing then use the drawers under kids bed on wheels painted up.
love this idea, except for the coffee table part and only because the bookcases are too tall. It's a coffee table, an old bookcase, and some paint. Use a plain bookcase and add crown molding to the top and trim down the front.
