A person needs a GREAT deal of patience to put this shelving unit together and get it hung up properly. Instructions were terrible. It needs to come with a template to make it easier to know where to place the holes on the wall. It is literally impossible to hold the shelving unit up to the wall to mark where the holes need to go without the shelving unit coming apart in the process. . Hanging this takes (3) people.  Two to hold it against the wall and a third to take the measurements.  Also the equipment supplied to attach the unit to the wall was flimsy.  We needed to use sturdier items to get this hung.  That said, once it was up—it looks nice and works well in the space.
