The furniture. Instructions for assembly could be greatly improved if drawings displayed front and back surfaces. For furniture itself: as I was constructing, I needed to move a shelf.  I lifted it from floor, and a short divider piece broke off without out any outside contact.  It had 2 wooden dowels in place and 2 metal rods holding it perpendicular to board I lifted. I broke away shredding part of the divider section.  Very disappointed. As a result, I have been stalling completing the cabinet. Disappointed.
