The assembly directions are vague and there were two leg extensions in the box, at least that's what they seem to be. The directions did not include what to do with them. Or why two and not four - the table has four legs, right? There were some other pieces of metal that weren't explained. Once assembled, the table is sturdy and works for me, but the legs are open-ended, sharp edged at the bottom. That seems odd and could damage flooring.
