My husband, who is a mechanic easily put this together.  The instructions  were straightforward.  When it was complete, we stood it up to find that the feet wobbled.  Upon further inspection with a level, we discovered that the base board was warped, causing the whole bookcase to wobble.  He was able to correct this by purchasing furniture pads and attaching them to the “shorter” feet (like putting a matchbook under a wobbly table at a restaurant).  Cheap bookcase.  Disappointing.
