What a piece of junk.  DO NOT BUY THIS.  I thought for the price I would at least get something sturdy.  As mentioned by other purchasers, the back of the bookcase is just a piece of cardboard covered in wood paper and held together by tape.  The directions are unintelligible, referring to the piece of the bookcase by letter - ignoring that there are not letters on the b\pieces themselves.  The "predrilled" holes are in the wrong places and even when I had gotten two pieces together properly they were loose.   This bookcase should have cost about $79.95.  It is upstairs right now held together by tape and hot gun glue.  I have purchased and assembled several pieces of furniture, including other bookcases.  If it was not so difficult I would return this one immediately.  And I am sure they count on that.  But I want to save others.  DO NOT WASTE YOUR MONEY.
