This is the best bookcase I have bought in a long time.  It is made very well.  Just love it!  It was easy to put together.  I was VERY impressed with the instruction.  Other companies need to take a lesson on how to write/demonstrate instructions.  These were easy to follow and it only took me 1 and a half hours to put together.  
I am thinking about buying another.  It is one awesome bookcase!!
