Putting the bookcase was not hard just time consuming, the manual was helpful
I love the way it looks in my living room. 
The only con I have is the  cardboard peice that covers the back was not cut right, too small and not even, and it was difficut to put on I used the nails provided but they didn't work and I chipped the bottom of the peice. I would have preferred the cardboard back to be too large and been able to connect it with glue.
