The bookcase looks fantastic and we've had positive comments from guests.

It was easy to put together - although I would advise using an electric screwdriver as there are lots of bolts to fit.  I only had two issues. 

Firstly, some of the pieces were incorrectly stickered - piece 1 in my case. Not the end of world as it was pretty obvious from diagram which one was which.

Secondly, some of the pieces have recessed edges to bolt hole. It is a good idea to check which side has recess in so when you're inserting bolts the bolt doesn't leave a head above the wood plane.
