The first bookcase took a while longer to assemble.  The crossbars in the back of the bookcase were a puzzle for about 15 minutes.  Then realized the part of the piece was higher than the other in the middle. It took about 2.5 hours to get used to the screws and read the instructions.  
The second bookcase about an hour and a half,
With some interruptions.  So much better.
It looks very classic and is a sturdy bookcase.
