It arrived 4 days ahead of schedule so we were very excited to get it. We budgeted 1-2 hours to assemble and put books on it. It took over 4 hours to assemble 2 bookcases, 2 people, my husband is an engineer and hobbyist furniture builder. It was also very dirty out of the box. it turned our hands black. It also scratched easily. - Loss of 1 star

It looks amazing in the room though. We have 2 side by side and they look very simple and elegant. The photo doesn't do it justice. 

Pros: looks amazing, coordinates well with many furniture styles, holds a lot of books
Cons: hard to assemble, dirty out of box, scratched easily
