This shelf is very sturdy and perfect for our home library. We have a lot of hardcover books, but there is plenty of space and I'm not worried about the shelves bowing. There aren't embellishments at the top or bottom that would hinder lining a wall with these shelves. We're very happy with our purchase. 

Pros: Easy assemblage, clean lines, can place multiples right next to one another
Cons: Got a few nicks in transport, but nothing significant.
