Love this bookcase! Arrived quickly and it took me less than 15 minutes to assemble.  More importantly, it was rock solid when I was done. Have it loaded up with a combination of books and baskets filled with stuff in the office - current load is about 80 pounds and no issues. I would not hesitate to fill each shelf with books, just no need at the moment. Am considering a second one...

Pros: Solid, EASY assembly
Cons: none
