I love this bookcase. I'd purchased a ladder bookcase from a big box store that was mdf instead of real wood.  It was in pieces by the time I got it home.  I looked on line and found this beauty.  Putting it together (1 woman and her tools) was easy and took no more than 1 hour to 1 1/2 hour.  I have heavy books on the bottom shelf and various knickknacks on the upper shelves.  Heaviness does not seem to be a problem.  I also like the design of this piece.  It's very sleek.  This piece seems as if it will endure for a long time.  I am extremely happy with this purchase.

ETA: Four months after initial purchase, I still love this book case.  It is a great storage piece as it can hold a lot of items.  The book case stands on hardwood floors in my home.  I haven't had any issues regarding sliding as other reviewers described.

Pros: Price, easy assembly, appearance
Cons: none.
