These bookshelves look gorgeous, but they are a total pain to put together and I have concerns about structural stability because of the way that the base is shaped.  There is no support on the back of the shelf, it is all resting on three small 3x1 planks around either side and the front of the base.  The wood has split in several places every time the shelf has been moved, even without any books on it.  Like I said, they're pretty, and will suit my needs until they fall apart, but I certainly wouldn't recommend them to a friend and I won't be ordering more.
