I found mine unfurnished outside of the Salvation Army and we had to tie it to the roof of the car to get it home! When I moves I discovered there are only 6 screws holding it together.
The thing with the house is there's more headroom than with a book shelf. A few of my guys, like Nicholas Holmes and Toshi, would have to stoop to enter some book shelves. On the bookshelf side I actually use a heavy duty garage shelf. I have a lot of big books.
