This book ladder was perfect for our overflow of books.  We already had two book shelves completely filled, and this shelf was perfect for our small space.  It’s very sturdy, not very hard to put together, and aesthetically pleasing.  It was a little difficult for me to tell, from the pictures, that it is very grey.  But that turned out to be okay.  It definitely has an industrialmodern look to it, but it worked okay where we put it. It’s a nice solid bookshelf!
