This bookshelf can be used as a stand alone assembly OR could be installed on to the wall. Hardware is included for both options. I opted to use this as a standalone assembly. For this, two blocks are included which need to be attached to the two hind legs of the bookshelf. This prevents the bookshelf from tipping over.
