Hi all,

I live in an old brownstone where the floors of each room have a slope one way or the other. I am renovating my kids' rooms and would like to install these type of bookshelves. They are mounted on the wall but sit on the floor. Any ideas of how I can safely and aesthetically level the unit on the floor such that it could be sufficiently supported? thank you!
