We are using these shelves in our Library to hold all of our books. Once assembled, the cubes were quite sturdy, but I was a little disappointed with the quality of the material. They are made out of particle board, with a very thin white veneer. However, once assembled, put in place and filled with books, this doesn't appear to be a problem.
