I'm avoiding particle board. I don't have an Ikea and I think all of the other places here have the particle board shelves. But I can make shelves and put them together-but since I'm planning to make the whole thing I can do it the exact sizes I want. I can use wood or mdf which is not as stinky or chip-py as particle board. I was just hoping for tips or pictures of ones people have made themselves with or without store bought shelves, but without the space underneath for a chair.
