This is a nice printer station for my classroom. The three shelves on the side will not support anything whatsoever unless they are screwed into the frame. I was hoping to just use the pegs without permanently screwing them in. The pegs fall out immediately and drives me crazy! I liked the idea of adjusting the shelves whenever I need to, but I can't use that feature until they are permanently secured. Overall, this is a great piece for the intended space.
