The directions do not tell you to look for the tiny, pre-drilled holes for the back panels. I accidentally put those toward the front, so now some shelves has a little hole on the front that snags dust cloths, gives splinters and looks bad. I was only able to get two of the back panels in once I caught my mistake, so my center cubbies are open to the back wall. I still like the color. The cubbies are just the right size for record albums and I put my turn table on top with shelf speakers in the cubbies. It looks good from a distance.
