The reason I emphasize the possibility of chipboard is that it is so heavy, and so poorly made, that it is a major reason people who move usually leave their entertainment centers behind, or smashed up on the sidewalk. They get wobbly almost immediately and they are too heavy to move. Plus, cedar lining or not, moisture + chipoboard = disaster. It might be just plain ol wood. But again, I refer you to the two keys to aging above. There are many more, but these are a good start.

And if Bobby thinks it's COOL, run like hell in the opposite direction!
Couldn't resist...sorry Bobby.
