First, your title: the only stupid question is the unasked one! Never apologize for asking a question.

As others have said, 20 years ago, most likely it is solid wood. It iwll be heavy to move. Today's stuff is often pressed board. You can get solid wood furniture, but it is rare and quite expensive.

You can also do a quick scan on craiglist in your area to get an idea of things, but I think this is a great deal.
