The Classic Pro base has a heavy duty professional brace which fits between the table legs. This allows the shelf to slide forward to retrieve items or reference material that can be slid back out of the way when not in use. Base is available in black or white. On top of this base is a Martin Drafting Board Top made of solid high density pressed wood covered with white laminate. The shelf is the same material. The shelf and brace can be removed to fold the table for easy storage.
