Kennedy needed a stool because of his bad back.

Stools might be just as bad for Hillary, as she'd have to get off and on it repeatedly, and maintain her balance while sitting on it. A conference table is her best bet.

That said, no debate had the same format for all three. It would be bad to let her hide behind a table for all three debates. Usually, they have a format where the candidate can walk around and relate to the audience.
