Bench

Long backless wooden seat for a table, hall, or workshop.

A plank seat on splayed legs, long enough for three or four to sit at a table. Benches, not chairs, are what people actually sit on: they are cheap, they take whoever arrives, and they push under the table out of the way. In a hall the bench a person is seated on says precisely where they stand, which is why the word for the furniture and the word for the rank are so often the same.
