Placemat vs. Tablemat — What's the Difference?

A placemat or table mat is a covering or pad designating an individual place setting, unlike the larger tablecloth that covers the entire surface. Placemats are made from many different materials, depending on their purpose: to protect, decorate, entertain or advertise.

(rare) A cushion or stiff material placed on top of a table, underneath a tablecloth.

A protective table mat for a single setting of dishes and flatware.
