Seater → It is formed from "seat" (from Old English "sæte", meaning a place to sit) and "-er" (meaning a person who). The word "seater" refers to a person who sits or a designated place for sitting.
Think of a 'seat' as a place to sit, and the '-er' indicates a person or thing associated with it. So, a seater is someone who sits or a place designated for sitting.
