Etymology: "Backrests" is simply the plural of "backrest," a compound formed from "back" and "rest." The parts are plain: "back" is the rear of a body or object, and "rest" is a support on which something leans or lies. Put together, the term names the support a seated person leans against, which is why it describes the rear part of a chair or similar seat.

Synonyms: support backs, lumbar supports
