A large, soft pad that is used on a bed for sleeping, usually filled with materials like foam or springs.

**Mattress** → The word originates from the Arabic "matrah" (meaning something thrown down or a place where something is thrown). It was adopted into Old French as "matrace" before entering English. A mattress is essentially something that is thrown down for sleeping or resting upon.
Imagine a place where something is 'thrown down' — that's what a mattress is, a surface you lay down on to rest.
