Sofabed → It is formed from "sofa" (from Arabic *ṣuffa*, meaning a long seat or bench) and "bed" (from Old English *bed*, meaning a sleeping place). The word "sofabed" refers to a piece of furniture that serves as both a sofa and a bed.
Imagine a long seat ('sofa') that can also be a place to sleep ('bed') — that's how a sofabed works.
