Morphology

water + bed

The meaning 'a bed filled with water' is directly and compositionally derived from 'water' (the liquid) + 'bed' (sleeping furniture); it specifies the material/content of the bed. This noun–noun compounding is a regular, productive pattern in English and is cross-linguistically common, so a B1 learner who knows both constituents will readily understand it.

Etymology

Water bed comes from a real bed that uses a mattress filled with water, so the top moves a little like small waves when you lie down. That's why it means 'a bed with a mattress made of plastic and filled with water'.
