'bedframe' originates from English as a compound of two older words: 'bed' (from Old English 'bedd', meaning 'sleeping place') and 'frame' (from Middle English 'frame', ultimately from Old French and Proto-Germanic roots meaning a support or structure).

'bedframe' developed in Modern English by compounding 'bed' + 'frame' (earlier English used forms like 'bed-frame' or related terms such as 'bedstead' to describe the supporting structure). Over time the hyphenated or two-word forms coalesced into the single compound 'bedframe' in some usages.

Initially the elements referred separately to a 'bed' and a 'frame'; combined, the compound has long meant the physical support structure for a bed and has retained that core meaning into modern usage.
