Bed-mould

Bed-mould, in architecture, is a kind of moulding found under the cornice, of which it is a part.[1] Similar to crown moulding, a bed mould is used to cover the joint between the ceiling and wall. Bed moulds can be either sprung or plain, or flush to the wall as an extension of a cornice mould.[2]
