A box-bed

A box-bed (or closed bed, close bed, enclosed bed) is a bed enclosed in furniture that looks like a cupboard, half-opened or not. The form originates in western European late medieval furniture.
The box-bed is closed on all sides by panels of wood. One enters it by removing curtains, opening a door hinge or sliding doors on one or two slides. The bed is placed on short legs to prevent moisture due to a dirt floor.
