To cover or fill with down feathers; to pad or cushion with soft feathers.
Prefix 'be-' combined with 'down' (Old Norse 'dúnn', the soft feathers). The verb means to add down padding or covering.
Medieval bed-makers took 'bedown' seriously—goose down loses warmth when compressed, so skilled craftspeople had to know exactly how much fluffing each night would require to maintain insulation.
