Many years ago I lived with my husband in a very small apartment, and we wanted the very small bedroom for an office. So, we just slept on a hide a bed ( fold out couch). It was not difficult at all, the bottom sheet stays on the mattress, so you just scoop off the duvet and pillows, all in one, put the pillows on top of the duvet, roll it up, put it in the closet, fold the mattress frame back into the couch, put the cushions back on the couch. Takes less time than making a conventional bed. Very quick and easy. It is my understanding that the Japanese traditionally had bedding that was rolled up and put away every day so that the space was used for other things.
