Beds are big, space-consuming furniture objects by nature. There are transforming or fold-up alternatives but one of the best, simplest and cheapest ways to get the most out of the volume they occupy is by having them serve a second, third or fourth purpose in addition to being a sleeping space.The results are simple, elegant and functional - they are not eye-popping or outrageous as some convertible furniture designs can be. Nonetheless, they would fit well in a number of interior design contexts and make better use of one of the most space-displacing objects in your bedroom.
