Ideal for living in small spaces, a Murphy bed is an otherwise normal-sized bed that folds up into an alcove, an armoire, or a closet for storage. The mattress is attached to the bed frame — often with a strap or bolts — and does not use a box spring. It usually folds up at the head of the bed to be concealed by a pair of doors.
Often, you'll find Murphy beds built into studio apartments or other small rooms, and you can also buy wall beds to install in your home. Murphy beds are named for William L. Murphy, who held the first patent on the design in 1916.
