Folding beds provide a convenient way to create temporary sleeping arrangements without having to worry about space. Folding beds for adults are generally made of a lightweight metal frame that is easy to fold and store away. Some frames have wheels, making it easier to move them around. The mattress can either be cradled by a spring mesh surface or be placed on wooden slats.
