ABSTRACT:
A transportable and foldable articulated bed with a non-positively driven articulated mattress platform that reduces the risk of injury and permits the bed to be folded for transport without disconnecting platform drive systems. The mattress platform is articulated on a foldable frame consisting of a head section hinged to a foot section. A pair of retractable caster assemblies can be swiveled 270 degrees from a storage position mounted on the head frame section and connected to the foot frame section with both sections aligned to a position where it can also be connected to both sections when the bed is folded so it can be rolled about.
