A wheeled carrier (10) which includes a substantially planar back frame (20) and a substantially planar base frame (34) which is rotationally coupled to the back frame (20). The base frame (34) extends in a substantially horizontal plane and the back frame (20) may be rotationally displaced from a substantially vertical plane to a substantially horizontal plane. The wheeled carrier (10) further includes a plurality of wheel members (54, 54', 56, 56') which are rotatably coupled to the base frame (34) for rolling the wheeled carrier (10) on a base surface (12). A containment mechanism (62) is provided and is releasably coupled to the back frame (20) and the base frame (34) for preventing a user from falling external to the wheeled carrier (10). The containment mechanism (62) is vertically adjustable with respect to the base frame (34) and the back frame (20) and is also removable from the back and base frames (20 and 34) in order that the back frame (20) may be rotated to a substantially horizontal plane in order to permit a user to lie on the wheeled carrier (10).
