Abstract
A combination transport device and work surface has a collapsible support member and base member. In the collapsed position, the support member and base member are close to a stem of the device to define a transport surface. The transport surface can be easily moved via a handle and wheels. In the extended position, the support member and the base member extend transversely from the stem to define a work surface and a support base respectively.
