Described is a collapsible cart that provides substantial stability when operated. A pair of enlarged wheels allow an operator to lift one end of the cart to traverse rough surfaces as needed. Enlarged wheels are mounted outside an overhead profile of the collapsible cart thereby providing lateral and other stability not previously possible. A first shelf, tray, bucket or working surface may be collapsed to contact or mate with a second such shelf to create an easily transportable or storable collapsed structure. A telescoping handle allows a collapsed cart to serve as a hand dolly.
