A folding cart can be unfolded from a flat, collapsed position to an open position. The cart has opposing front and back side walls which have ledges on their opposing faces, and opposing foldable walls hingedly secured to the front and back side walls. A bottom shelf is positioned on the ledges, and a top lid is positioned on top of the walls to form an inner storage cavity. The cart has wheel assemblies which are pivotally mounted to opposite sides of the back wall, and adjustable legs for firmly fixing or securing the cart to the ground. An umbrella pole passes through openings in the lid and the bottom shelf.
