For additional support, a unitary bar extends along the open perimeter of the basket and along a portion of the underside of the bottom panel adjacent to the open rear edge. The basket is hingedly attached to the metal chassis to permit the baskets rotation from a horizontal to a vertical position to facilitate cleaning and close nesting with other carts. The metal chassis is of lightweight tubular construction and rests on a plurality of swivel casters. To facilitate use of the cart by a person confined to a wheelchair to portable walker, the rear vertical members of the cart chassis are provided with V-shaped guides and fastening chains to permit attachment to the front vertical members of the wheelchair or walker.
