A walking carriage or ambulatory aid having a frame that supports front wheels and a collapsing rear support for rear wheels. A seat supported to the push rods of the frame has a grip at its rear. The seat is connected with the support for the rear wheels so that when the rear of the seat is lifted, the rear wheels are pivoted toward the front wheels to collapse the carriage. A tray is pivoted to the frame between a first pivot position above the seat and a second position below the seat and over an article carrier supported on the frame.
