A wagon features a plastic body, bolster and handle. The bolster is pivotally mounted to the bottom of the wagon body and receives an axle to which the front wheels are attached. The rear wheels are mounted to the bottom under the back portion of the wagon. The bolster features a number of spaced prongs, each of which includes an aperture. Some of the apertures are surrounded by channels including arcuate surfaces. The wagon handle features a number of spaced fingers, each of which includes an aperture. Some of the apertures are surrounded by bosses featuring circumferential walls. The fingers of the handle are placed between the prongs of the bolster with the bosses positioned within the channels so that the boss circumferential walls engage the channel arcuate surfaces as the wagon is pulled by its handle. A hinge pin is received through the handle and bolster apertures so that the handle and bolster are joined in a hinged fashion.
