An improvement in the form of an attachment to a conventional shopping cart comprises a platform to which is secured a pivot bar, the length of which is proportioned to extend beyond the ends of the platform in a position to be pivotally connected to transversely spaced frame members of the cart. The platform is secured to the top portion a frame in the form of transversely spaced, identically formed, metal loops, having reinforcing or bracing bars extending therebetween. The attachment, in one extreme position to which it is pivotally swingable, becomes wholly recessed within the space beneath the basket of the shopping cart, while in another extreme position, the platform is disposed horizontally and is extended rearwardly from the shopping cart, thus to provide a step on which one can stand to reach articles on higher shelves. When one stands upon the step, the frame secured to the underside of the platform has portions that are disposed as treads engageable against the floor surface, and binding frictionally against the surface in a manner to assure not only a stable step attachment for the user, but also to provide a brake that will prevent movement of the cart while one is using the step attachment.
