A polyfoam cushion is formed as a triangular right prism 12 inches on a side and 5 inches in height. A thin cover encloses the prism, and defines a zippered pocket in which string fasteners are provided for securing the assembly to a chair. Safety straps encircle the child, and these straps are also stowed in the pocket. The polyfoam is relatively stiff, in order to support a 50 pound child without compressing the polyfoam prism. The use of polyfoam yields a cushion of less than one pound in weight, the child can transport his cushion by holding a handle located on the same side as the pocket.
