Abstract
Abstract A cushion for a sofa or chair or the like, preferably formed of a polyurethane foam pad and a vinyl cover. Buttons are incorporated to provide dimples in the cover. The buttons are the heads of pins which project into the pad and are fastened in place at a separation in the pad. The pad may be slit to provide the separation or may be made in two pieces sandwich style. A filler of lesser width and length than the pad may be positioned within the pad at the separation to provide a crown for the cushion.
