Abstract: A seatback utility device provides a compact and convenient way to address the need to hold personal articles and concession snacks. An arched protrusion from the seatback extends most of the way across the seatback, and is configured to hold a variety of items brought to a sporting event by a patron. One embodiment may securely retain an appropriately configured concession tray or box. In some embodiments, electronic or fixed, movable advertising displays may be accommodated.
