These Cooler Cushions are made of durable tetron and for comfort, the cushion back has adjustable side straps and, for strength, a wood backing in the seat back. The cooler pocket hangs in front, putting your beverage within easy reach. When closed, drinks stay cold for hours. Pouch capacity is eight 12 oz cans with ice. The mesh covering keeps your legs from sticking to the seat on a hot day and the bench strap under the seat holds the cushion to the bleacher. A pocket for your cell phone, a shoulder strap and handle round out the extensive features.
