Make your Yeti do double duty on the boat or dock with the Yeti Cooler Seat Cushion. The seat cushion has at least two inches of dense foam (three inches for the Tundra 125, 160, and 250 cushions) and is made of tough, white, UV marine vinyl stitched with Gore Tenara Sewing Thread. To install, screw the included studs into the cooler lid and snap the cushion in place. Cushion is available for all Yeti Tundra Hard Cooler models and all hardware is stainless steel. Cushion is water-repellant and engineered with an ultra-tough material inspired by jet ski and tractor seats, which basically means it’s great at repelling water and easy to wipe down.
