Key features
- At least 2 inches of dense foam; 3 inches for Tundra 125, 160 and 250 cushions
- UV-resistant marine vinyl cover
- Stitched with GORE TENARA sewing thread
- Stainless steel hardware and included studs

Sitting comfortably on the dock
A cooler cushion adds padding to a hard seat, which helps on long waits at the dock or on a boat. The vinyl top sheds water, so a quick wipe after use keeps it looking good. Check the foam for compression over time, since flattened padding gives less cushioning and can make the seat uncomfortable. Choose a cushion whose foam thickness suits how long you plan to sit.
Keep the stud connections firm by checking them before each outing, because loose studs can let the cushion shift on the lid. Store the cushion in a cool, shaded place when it is not in use, and avoid leaving it in direct sun for long periods, which can dry and crack vinyl. Rinse off salt water and let it dry fully before storing.
