Tempress protective boat seat covers are a great way to protect your investment on an already existing Tempress Seat or a new Tempress Seat. We have also created enough stretch with the design to be considered a universal seat cover. We have (3) sizes to choose from small fold-down, large fold-down, and our XL non-folding helm to best meet your needs. Each cover is made from fade and water resistant polyester and has an adjustable cord to create an optimal fit.
