Sea Dek products, just as these coaming pads are, are manufactured from the highest quality EVA foam, which is non absorbent and extremely durable. While other imitators exist, no company can match the lifetime and integrity of Sea Dek. Using Sea Dek Coaming Bolster pads on your boat can significantly improve your comfort while fishing or riding. These leaning pads are ideally mounted to high traffic areas around your boat where you do a good amount of fishing, which is ideal everywhere! Simply mount using the 3M backing, and not your legs can take it easy when your leaning into a big grouper or kingfish! These Bolster Pads are also great to sit up against when your just cruising.
