Hello, I have a listing for a boston whaler seat cushion for the 13’ model up to 1999. This cushion has a cover made from Sunbrella fabric in red. I can make it in all other colors as well. The foam in the cushion is a luxury open cell foam and the bottom has a mesh fabric to allow drying if the cushion gets wet. This cushion has snaps in the flaps on the sides. I can adjust the mounting methods if you desire something different. Any questions please ask.

Thanks john
