If you have one fabricated, make sure the cushions can be made secure to the boat: screw, zipper, or tether.
A nice new white cushion floated-in several years ago. I may have posted it here in the "Lost and Found" forum, but I eventually took it to
Wolfeboro Goodhue & Hawkins, hoping the
Cobalt renter/owner and the cushion could be reunited.
