put one on my 226 last year. seaspension seat pedestal. H can make it with the flat side like the original. wife says it take the edge off the slapping, which bothered her back. had to loose most of the space in the drawer underneath and with the swivel added about 1-2" in height.
just told them what i was looking for. they emailed me a picture. fits good, but would have made them about 1" shorter in width to fit inside the armrest. took a pic yesterday. could measure them next time i go down, probably this week end.
i have a 2000 226 and had these made by https://www.affordableboatcushions.com/. they look and work fine, opted for no gw label. just wanted real cushions where i had only bolsters.
Just Checking in on how your seat is performing for you. I put one in for my wife and she says its alot better on the initial shock, but have not been out alot yet.
just put these in this winter. same spot as hookup1 did on my seafarer. working out great. just cut off battery clamps and put to plug.
