This is the (partial) front of a seat pad removed from one of my kayaks. The material is 1/2" thick, soft, covered with fabric, and good to pad pressure points.
Here is the back:
I have no idea what it’s called or what glue to use. I thought it might be neoprene, but haven’t found any 1/2" thick. EVA foam? Closed cell foam?
Thanks for any help.
