Re: Cockpit Cushion Foam
I vote for closed call foam, period. Any drawbacks are pretty much still a win because it absorbs zero water.
In foam rubbers, they are all measured by "durometer". If the seller can't tell you a rating for the foam, they're just clerks, find a better seller. A "20" foam will be very soft and compressible, a 100 foam would be an unyielding mattress. Somewhere like 40-60-70 is probably what you'll be recommended to get, IIRC, depending on the thickness of the foam. And of course, the closed cell tends to compress less and be stiffer to start with.
Closed cell can also literally be a lifesaver, if you need to throw it to a MOB. ("Honey, not the cushions, he's not THAT good a friend.")
