I was given these cushions three years ago by jptakefive when he got a new set made, and they have served me quite well. So well in fact, that I’m having new set made by the same company that made these (C Cushions Inc.). They’re not as supple as they probably once were, and a couple areas where the vinyl outer surface is coming off, but they still have a few years left in them yet. They’re still waterproof and quite comfortable. They also fit the F36/38 cockpit perfectly.
Let me know if you’re interested. They’re located in Cambridge, MA.
