Hi guys question for you's

I have the airflo comfort zone rotary boat seat and I was wondering if anyone has this and/ or know someone who does.

My question is if anyone has changed the actual seat to a different one and if so what seat it was. The airflo seat is so bad and I can barely handle and hour of 2.

If anyone has any idea of what I could do as I like the rotary on it.

Other wise do I just build one using a wooden beam like I have seen a lot of people with?

Thanks guys
