OREGON AERO
I made my own seats and flew in them for the first 2 years. They were fine, I was 30, tough and didn't know any better. I just put in an Oregon Aero Seat. If somebody were to take my cushions, I would go back and buy some more, they are worth every penny. Those folks know their stuff. $350-400 per seat for the foam, RV 7, roughly double it if you want them to cover it. Oregon Aero is in the middle of upgrading their website, give them a call. 503-543-7399
