boat seats for rough water

[rmblam]

I just got back from a trip up to Leech Lake in Minnesota and I had a chance to think about something. I met a guy, with a boat like mine, who had these seats made for handling rough water. The kind that help keep your spine intact.... I've abused my wife a few times with the boat and jolted my own spine on many occasions. My problem is that I can't remember who made these seats and support pedestal. It is not the Glyde-ride. They have an adjustment handle(s) for height..etc and a big turn nob for impact tension. Has anyone else come across any air ride or support seats for rough water handling? Short of tracking the guy down I was hoping someone else could help...? Thanks if anyone can. I really liked these seats and internet searches have yielded nothing.
