Lancairites,
I have a whole set of Lancair 320/360 seat cushions that are upholstered and are for sale. Included are 2 seat backs, 2 bottoms, and 1 bottom booster and 1 back booster for kids or short people. These are upholstered nicely in grey cloth upholstery material and are in used but very decent condition. They have zippers and can be washed. The holes in the back are obviously for the control sticks.
They are NOT Oregon Aero cushions but are very comfortable. I upgraded to Oregon Aero and spent $1700 doing it - which was probably stupid, but hey - you only live once.
So for less than 1/3 of that price, you can have yourself a decent set of seats. This are custom built for the Lancair 320/360 but may work on the 235's I'm not sure.
So, the first $500 takes the whole set plus $25
shipping. If I don't sell it here, I'll stick it on ebay or take them to Sun N Fun's Aeromart so if you're interested in these, here's a few pictures:
