Several people have asked about this seat.....Here is a pic of the home made air seat..made from a lawn mower inner tube, about 80% deflated, I duct taped it into a v shape and covered it...you cant see it when you are riding, and you just throw it into your bag when get off....It contours your butt nicely, and is a lot softer than the spring seat I tried out..or memory foam..you are riding on air..
