I was reading recently of a teacher who uses exercise balls for her elementary school students. That made me wonder about the possibility of using it as a work chair. I don't own one, but tested it out (for a short period) this past weekend at the pool/gym. I'm wondering, does anyone do this and how to you find it? Do you have a wall behind you or just the ball? I'm curious... Thanks, Kevin
