Gonerama, the isabelle did not work for me, but my friends daughter loves hers. I think it is a personal thing really, like anything. They seem to suit a slim build and flexable rider, so as I dont tick both those boxes I got something else that works better for me...now I have a near new isabelle not being used. If you have a tendency to slouch or lean back, the isabelle would definately correct that, but if you have back issues I would try something else. Very comfortable seat though, even for long rides...no pressure points at all.
