I also get this with my back adjuster wanting to be in between clicks. :/I took 2 years of fiddling every day to get comfortable. Eventually found it best with the height adjuster at its lowest i.e on the floor. I hate the back adjuster though, always seem to want it between the clicks!
I had the same problem, very uncomfortable seat. See my post on page 2, #23 about the Obusforme:

Am quite tempted by this BackFriend product. Has anyone tried it?
