Heather Moffat Seat Saver
I used one on my Penwood saddle (didn't need it on the Barnsby) and it was brill :D
Don't know what set me off thinking about it, and now I don't know where it is(!), but I do remember that it saved my achey bum :D
Quite interested in the sticky type seat saver thingies, but my saddle has a sueded seat so don't know if that's a good combination.
Of course my Barnsby might not fit my next horse (think it will be too narrow and too big for Titch - will have to work out how to manage my long thighs and a comparatively short-backed ponio).
Anyhoo, just thought I'd mention it :D
