Seat SIP Super Corsa Vespa PX


can anyone help me? I would like to buy a SIP Super Corsa seat (copy of the Giuliari- black blue) for my PX, but I know a guy that has one similar (not the SIP one) and it is like if you are sitting on a stone. do you know if the SIP one is confortable or it is hard as well?

Many thanks


I had an SIP one a couple of years back, rock hard…
