hey
that is a problem i do not have. i have one of those rubber seats.....not too comfortable....but unbreakable.
i try to do drop offs as often as i can (i just started so i fall a lot while droping off stuff) and i've leant my uni to quite a few people who wanted to try it....but still it looks brand new (except for a white stain that all af a sudden appeared.....look like white out....could be a prank for a friend.)
anyway....if you really want a tough seat...get a rubber one
or maybe one with a bumper.......i never tried those, but i imagine it protects the seat.
