The (optional) sport seats for the C5s are marginally better than the base/Z06 seats...I find them comfortable on long road trips, but they too, suck for holding you in place during more spirited driving. And yeah, the stock leather material on all of them is crap and quite thin and fragile.
Never had the rocking seat or electric probs with them though. 'Course I don't use the memory or easy exit features either. I'm the only driver of it, so other than for cleaning, the seats don't ever move.
