What "seat housing" are you referring to? Do you mean plastic trim around the seat? Metal frame under the cushion? Stitching?
As for others complaining about seat wear - most do not use the easy-out memory, then complain the leather is too thin, or inferior quality. Funny how this only happens on the Corvette (ooops, let me check the XLR Forum) ... and not other GM vehicles. That, in and of its own, shows it is a user error in all but the most remote instances.
Leather does not wear through ... but rather, even if left untreated, it will crack with age. Leather does not wear through on its own. The cow never had an issue with bones popping through, so the wearing issues are indeed from abrasions of some sort or another.
