People have been looking for seat covers made for a C8 but none are available at this early stage or certainly I've been unable to find any yet. That will no doubt change. I don't know if other seat covers will work (ie. for a C7?) so we'll have to wait for someone's feedback on that. Years ago one of my best friends who had worked continuously for GM since graduating from University (20+ years and now sadly deceased from cancer), told me NOT to spend any money on protecting the seat surfaces, since the factory puts "scotchguard" or the equivalent on the interior surfaces already. I've always followed that advice. However with seats that have high side bolsters, I've noticed a definite wear pattern on their edge closest to the door, over time from entering/exiting, which would be avoided by seat covers or perhaps (?) repeat applications of "scotchguard" on that area.
