piggies, piggies, lots of piggies...
You might try a company call Wolverine Worldwide...the are a huge company that started out making work gloves, and make shoes, etc, and also sell hides for furniture, etc. I was under the impression that the "perf" is the void where hair once was, but I could be wrong. I know that the hides are smaller, as pigs are smaller than cows, but you are not covering a Chesterfield, and car seats are relatively small pieces...I toured their factory near Grand Rapids, MI, but that was when I was in design school, a few decades ago. They were all about quality then, and I think they still are. I took a quick look at their website, and they may be of help; but I'm not sure about retail distribution/etc. Good luck, I hope it works out for you.
