Well, these likely are not what your looking for but I ordered custom sheepskin covers from Sheepskin Seat Covers for Cars,Trucks RV's | US Sheepskin. Pricey but I have used them before and they are of very high quality, fit well with their custom orders and are so luxurious. I don't care for the feel of leather against my skin and like you I found so few other alternatives that were available or of any known quality. I even checked locally with upholstery shops that might be able to fashion something more in line with the nice lines these seats have. No love.
