Have you thought about having an upholstery shop recover your old ones? You can have then done to your liking. Could even have the front done so that they all match with a custom look. I plan on doing mine at a latter time.
I actually took the rear seat into the upholstry shop, and they couldn't match the fabric. I would get them all done, but the front seat is very nice, as is the bottom cushion on the rear. The rear seat back is the only thing keeping my interior job from being finished. I should have covered up the interior a little better when being stored!
