TJ Wrangler seats

I have a question for those of you in the know. I blogged about a salvage TJ Unlimited a while ago. This TJ came with OE seating surfaces that look like leather.

I understand there was a TJ trim package that included these seats some time between 2003-2006. My question is, are the seating surfaces leather, or vinyl that looks like it?

Somebody out there knows the answer.

Thanks.
