Most are cloth, except for the leather ones, you can get new covers through the dealer. The drivers seat does tend to wear along the backrest by the door armrest. If you go with an aftermarket seat cover, make sure it has the opening for the airbag on the outside of the seat backrest
There are a lot listed in the EPC. If you would like the exact patern/color you have you could PM me your VIN and it will be so much easier to get the part number for you. I tried mine, it has gray leather. Sadly I couldn't pull it up on the site.
