how and where to repair RECAROS 197 cup

I picked up a second hand white cup with all the trimmings and need to know how and where to get a small (2inch) tear at the side of seat where you brush past it as you get in and out....any help would be great...cheers
 
Is the car under warranty? if so, nip to your local dealer and they should sort it.

Mine are just starting to wear :worried:
