Interior re-trimming - Seats and door cards for a 306

[lowpugV2]

Hi All. My 2001 306 XSi is going very well so I'd like to refresh the interior. It's actually pretty good but the drivers seat has some seams starting to split and I also have the classic door card fabric sag.

My seats are the airbag type though - can these be retrimmed? Is there a reputable Sydney shop that would do this?

Thanks!
