I am in the same boat, my cabin condition is quite good except for the drivers seat (Sport, Matrix cloth), it annoys and makes me sad and dearly would love to correct. Like you on the side nearest the door bolster cloth wrinkling, bolster somewhat flat and the seam on the backrest is about to burst.
An idea I have raised before you and others may care to pursue. There must be lots of LHD passenger seats, our drivers side of course, that are going to the incinerator/landfill or available on the used market. I expect generally speaking these will be in excellent condition only rarely having been sat on. I regularly trawl EU Ebays directly, the German Ebay is fruitful, the magic word is 'sitz' with refinements. I cannot see any differences between EU and UK seats.

The drawback is shipping, often no shipping detail to UK which I guess means 'contact seller' but when quoted is about €25. Okay not cheap but overall I would willingly pay up to £150 for a good condition sports seat in Matrix cloth to rectify my sadness.
Alas I have never seen Matrix but have seen several of our designs, eg. Satellite which may interest others. I am beginning to think Matrix cloth was not available in the EU and UK specific, anyone know? I will post on the German A2 club site and ask if nobody knows here.
