Switching seat fabrics/trims

[benough]

Hi there.

I've had it done on my MK2 Golf GTI, the foam base of the seat switch out for replacement one onto the frame, but does anyone know if it can be done on MK5 seats?

After 7 years my drivers seat has worn thin on the bolster and torn. Also the inner tartan trim is losing colour. I figure I could swap the trims, as the passenger side is mint!

Thanks
