W204 facelift Artico Driver seat cover spit

[Badboysun]

My driver's Artico leather perforated seat cushion has split along the seam, colour 9D88, how easy is it to replace my self, I've had a quote of £350 from the main dealers, on top of the price of the cover, my seat cushions are not heated, nor memory. I thought it would be a simple swap- four bolts and a few connectors released.
Is it possible to replace with real leather ones? keeping the same colour code in the process, if someone here provided an alternate part number for leather ones as the dealer couldn't advise on a leather part number.
