Heated seats - can they be retrofitted on non-leather seats?

[Greeners]

I never really liked them until I started suffering with a bad back

Is that from all the wheel changing or from the obsessive cleaning?

Neither, truth be told it was changing the roof lining on my MK2 a few years back!

That's absolutely fine mate, thinking about it, I probably wouldn't use them much, i've never had a car with them, so it's kind of a novelty thought, but that said, in the winter the heater is warm quick enough!

I think I am doing a few extras that the car might have had.. (Cruise control booked in for my cam belt/DSG server and im now looking @ MFSW & 18" Monza upgrades!) but the heated seats will officially be left out! :)
