Quick Interior Question

Looking at changin my interior, I have a facelift MK3 Hatch

I am looking for Variable heated half leather seats.

Do saloon or estate interior fit a hatch ??

Are all front seats the same and just the rear different fittings ???

Also are pre-facelift seats a straight swap into a facelift car

Many thanks

couldnt find any post prior to this usin the search :-(
