I did the front leather on the 560 using good leather from a wrecked 420. My task included sewing the heating pads from the original leather to the 420's leather. Most difficult part was all the hand stitching. My job was made easier due to instaling used leather, I imagine trying to stretch new leather would be a royal pain. The upholstery is retained in small channels by means of a cardboard/hardboard slat wrapped in the leather cover.

You may be able to determine if there are any broken spring prior to removal, but note that I wasn't able to. Only after the seats were removed was I able to find the broken spring.

It basically took me three days to do both front seats. Try a search on "heated seats" by me, I think I posted some of the pictures in that thread.
