I don't know if this advice will work perfectly for a re-cover, but I would think it should. In the oem manufacturing environment they put a thin plastic bag around the foam bun & while it's in position on the seat frame pull a vacuum on it. This sucks the air out of the foam bun to make it smaller for the leather seat cover to be quickly slid on. Once the leather is slid on, the vacuum is released and the bag pulled (ripped) out. They use the same vacuum trick with the headrest bun. Sometimes you find some remnants of the bag they used under the edges and corners where it's really tight. Then they stretch the seatcover and hog ring it. I have one of the pneumatic hog ring guns they use for when I someday do mine. I should rent it out or something. But it might take different rings that fit it's magazine.
Thought this might help save you guys some time. They obviously can't wrestle with a seat for very long on the production line. Maybe some of the principles can still be used by the do-it-yourselfer to save time.
