Thought I would share this with you guys
GM made some seats with a plastic piece sewn across the middle seam of the seat and others they just sewed extra fabric across the middle seam.
On the ones with the plastic piece it breaks in the middle and the stitching pulls the plastic so it overlaps and pushes up in the pucker shape.
Broken plastic piece
Pucker caused by broken plastic
Extra fabric style seat
No pucker
