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.

Pucker caused by broken plastic
