definitely a manufacturing defect.
I might've exaggerated a bit but it could be excessive reach-around to the backseat to move stuff or propping yourself up or fixing your slouch by digging in your elbows to the side boosters. That will apply pressure to the entire side bolsters. I'm getting a little sag similar to this but its hardly noticeable. Of course there's so many different possibilities but I wouldn't automatically jump straight to a manufacturers' defect.
