Have you tried playing with the lumbar support and seat bottom angle a bit? I typically need a little lumbar support in most cars, but I have noticed that with this seat I need more than I think I usually do. I have noticed the lumbar deflating so every couple days when my back starts to hurt a little I pump it up again and my back says "Aaahhhh...." LOL.
Also, bringing the front of the seat bottom up higher has helped in my case.
I don't think I have ever attributed a noticable increase in back pain to these seats, but I was rearended a few months ago and while the car was in the body shop I had a 2013 Jetta rental for a month. Those two things together and my back was not happy. After I got the LGT back I figured out that an increase in the lumbar helped the stiffness and tweaks go away.
