The lumbar support in the passenger seat is too thick. It always bothers me when I sit there. On the forum I read the leather on the seat is glued and is easy to get loose.

At both sides I loosened the leather over a significant bit, so you can get to the foam.

With a palet knife I could remove the foam from the back of the seat. You don't see a lot from the leather. There is still a slight bump in there.

After removing the foam, glue the leather back.
