The Gen 2 seats are very comfortable but I wanted a little bit more lumbar support. I had an inflatable kidney-shaped bladder from a chair that I folded in half and stuck in the map pocket behind the driver's seat. It works great and it has a tube with a rubber ball that I can pump up to get just the right feel. The inflater sits in the cup holder. I usually deflate it upon returning home so that the map pocket doesn't get over stretched. If you don't happen to have one of these, you can find these types of things on Amazon with a bit of searching.
