I too have been thinking about aftermarket seats, the Pole Positions were at the top of the list, until a couple of weeks ago. They are starting to find some are cracking near the front mounting location, you could imagine the consequences of an accident if the seat sheared.

I also wear cargo pants to keep wallet / cell phone up front in the thigh pockets, it helps a lot. If you've experienced severe back pain it's a horrible way to go through the day, it's also why I purchased a SUV for a daily driver, big difference getting in and out.
