I am posing this as a question because everyone is different. I thought I share this so readers might experiment in similar fashion or may comment how they dealt with an uncomfortable situation.
At first I found the seat in my 05 Vibe to be rather uncomfortable. It made me slouch and that caused pain in the lumbar section. Doing a little research I found this video:

Honestly, I hate the idea of putting pillows, foam pieces, cloth and such junk around me in the car. But I did learn something form this video.
1. I raised the seat height significantly. This had the same effect as putting a foam wedge on the seat.
2. I reclined the seat back a little. One and two together created a little bit of lumbar support. In fact it is enough that I can imagine to drive 1 hour or so. I still need a little bit more lumbar support.
3. I moved the seat a little bit forward. This compensated for the added amount of recline.
However, I still have to move my shoulders off the seat back when the hands are on top of the steering wheel. If I move the seat forward it will make my leg room too tight. At this point I wish for a telescoping steering wheel or adjustable pedals.
Here is the question: did you find a position that is comfortable for many hours of driving?
