There is no lumbar support at all in the seats in the '94 wagon. So bad in fact that it caused Sciatic problems for me after one year of driving. I've bought lumbar suppport thingys and they help a little but my leg still goes numb and then throbs on long drives. Very uncomfortable. Recently I had the wagon in for repairs (duh) and I was given some POS Chevy Trailblazer as a loaner but what I noticed was no back pain at all. It had a lumbar adjustable support 'wheel' and was very comfortable.

I need help solving this problem. I don't want to give up the wagon but the seats are terrible and are causing me much pain. What are my options? I can't believe that the trailblazer was more comfortable than the wagon!
