subaru seats - Pain

I was wondering if any on you knew what the subaru seats are made of, as my mom had a 2000 subaru outback, and now owns a 2005, and all the times i have ever driven them for more than half an hour at a time, they have led up to screaming lower back pain, to the point where it hurts to walk around after i get out of the car
i have never had any sort of problem with saab seats, malibu seats, dodge truck seats, and all the other cars i have driven

if any body knows what they are made of, and if they have switched them for the 08 models like on the impreza 2.5i that would be great as i am looking to buy one

Check to see if the lumbar support is at minimum or maximum. If it's at max, your back might not be liking it.

i have done all of that, but it still bothers me, any idea of what they make the seat out of, as i am referring, to the frame, cushioning material and cover

Boring yellow foam inside. Same I've seen on any other Japanese cars...

so why does it give me pain when other cars like that, the suzuki, and honda as such, have neglected to give me pain in that area?
