Everytime I drive I end up having a tight lower back. So I did a search and found that a lot of people are experiencing leg pain in their G35 sedans, but not back pain. Anyone else having any lower back stiffness. I know that I don't have the best posture, but I don't have this problem with any other cars I drive. GF

 

hmm i don't have any problems....maybe it's the seat height problem? i don't know

 

Try moving your seat back forward a little. I don't get back pain, but i found that when the seat back was too far back (you know.....the "chillin" look) I would work my lower back muscles quite a bit.

 

The G35 coupe's seats are the most comfortable seats I've ever experienced in a car.
I used to get back pains all the time, especially on long road trips with my old car, but I could drive forever in the G.

My own experience is that I get back pain unless I have the lumbar support cranked to max.

 

I have a pretty bad back... (herniated 2 discs TWICE, and had surgery once)

That said, the G35 Coupe seats have been super comfortable for me. And I have been on a couple extended road trips... Do you by chance keep your wallet in your rear pocket?

And posture actually is very important. When I had surgery, one of my discs had calcification on it, that the surgeon determined was caused by years of poor posture. (I slouch in my desk at work... Well, used to...)

 

Mmmmmmmmm Vicodine!!!!!!! :d
