I love my Boxster, but it's murder on my back. My seats have no lumbar support, so I've tried a couple things to get better support - a small pillow and an inflateable bag. I tried the bag both tucked behind the seat facing and in front of the seat - in both cases it doesn't seem to get low enough. The pillow doesn't work for more than a couple of hours. Long drives are a pain, literally, and it progresses from my back to a bad pain in my leg. I'm 53, so I'm sure age has a lot to do with it.
