I tend to sit with the back quite upright as well.

I notice I don't have these issues in the Range Rover which has a more chair like seat.
Someone (hopefully they are still reading here and will respond) posted that this is what their doctor told them. You want to almost feel like you are going to slide off the front of the seat. Makes sense, when you think about it. By sitting low, keeping the front of your legs up to give your knees some bend, and by sitting upright, you are extending your lower back much more than you would be if your legs were flat. Plus, you're putting extra pressure on your legs just above your knees, which screws up circulation and pinches your sciatic nerve.
The only downside to this, for me, is that I am looking more out of the top of the windshield than I'd like. But that's normal for me. In my MDX, I'm looking through the tint band. It's annoying enough that I contemplated having the windshield in that car replaced with one without a tint band.
