Re: Drivers Seat Lumbar Problem
Can't say that I've put a micrometer to it, but ours appears to go up and down more than in and out. It seems to help my back slightly, not hurt it, when it is adjusted near the lowest setting, and I have a trouble-prone back. But a slight upward adjustment from there and it definitely becomes uncomfortable. Yet, I'm pretty tall, and have wondered whether the lumbar might be a problem for some shorter folks who find the lowest setting to be too high.
You might try experimenting some more with it to see whether there is a sweet spot that aids your spine, or at least causes no harm -- small changes might make a considerable difference. Alternatively, you might be able to pull off the seat back and remove the lumbar block or modify it.
