Jim,

I have Kirkey low-backs in my car (they're 17") and you're welcome to try them out when we get together once the weather turns nice. I'm 6' and 220 lbs or so and still have room in them, but I went with very thin padding when my local upholsterer covered them - just a bare minimum of high-density foam and some medium-density to give them shape.

If you like the look of the old-school leather ones, you'll like how he did my Kirkey's. Also, they have inflatable lumbar support and seat heaters - lots you can do when not ordering off the menu.
