Here's one of me in the car so you can see how high I sit.
It doesn't feel too high, in fact it is just right for putting your arm on the side! Any lower and you wouldn't be able to rest your arm, so I am pleased with the way the seats turned out. They are very comfortable, and I remember that I don't have lowered floorpans in. If I slouch I can go lower, but why would I want to slouch when I am driving a Sammio Spyder?
Overall, a great choice and although the seats are not adjustable, they are just right and have a comfortable position, and to be honest, when you start to get the interior in the spyder, the cockpit starts to get very snug!
