Not quite sure what you mean.

Are you saying that the seats need to be longer to reach under your legs more?

I'm not quite understanding how you are sitting. I'm 6' and keep the back of the seat fairly straight up for posture and find the seats reach comfortably enough.

I understand it's uncomfortable for you, but just wondering if has more to do with your posture and how you're sitting. If your don't have good posture while sitting, now is a good time to start until you find a better solution. Of course, it could just be we have different trunks and kicks.

Perhaps some type of seat cushion would work. I find a soft pillow behind my back works great on long drives, but that probably wouldn't help you here.
