They are quite comfortable - im 6 feet 2in and i still fit, i did feel as if i was sitting too high up - but after a few days i have got used to it. They do hold you in the seat very well. If i could change anything on the seats it would be for them to be hight adjustable - just so i can see how different it feel to be lower, and maybe a lumber support, but i don't feel like the circulation or my back is hurting when sitting in them for long periods of time
