boytronic - I find them extremely comfortable. I had them in my Stradale (no choice there) so when it came time to order my F430 they were almost a must have for me. I've even had passengers comment about how comfortable & supporting they are. They actually feel better to me than the adaptive sport seats in my Turbo Cab. But everyone is different, what one person sees as un-comfortable, another can feel the opposite.
There's also different sizes for these Ferrari racing seats so you also have to make sure you're not a 220lb guy sitting in a sized Small racing seat. Many people over-look this because the only time it ever really comes up is at time of ordering.
