I find the seats to be typical european car firm, but typical mercedes flat--especially the seat bottoms. I like to have the seat angled a bit more than I can currently achieve with the crossfire so that my legs have a bit of support. I don't feel that the side bolsters are anywhere near aggressive on the car. Drive a car with real sports seats and you will notice the difference. Sit in a crossfire and find a mercedes C63 for example---worlds apart with reference to bolster aggressiveness (among other things!).
