I have issues with the seats, too, Namely that the back doesn't breathe, at all and you end up with a sweaty back in the summer as there is no air flow. The seat creates a hot pocket. Maybe try to locate some SLK 320 seats, which look like they have the exact same carriage as the Crossfire. Maybe you can find some SL seats which are bound to be even MORE comfortable. I'd have to get the reupholstered to match the cedar interior of my xfire
