The way you sit affects the way you drive, so in the M-Class the focus is on comfort. The seats have been designed with ergonomics in mind. And there are various upholstery options to suit different tastes: an "Aspen" fabric/ARTICO man-made leather combination (standard in the V6 models), leather or nappa leather (standard in the ML 63 AMG). The height, backrest angle and seat cushion angle of the front seats are electrically adjustable. The fore-and-aft position and head restraints are adjusted manually. Sports seats, upholstered in an Alcantara/ARTICO man-made leather combination with contrasting topstitching, and multicontour seats are available as an option for the driver and front seat passenger.
