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) or ARTICO man-made leather (standard in the ML 500). 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.
