UPHOLSTERED in either leather or fabric, depending on the specification, the C-class seats aim to combine modern design with improved ergonomics and operation. Standard front seat adjustment across the range comprises electric height and backrest angle and manual fore/aft and seat cushion angle. A complete power adjustment package with memory for all functions of the front seats is available as an option. Engineers have honed in on lateral and thigh support of seat cushions, while a comfortable seat climate is ensured by ventilated holes in the foam cushion. There is no lumbar adjustment.
