The seats in the Mercedes-Benz C-Class make a valuable contribution to comfort on long journeys. As an optional extra, climatised seats are now available for the driver and front passenger. They ensure a high degree of thermal seating comfort thanks to small electric fans in the upholstery of the cushion and in the backrest which draw in ambient air, then push it through the perforated seat cover up to the surface. As well as this ventilation feature the climatised seats also include seat heating.

The height and backrest angle of the front seats can be electrically adjusted. Even more ease of operation is available as an optional extra in the form of fully electric adjustment of the driver's and front-passenger seat. In conjunction with the Memory package three settings can be stored.

The multicontour seat (available as an optional extra) has separately controllable air chambers under the upholstery material. They make it possible for the occupants to adapt the shape of the seat precisely to suit their anatomy or their preferences. This is all thanks to inflatable air chambers underneath the upholstery material which enable the contouring of the side bolsters to be individually set. Another attribute is the function for pneumatically adjusting the seat cushion length. At the push of a button the seat cushion length can be extended, allowing occupants to relax their legs and ensuring good blood circulation.
