The R-Class offers generous amounts of headroom and legroom as well as full-sized, luxury forward facing seats throughout. The front driver and front passenger seats are also fully electrically adjustable, except for on the R 280 CDI SE, R 320 CDI SE and R 320 L CDI SE models, where partial electric adjustment (backrest and height) is fitted. All models feature armrests as standard.

For all Sport models and the R 500 L SE, four-way electric lumbar support is equipped for the driver’s seat. The R 280 CDI SE and R 320 L CDI SE have manually adjustable lumbar support for the driver’s seat. Electric lumbar support is available when Artico man-made leather or leather upholstery is specified.

For added convenience when sharing the driving, the optional Memory Package remembers the settings of the front seats, the exterior mirrors and the steering column, and includes four-way electric lumbar support for the front passenger seat.
