3rd row seats are big enough and comfortable enough for an adult. 2nd row seats are the best captain chairs I have ever sat in in a car. Glass roof gives additional room appearance. see full Mercedes-Benz R-Class review |

The STANDARD leather seating surfaces on the 2006 front seats - way better feel than artico leather. The adjustment range to get things just right and the head rest. Very cozy. see full Mercedes-Benz R-Class review |
