I'm interested to learn if other have the same negative opinion on the MB Sport seats? In my case the seats of my 2011 E250 CDI AMG Sport. The following comments relate to my longest regular trip since car purchase two weeks ago of 14 miles. The seat back lugs dig into my ribs at the kidney areas and because of this prevent my back and spine getting full support. In other words I just can't sit far back enough to avoid excessive pressure from these side lugs. I'm 5'10", 36" waist, 38" chest and weigh 74kg. What spec. must my body have to be comfortable in these seats?
