I knew from the moment I sat in the x5 it was not as comfortable as my a4. The x5 rear seats are hard and have no type of cushion and my a4 backseat was so comfortable I use to make my wife drive me while I sat in the back like a chauffeur and cuz we had a newborn. My In laws have a base model mdx and a fx35 and the x5 seats don't even compare. Even my old 92 integra leather seats were more comfortable
