Comfort seats with memory function are part of the seat concept that was originally developed for the Audi A8, and are currently available in other Audi vehicles. An upper backrest adjustment function is integrated into the backrest, making it possible to angle the top third of the backrest to provide better support for the shoulders. Rear knee room has also been further increased thanks to the seats' slim design. The seats also have a lumbar support that can be adjusted in four directions, a memory function for both front seats, electrically adjustable head restraints and electric belt height adjusters. Like the standard seats that can be adjusted in eight directions, the comfort seats also have electric fore/aft, height, inclination and backrest angle adjustment. All front seat versions in the Audi A8 also have crash-activated head restraints to prevent injuries to the neck. Switches for adjusting the seats are located in an easily accessible position on the side trim and can be operated intuitively.
