My car has already 10 1/2 years on the hump and this of course also does not pass the seats without a trace. Optically, they are still in a 1A condition, but with the driver’s seat the back is already a bit shaky and therefore it also snorts something. The Lordose support also does not come out so nicely (in contrast to the passenger seat, which is still really tight and stable). Especially the Lordose support I need for my vortex acid and when my wife was driving and I was just a passenger, I noticed that the difference between the two seats is enormous in terms of overall stability. It is about electric seats with memory fct. on the driver’s side. Now to my question, can the seats of drivers – & co-drivers be exchanged regardless of the underbody that contains the levers/switches for seat adjustment???? Thank you in advance.
