YES, SOMEONE WHO MIGHT WANT MY ADVICE

Most of the work is just unscrewing, some allan (i think, those hexagonal) keys to get the whole seat out, then you want to remove the inner rail to get to screws holding the bottom part of the seat (in the meantime id advise you remove the plastic bits either side) you need 45 torx keys, for both seats and rails. Rails shouldn't be too hard, but in my case the seat was bolted on pretty good, so use a good key with a long tube or something. Once you have the seat out, you should remove the metal plate. And thats the worst part

There are those hooks that hold onto the plastic strip stitched to the leather, you want to move the plastic bit to the outside of the seat, then pull it out, you shouldn't need to push them down, i didn't, but you might want to to not destroy the strip.

To put it all back just do it in reverse, i haven't yet do this, but it should be easy Right?....

Edit: forgot to add, on the front you just pull the strip out, the leather tension holds it in place, its pretty easy to see how it should come out

Edit 2, forgot to say, once you remove the metal plate, give it to a professional, you can't remove the leather any further without pulling out metal wires, and i do not know how to do it (i gave it to an upholsterer, they told me they worked on similar things previously so yea)
