For anyone else that finds this thread in the future.
It's a 4 step process:
1 - the leather on the back of the seat wraps up underneath the back of the seat and is attached by two bungie chords to two hooks under the seat. Just feel under there and stretch each one forward towards the front of the seat and it will unhook and swing down.
2 - there is a footwell light that has a wire harness attached to a small hole in that flap. You need to disconnect that light from the bracket to be able to fold back the leather flap
3 - fold up the flap and there are two screws holding the bottom of the seatback to the seat. Remove those.
4 - You need to lift the whole seatback upward. the clips are thick flat plastic at the top of the seatback - picture an lowercase f. You need to pull it back towards the back of the vehicle while also pulling upward in order to unhook it from the bracket.
Putting it back on is easier - you just line up the hooks with their slots on the top of the seat and push it down until it clicks. Replace the screws, reattach the footwell light to the leather flap (a little awkward), then stretch the bungies one at a time until they hook on the hooks underneath the seat.
Hope this helps someone!
