Moving the rear seat to the commercial ("N1") position is very easy and takes about 15-20 minutes, and is completely reversible if you don't like it.
From the cargo area, remove the 4 Torx bolts holding the black trim piece on at the bottom of the rear seat, then remove the 8 bolts holding the rear seat base. Move to the rear side doors, flip the bottom cushions up/forward and remove the 2 bolts securing the seat base to the driveshaft tunnel (in the middle of the vehicle), then remove the black side trim pieces (vertically, near the doors), these have a phillips head screw that is quarter-turn, and then just pulls off; this will expose the last 2 Torx bolts per side. At the same time as this, remove the Torx bolts in the forward holes (it will make sense when you look at them), the "forward" holes for the rear seat are only exposed after you slide the seat forward.
This will move the seat about 90mm forward and make the seat about 10° more upright
