I swapped seat cushion and leather on mine, I seem to remember the moulding of the cushion and the leather pattern being different side to side. I am planning to get an industrial sewing machine though after learning a bit about it, you can take the old covers apart and use them for a template for new ones. Then glue new foam to the old foam and done. When I did the swap I added a bunch of new foam right where your butt sits.
