It wasn't too bad. The actual seats themselfs (foams and cloth) are slightly too big for the car so crease slightly in the corners but I can live with that.

The hardest part was getting the locks in the right place so both side sat at the same hight, were set far enough in so it didnt twist and pull them making them not level with each other etc. Took all day, 10-2 4-7 to get it right.
