On the seat backs, there’s 2 bolts to each of the sides at the top of the seats. (Usually the seatbelt covers them). Then the back hinges down the same as it does in an ADV.
if you want to completely remove the seats, then from there, you’d remove the bolts at the hinge points on the bottom and back of the seats the little cushion in between them just clips on to a plastic lip in the back wall and you can just pull it off.
