Different types of seats in a van
I am writing a scene where I need to describe in a fluid manner where the characters are seated in a minivan. I know the seat next to the driver is the passenger seat or shotgun. This is a vehicle with third row seating so I am not sure if the seats right behind the driver are the backseat. If they are, what are the ones behind the backseat called? If not, what are the right terms to describe each point?
If it was already established that there were 3 rows of seats, I would call them
Front seats
Mid seats (mid-passenger-seats)
Rear seats
