The early A109s have a seating capacity of 8. That's 2 up front, of course, and three not-too-wide seats at the rear of the cabin looking forward. Most cabin configurations feature two seats, rear facing and back-to-back with the front seats. So a total of 7.
However.... Agusta (used to anyway) had a bus-seat config that was a three place, again not-very-wide, bench seat forward facing, and picking up on the same hard points for the conventional quasi 'Club' seat. It wasn't very useful, frankly, and payload in the early models meant very short flights if you had 8 up
(Not much fuel!)
The only use I saw it ever put to was for FOIs to sit and monitor the crew's performance............
just being a pedant!
