This type is equipped with Airbus Airspace interiors which include wider cabins and larger overhead lockers.
Seats located at the front of the cabin are sold as Business Class with the centre seats blocked. As is standard in European aviation, the Business section is sized dynamically where the dividing curtain moves forward/aft in accordance with demand, capped at a maximum of 24 seats (6 rows).

Please note, the seat plan illustrated here while developed from a KLM published layout of passenger accommodation diagram, has not yet been fully scrutinised by aeroLOPA so some discrepancies may be present albeit relatively minor.
