Unveiled at the recent Airliners Interiors Expo in Hamburg, Germany, the seats, which are designed to allow for more people and less luggage in the cabin interior, are expected to face criticism at least from passengers.

This design comes on the heels of other controversial plans to maximize the space inside of airplanes with one airliner considering doing away with seats entirely, making passengers stand for the length of the flight and another scheme that would consider bar-stool-like seating for its passengers.

However, aviation authorities have not approved any of the vertical seating proposals.
