Abstract: A passenger seating unit for a vehicle, such as an aircraft, includes a privacy shell and a door. The privacy shell at least partially defines a passenger seat area, and the privacy shell includes an opening for allowing entry to and exit from the seat unit. A passenger seat may be provided in the passenger seat area. The door is supported on the privacy shell and includes a first panel and a second panel. The second panel is pivotably connected to the first panel such that the second panel is movable relative to the first panel between a folded position and an unfolded position. In the folded position, the door is movable in a forward and aft direction relative to the privacy shell.
