Passenger seat assemblies may be used in vehicles such as aircraft. The passenger seat assembly includes a first wall, a second wall opposite from the first wall, and a passenger seat having a first side and a second side opposite from the first side. The passenger seat is positioned between the first wall and the second wall. The passenger seat assembly is positionable between a forward-facing configuration and an aft-facing configuration. In both the forward-facing configuration and the aft-facing configuration, the first wall is proximate to the first side of the passenger seat and the second wall is proximate to the second side of the passenger seat.
