A passenger accommodation assembly for a passenger vehicle can be configured as a column oriented parallel to an axis defining a forward and a backward direction. The column can include at least a second seat positioned behind a first seat. The first and second seats can each be oriented to face toward the axis in directions not substantially parallel to the axis and can each be convertible by a relative movement of elements of the seat between a sitting mode and a bed mode in which elements of the seat form at least part of a sleeping surface. When in the bed mode, the second sleeping surface can be situated higher or lower than the first sleeping surface such that at least a portion of the second sleeping surface vertically overlaps with at least a portion of the first sleeping surface.
