Abstract
A convertible passenger seat headrest for a railway sleeping compartment having a convertible seat and bed arrangement. The headrest is pivotally supported from the compartment wall at its lower end and includes a stowable ladder folded within it when the headrest is in the raised position. When it is desired to make up the upper berth of the sleeping compartment, the headrest can be pivoted outwardly from the wall and the ladder unfolded to form a ladder and step which a passenger can use to climb into the upper berth.
