The outer carriage has a cushion carrier frame carrying a fixed cushion and a folding cushion, which carrier frame is connected to the outer carriage by a lever system for adjusting the carrier frame from a lowered position when the carriages are in the chair position to a raised position when the carriages are moved into the cot position. A platform is hinged to the inner carriage at an end thereof close to the head cushion for receiving thereon the folding cushion in the cot position of the carriages, and movable supporting elements connected to the lever system being provided for moving the platform to an essentially horizontal position when the carriages are moved into the cot position, which elements are adapted to support the platform when the lever system is in a dead center or over-center position when the carrier frame is in the raised position.
