Abstract: An arrangement for shifting a piece of furniture through an opening in a vertical partition, such as a wall of a vehicle includes a linkage system which maintains the orientation of the piece of furniture as it is moved between two extreme positions, wherein one of the positions is offset to be lower than the other position. When incorporated in a vehicle, the lateral offset between the two extreme positions is approximately equal to the height of the floor of the vehicle above a ground surface so that if the piece of furniture is a kitchen unit, such as a stove, its working surfaces will be at the same height for use inside the vehicle as when used in the outer position outside the vehicle.
