a perch member selectively deployable either;
in a first condition, where the perch member is configured as an extension of the seat back to provide back support for the occupant when in the lower position, orin a second condition, where the perch member is configured as an additional base member to provide another seating surface for an occupant when in the upper position;
a fastener for securing the perch member when in the second condition; and
a linkage extending between the seat back and a point on the perch member substantially towards a lowermost end of the perch member, the linkage being arranged to lock when the perch member is configured into the second condition such that the linkage acts as a strut supporting weight of an occupant.

Abstract
A seat for a vehicle is configured such that an occupant can be seated in either a lower position or in an upper position.
