A vehicle seat comprises a base frame including front and rear transverse support members, a backrest, and a seat pan. The seat pan has a rear part mounted on the transverse support members adjacent to the backrest for angular movement about a transverse horizontal axis and a front part which is mounted for angular movement relative to the rear part between a position in which its top surface is co-planar with the top surface of the rear part and a position in which the front edge of the front part is lower than its rear edge when the rear part is substantially horizontal. The distance between the front transverse support member and the rear edge of the rear part of the seat pan is less than two thirds (preferably less that half) of the distance between the front edge of the front part of the seat pan and the rear edge of the rear part of the seat pan, in order to leave room for a seat occupant to stand upright when the seat pan is raised.
