A device for a seat, in particular an aircraft seat, the seat having a back that pivots between an upright sitting position and a folded-down sleeping position, the device serving to cause the seat proper of the seat to take up an appropriate position that matches that of the back. The device includes two support-and-drive assemblies designed to be disposed laterally on either side of the seat, each assembly having first and second hinged and deformable mechanical linkages designed to be associated mechanically firstly with the back to pivot relative thereto, and secondly with the seat proper in portions thereof that are respectively proximal and distal relative to the back. The linkages support the seat proper and couple movement of the back and of the seat proper in such a manner that when the back passes from its sitting position to its sleeping position it causes at least an upward movement of the seat proper and that, conversely, when the back moves from its sleeping position to its upright sitting position, it causes at least an opposite downward movement of the seat proper.
