A seat arrangement which provides adjustable support has a wire frame structure (1) mounted in a seat in order to support the cushioning material of the seat. Side boundaries of the frame structure are provided by wire portions (2) that extend generally parallel to one another. A first cushion supporting wire element (13) extends transversely with respect to said frame structure (1) and is pivoted thereto about a transverse axis. A second cushion supporting wire element (10) is pivoted with respect to the first wire element (13) about a second axis transverse with respect to the frame structure (1) and actuating means (16, 17) is provided for applying a force between the said two wire elements (10, 13) to cause articulation thereof about said second axis with movement of the second wire element (10) relatively to the frame structure in a direction generally parallel to the side boundaries thereof (2). The contour of the cushion support provided by the wire frame structure (1) can thus be varied.
