A vehicle seat cushion inflatable insert 110, has one or more layers 801,802 each comprising a pair of flexible material sheets bonded together with join lines (103, fig 1) in a central plane (A, fig 1) between the sheets. One layer is a fluid supply layer having a wider bladder 812a, 812b, 812c joined by narrower conduits 810a, 810b, 810c to a fluid supply opening (107, fig 2) such that the bladders expand perpendicularly to the central plane to a greater degree than the conduits during inflation. A manifold 1004 can connect conduits, and a stacked auxiliary layer (806, 200, figs 3 & 7) connect to a bladder via apertures (205, fig 3).
