A seating platform e.g. for domestic furniture or motor vehicle seats comprise at least one moulded elastic element (12) mounted on a frame member (10) and covered by a non-stretch sheet (14) which, upon installation, is only lightly tensioned. The element (12) is of a substantially incompressible material, e.g. a rubber composition high in natural rubber, and includes spaced apart grooves (12e, 12f) which permit controlled transverse deformation of the element upon loading of the platform. <IMAGE>
