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