ABSTRACT OF THE DISCLOSURE A support that may be either in the form of a cushion or chair in which the portion thereof in contact with a specific user conforms to the body contour of the user, with the support being of hollow construction and filled with a resilient material such as a foamed poly- merized resin or the like. The exterior surfaces of the support are enveloped in an envelope of a resilient material. The support is formed by having a user sit upon a bag of pliable sheet material, which bag is partially filled with a flowable granular material. A partial vacuum is applied to the interior of the bag to maintain it in the configuration to which it was deformed by the weight of the user. The bag is now coated with a liquid or paste material that solidifies. After solidification the granu- lar material or the complete bag is removed through a small opening in the bag, or in the solidified material surrounding the bag and the interior of the bag or the cavity formed by the solidified material has a liquid resin mixed with a catalyst introduced therein in a sufficient quantity to fill the interior of the bag when it polymeri- zes into a foamed resin. The solidified envelope is removed from the foamed resin filled bag or cavity. The bag or resulting form is now coated with a film of inert material such as resilient rubber or other substance. The finished support may be used in either a stationary position or mounted on a mobile unit.
