Method and device for tailoring the density of a compressible, non-rebounding foam used in capturing anatomical impressions to account for the variations in body weights and sizes, the foam fabricated by the method or device and the custom surface fabricated using the foam. The device is configurable to create a wide range of densities suitable for a wide range of body types. The resulting imprinted foams are then encased in hard surfaces to obtain a mold that provides support surfaces for the back and buttocks in the construction of custom molded chairs, seat cushions and back orthotics. The reduced density foam is suitable for fabrication of orthotics that fit to large areas of the body.
