A process for making a cushioning component from a pair of sheets of flexible thermoplastic resin in which the sheets are placed against a pair of molds having hemispherical protrusions for forming opposing hemispherical indentations in the sheets. The indentations in the first sheet abut those of the second sheet when the sheets are joined to complete the cushioning component. During the process, inserts may be positioned on the protrusions before the sheets are placed in the molds, and the inserts then may be adhered to the indentations during molding.
