Abstract
A method for forming a foamed innerspring unit is provided including releasably securing a plurality of coils (20) to a jig (22), delivering a foamable reaction mixture (26) to a tray (10 or 10") and positioning the jig so that the ends of the coils extending away from the jig are spaced from the bottom of the tray so that the rising foam embeds the end of the coil. The process is repeated by releasing the foamed layer embedding one end of the coils, releasably holding the first foamed layer with the ends thereof spaced from a tray having said foamable reaction mixture therein so that the second end of the coils is embedded in a second foam layer. A mattress formed of a plurality of innerspring unit sections formed in accordance with the foregoing may be combined with in a cover to define a mattress. By selecting the firmness of the coils of adjacent sections, regions of differing firmness can be provided in the mattress.
