ABSTRACT:
The method of making a therapeutic mattress comprised of taking a first sheet of fabric material of rectangular shape, then taking a second sheet of fabric material and folding it over to provide a top cover and an underlying intermediate bottom fabric cover of the same dimensions as the first sheet; and thereafter, applying a plurality of parallel spaced rows of stitching across the width of the top cover and intermediate bottom cover. Further steps include, superimposing the folded over second fabric sheet over the first fabric sheet and peripherally stitching the top fabric cover, the intermediate bottom fabric cover and the bottom fabric cover together defining a series of rectangular tubes within the top cover and intermediate bottom cover, and a unit chamber between the bottom intermediate cover and the bottom cover. Additional steps include, stuffing, filling, compacting and retaining a fibrous material within the plurality of rectangular tubes, defining a plurality of firm resilient top mattress sections; and stuffing, filling, retaining a resilient fabric material within the chamber defining a bottom mattress section supportably underlying the top mattress sections; and transversely stitching closed the open ends of the tubes and chamber.
