Abstract: A pocketed spring assembly comprises a plurality of parallel strings of individually pocketed springs. A dimensionally stabilizing substrate is secured to at least some of the strings on one of the top and bottom surfaces of the strings. A scrim sheet is secured to at least some of the strings on an opposed surface of the strings to maintain the positions of the strings. The dimensionally stabilizing substrate is laterally rigid enough to maintain length and width dimensions of the coil spring assembly. However, the dimensionally stabilizing substrate is flexible enough to allow the pocketed spring assembly to be roll packed for shipping.

Abstract: A pocketed spring assembly comprises a plurality of parallel strings of springs, each string joined to at least one adjacent string, each string comprising first and second opposed plies of fabric and a plurality of pockets formed along a length of the string by transverse seams joining the first and second plies. At least one spring is positioned in each pocket. Exterior strings have identical springs in their pockets. Interior strings have two different springs along their length, the outermost springs being firmer than the interior core springs. The pocketed spring assembly has increased firmness or edge support along all four sides due to the different coil springs of the assembly.

Abstract: A pocketed spring assembly comprises parallel strings, each string joined to at least one adjacent string. At least some of the strings have springs of different gauge wire and some of the pockets of the strings having springs of different gauge wire are spliced together. At least some of the strings have springs of different geometries and some of the pockets of the strings having springs of different geometries are spliced together. At least some strings may have end sections with springs different than a middle section therebetween, the springs of the end sections being firmer than the springs of the middle section.

Abstract: A posturized comfort layer for a bedding or seating product has different sections of different firmness due to different mini coil springs within the sections. The springs may be individually pocketed between two sheets of non-woven polypropylene fabric joined with circular or rectangular weld seams. Regardless of the shape of the weld seams, the different firmness of the different sections of the comfort layer may be due to different mini coil springs contained in the pockets. All pockets may have the same spring, the springs may be contained in different size weld seams to create pockets of different heights.

Abstract: A pocketed spring comfort layer for a bedding or seating product has pockets characterized by the individual mini coil springs of the comfort layer being pocketed with between at least one cushion assembly and a sheet of polypropylene fabric. Each cushion assembly includes at least one foam layer. A segmented seam joins the cushion assembly and the sheet of polypropylene fabric around each of the mini coil springs of the pocketed spring comfort layer. The method of making the pocketed spring comfort layer includes compressing the mini coil springs and creating pockets with a welding horn and an anvil.

Abstract: A posturized comfort layer for a bedding or seating product has different sections of different firmness due to different mini coil springs within the sections. The springs may be individually pocketed between two sheets of non-woven polypropylene fabric joined with circular seams or rectangular seams. Each circular seam joins opposed pieces of fabric around one of the mini coil springs with curved segments. Alternatively, rectangular seams join opposed pieces of fabric around each of the mini coil springs with linear segments. Regardless of the shape of the seams, the different firmness of the different sections of the comfort layer may be due to the mini-coil springs contained in the pockets.

Abstract: A pocketed spring assembly comprises a plurality of parallel strings of individually pocketed springs. Each string is joined to at least one adjacent string. Each string has first and second opposed plies of fabric and a plurality of pockets formed along a length of the string by transverse seams joining the plies. At least one spring is positioned in each of the pockets. The double-layered fabric used to make at least some strings comprises two layers of non-woven spunbonded polypropylene fabric to reduce noise. The layers may be ultrasonically welded or point bonded together.

Abstract: A comfort layer for a bedding or seating product has slow-acting pockets characterized by the individual springs of the comfort layer being pocketed with either semi-impermeable or non-permeable fabric. Each seam joining opposed plies of fabric around each of the coil springs of the comfort layer may be segmented, allowing air to flow between the segments, thereby increasing the luxury “feel” of the comfort layer. The method of making the comfort layer includes compressing the springs and creating pockets with a welding horn and an anvil.

Abstract: A pocketed spring assembly comprises a plurality of parallel strings of springs held together with tabs. Longitudinal seams joining overlapping tabs extend generally the same direction as the strings of springs. Pockets are formed along a string of springs by aligned separating seams. At least one spring is positioned in each pocket. Each separating seam joins opposed plies of the string and keeps the spring in its pocket. Ends of aligned separating seams are spaced from each other, thereby improving airflow between pockets.
