Abstract: A bedding foundation having a nestably stackable spring assembly, including a border wire. The foundation's spring assembly may be nestably stacked with numerous other such assemblies for transportation, thereby avoiding the need to compress and tie the assembly for shipping. Each spring assembly includes support wires having alternating peaks and valleys along with stabilizer wires having alternating peaks and valleys. The valleys of the stabilizer wires are secured to the valleys of the support wires. The peaks of the stabilizer wires are secured to longitudinal wires extending parallel the sides of the border wire.

Abstract: A bedding or seating product comprises a pocketed spring assembly comprising a plurality of parallel strings of individually pocketed springs. The product may have individual inserts between adjacent strings of springs. Adjacent individually pocketed springs are separated from each other by at least one separating seam. Each of the separating seams comprises a pair of Y-shaped or U-shaped seams which may be joined together or spaced apart.

Abstract: Disclosed herein is a method of making a spring core (12) for a bedding or seating product (10). The spring core (12) has coil springs (26) having unknotted end turns (72, 74) made from high tensile strength wire. In each embodiment, the end turns (72, 74) of the coil springs (26) are generally U-shaped having one arcuate leg (76) longer than the other (78), the legs (76, 78) being joined by a connector (80) having an arcuate bump (81) therein. The springs (26) are oriented in the spring core (12) such that a long leg (76) of one end turn (72) abuts a short leg (78) of the adjacent end turn (72) prior to being wrapped in helical lacing wire (32). The high tensile wire enables the coil springs (26) to be manufactured using less wire than heretofore possible.

Abstract: A bedding or seating product comprising a spring core including upper and lower border wires. Each of the border wires is generally rectangular in cross-section to reduce wire costs without compromising beam strength of the border wire. Each row of springs of the spring core may be made of a single piece of wire. The rows of springs may be arranged in side-by-side rows and columns and be connected with each other by helical lacing wires.

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 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 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 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.
