Abstract: An innerspring assembly comprising at least two sets of coil springs. In one embodiment, a first set of coil springs has a first elevation, a second set of coil springs has a second elevation different from the first elevation, and wherein one of the first and second sets of coil springs is compressed upon initial loading of the innerspring assembly, and wherein each of the first and second sets of coil springs is compressed upon continued loading of the innerspring assembly. In another embodiment, a first set of coil springs is pre-loaded to a first compressed state and a second set of the coil springs is pre-loaded to a second compressed state that exhibits a different degree of firmness relative to the first compressed state. In yet another embodiment, a first set of the coil springs has a barrel-shaped outer profile while a second set of the coil springs has an hourglass-shaped outer profile.

Abstract: An innerspring assembly comprising a plurality of strips of pocketed coil springs, each including axially interconnected spring pockets having a pocket height. The strips of pocketed coil springs are comprised of overlapping plies of material adjoined together by axially offset cross seams extending generally along the pocket height to define the spring pockets, with each spring pocket containing a coil spring. In one embodiment, the overlapping plies of at least two strips are coupled together by connecting seams extending along the pocket height and axially offset from the cross seams. In another embodiment, the overlapping plies of at least three strips are interconnected. In another embodiment, overlapping edges of the plies of material are adjoined by a closing weld seam positioned adjacent an end surface of the pocketed coil springs, with the overlapping plies of material of at least two strips interconnected by connecting welds positioned along the pocket height.

Abstract: A coil spring assembly is provided that includes rows of pocketed coil springs, a top securing sheet and a bottom securing sheet. The assembly may be partitioned into sections of varying firmness. The rows of coil springs are positioned between the top and bottom securing sheets. Coil spring assemblies are provided that further include top and bottom securing members that further stabilize the pocketed coil springs.

Abstract: An improved cushion or mattress assembly is disclosed including side boxing sections which are glued to top and bottom sections thereby defining a cavity. Prior to glueing the top cover to the assembly, an insulation layer is inserted into the cavity defined therein and glue is applied to the top side of the insulation piece. A string of encased springs is then placed on top of the insulation piece. A second insulation piece with glue applied to the underside is placed on top of the encased spring array in the cavity. The top cover then is glued on the cushion assembly. The entire cushion assembly may be fiber or down covered and encased in a fabric, plastic, leather, or vinyl outer covering. The springs contained within the spring encasement assembly include an hourglass or dual radius contour and are heat treated or mormalized to provide improved stiffness and prolonged life.

Abstract: A spring cushion structure with a plurality of hour-glass shaped spring coils arranged in columns and rows with adjacent springs within a row connected at the top and bottom by a helical wire extending between adjacent columns and with the marginal coils attached at the top to a border wire extending around the assembly. A transparent sheet is placed between the bottoms of the assembly and support sinuous wires which are bent to provide an upwardly extending integral suspending arm and bent again to provide an outwardly extending shepherd hook shaped attachment arm which is attached to a wood frame surrounding the periphery of the entire structure.
