Abstract: Various systems and methods for adjusting the firmness of a mattress are described herein. Inflation elements having fingers may be coupled with a spring layer or foam layer of a mattress to provide for inflating or deflating the fingers. Increasing the fluid pressure inside the fingers increases the force required to compress the spring layer or foam layer, ultimately resulting in increasing the firmness of the mattress. Conversely, decreasing the fluid pressure inside the fingers decreases the firmness of the mattress.

Abstract: Various systems and methods for adjusting the firmness of a spring mattress are described herein. Inflation elements having fingers may be coupled with a spring layer of a mattress to provide for inflating or deflating the fingers in the interstitial spaces defined by a group of springs of the mattress. Increasing the fluid pressure inside the fingers increases the lateral pressure on the springs. The increase in lateral pressure in turn increases the force required to compress the springs, ultimately resulting in increasing the firmness of the mattress. Conversely, decreasing the fluid pressure inside the fingers decreases the lateral pressure on the springs, which decreases the firmness of the mattress.

Abstract: A divided mattress is disclosed having multiple sections separated by an expansible divider such that movement atop one section of the mattress is isolated and not felt from the adjacent section.

Abstract: A method of applying at least one web of insulator material to a plurality of spring assemblies is provided. Each web of insulator material is unwound from a roll, passed along a roller and applied to multiple spring assemblies which are passed between rollers. Each web of insulator material is folded around outermost coil springs along longitudinal edges of the spring assemblies. Side portions of each web of insulator material are glued, welded or otherwise permanently secured to a middle portion of the web of insulator material.

Abstract: A roll (54) of compressed materials (14) is provided which has a sleeve (50) formed around a rotatable mandrel (12). The sleeve (50) about which the materials (14) are rolled prevents the roll (54) from radially collapsing. The roll (54) may be removed from the mandrel (12) without tearing or telescoping of the material. In one embodiment the sleeve (50) is corrugated material (38). The corrugated material (38) is around the rotatable mandrel (12) prior to the compressible material (14) being wrapped around the sleeve (50). In another embodiment, the sleeve (58) comprises roll-packing material (32) laminated prior to being wound upon the mandrel (12).

Abstract: A string (12) of pocketed coil springs (14) is formed by inserting compressed springs between upper and lower plies of a folded, preferably thermally weldable fabric (16). The springs are maintaned in a compressed configuration while a longitudinal seam (54) joins the free edges of the thermally welded fabric (16) together. Subsequently, the compressed springs (14) are allowed to relax into an expanded configuration after which a transverse seam (80) is formed in the fabric (16) between the adjacent springs (14) thereby encapsulating each spring (14) within a fabric pocket (86). The string (12) of pocketed coil springs (14) is advantageously formed without the need for reorienting the springs (14) after being inserted between the plies (24,26) of the fabric (16) and thereby avoiding the disadvantages and complications associated with turning or reorienting the pocketed coil spring (14).

Abstract: A bedding or seating product comprises a pocketed spring assembly having a plurality of parallel strings of springs joined to each other. Each of said strings of springs comprises a row of interconnected pockets, each of the pockets containing at least one spring encased in a fabric pocket and with more than one line of attachment between at least selected adjacent pockets. At least one spacer strip or at least one scrim sheet extends between the interconnected pockets of at least one string of springs and is secured thereto to provide stability in the pocketed spring assembly.

Abstract: A bedding or seating product comprising a pocketed spring assembly made up of a plurality of parallel strings of springs joined to each other. Each of the strings of springs comprises a plurality of interconnected pocketed coil springs. The product has multiple sections of differing firmness attributable in part to differing heights of the pockets of the strings of springs. Filler is placed above the lower sections of the pocketed spring assembly.

Abstract: A method of roll packing a variety of compressible materials is provided which prevents the rotatable mandrel about which the materials are rolled from radially collapsing. The method further provides for easy removal of the roll packed material without tearing or telescoping of the material. One embodiment of the present invention provides for wrapping a corrugated material around the rotatable mandrel prior to the compressible material being wrapped around the mandrel. In another embodiment, roll-packing material is laminated prior to being wound upon the mandrel before the compressible material is wrapped around the mandrel.

Abstract: A bedding or seating product comprises a pocketed spring assembly having a plurality of parallel strings of springs joined to each other. Each of said strings of springs comprises a row of interconnected pockets, each of the pockets containing at least one spring encased in a fabric pocket. Some of the pockets contain two coil springs, an outer spring and an inner spring, the inner spring extending between the end turns of the outer spring and being wound generally coaxially with the outer spring. The end turns of the inner and outer coil springs are adjacent one another.

Abstract: A pocketed coil spring unit and associated method of assembly combines top and bottom sheets with bonding of the sidewalls of adjacent rows of pocketed coil springs. With this combination, a posturized spring unit is produced in a commercially efficient manufacturing process. The top and bottom sheets extend perpendicularly to the rows of pocketed coil springs and the adjacent rows of pocketed coil springs are bonded on the sidewalls of the fabric pockets in the absence of the top and bottom sheets. As such, the spring unit can be customized for posturization to provide a firmer supporting foundation at the locations of the top and bottom sheets and a more individualized flexible construction in the regions of the inter-row sidewall bonding.
