A body support structure includes a structural lattice structure having a first stiffness, and a compressive lattice structure supported by the structural lattice structure and having a second stiffness less than the first stiffness. A skin lattice structure is supported by the compressive lattice structure, wherein the skin lattice structure is resistant to shear deformation in response to a normal force and is expandable in a direction transverse to the normal force.

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.

Furniture is assembled from elastic modules enabling rapid and convenient assembly and disassembly. The elastic module has a spring, an outer covering layer, and an end member attached to an end face of the outer covering layer. A mattress includes a plurality of individual spring assemblies (145), with each spring assembly including at least one spring (134) and a spring cap (144, 150, 161, 164, 171, 184, 194, 204). Each spring cap has at least one first attachment fitting (168, 178, 174, 186, 196) and at least one second attachment fitting (169, 180, 176, 187) with each first attachment fitting engageable into or onto and removable from a second attachment fitting of an adjoining spring cap. The spring assemblies are attached to each other via the first and second attachment fittings, forming the individual spring assemblies into a spring core. A top pad is positioned on top of the spring core.

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.

The spring assemblies are attached to each other via the first and second attachment fittings, forming the individual spring assemblies into a spring core. A top pad is positioned on top of the spring core. The mattress can be quickly dis-assembled and stored in a compact space by removing the top pad and separating the spring assemblies from each other.

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.

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.

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.

The invention relates to a height-adjustable supple member for lying and/or sitting furniture, including one or more adjustable springs and a rotary part. Each adjustable spring is configured to change in height along a central axis under the effect of a radial stress relative to the central axis. The rotary part includes one or more rails each extending over an angular sector about the central axis, in a plane perpendicular to the central axis, from a first end to a second end more distant from the central axis than the first end. Each rail cooperates, in the radial direction relative to the central axis, with a corresponding adjustable spring among the one or more adjustable. The rotary part is able to rotate, about the central axis, so as to exert, through each rail, said radial stress on the corresponding adjustable spring.
