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 thicker and more rigid than the scrim sheet.

An apparatus and method are provided for a sofa seat cushion comprising a cushion core including a multiplicity of pocketed springs enclosed within an upholstery foam envelope. The pocketed springs are positioned side by side in a spring layer arrangement and are independently operable. A memory foam layer positioned above the upholstery foam envelope comprises a material capable of molding to a person's body sitting on the sofa seat cushion and then quickly returning to an original shape once the person leaves the sofa seat cushion. The memory foam layer comprises a gel-infused visco-elastic memory foam with a polyethylene terephthalate layer positioned there above. Directly below the upholstery foam envelope is an upholstery-grade polyurethane foam layer with a polyethylene terephthalate layer positioned directly thereunder. An exterior upholstery surrounding the cushion core provides a plush seating surface.

The present disclosure provides a spring module for a spring cushion of furniture and a spring cushion having the same, the spring module may comprise a spring and a spring bracket for accommodating the spring, and the spring bracket may comprise a base, an end cover and a flexible connecting part connected therebetween, the spring may be fixed in the spring bracket with a predetermined initial pressure. The present disclosure further relates to a spring cushion having the spring modules.

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.

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.

The present disclosure provides a spring module for a spring cushion of furniture and a spring cushion having the same, the spring module may comprise a spring and a spring bracket for accommodating the conical spring, and the spring bracket may comprise a base, an end cover and a flexible connecting part connected therebetween, the spring may be fixed in the spring bracket with a predetermined initial pressure. The present disclosure further relates to a spring cushion having the spring module.

A spring module for a furniture cushion includes a conical spring and a double-layer flexible sleeve. The double layer flexible sleeve has a frustoconical first outer layer having a first closed top end, a first open bottom end, and a first outwardly extending flange at the first open bottom end. A frustoconical second inner layer inside the frustoconical first outer layer has a second closed top end, an open second bottom end, and a second outwardly extending flange at the open second bottom end of the frustoconical second inner layer. The conical spring is between the first outer layer and the second inner layer. The spring module may be attached to a base having locking structures for locking adjacent spring modules together.

A spring module includes a spring and a spring bracket for accommodating the spring. The spring bracket may have a base, an end cover and a flexible connecting part connecting the base and the end cover. The spring may be fixed in the spring bracket with a predetermined initial pressure. The spring module may be used in a spring cushion for furniture.

The present disclosure provides a spring module for a spring cushion of furniture and a spring cushion having the same, the spring module may comprise a spring and a spring bracket for accommodating the spring, and the spring bracket may comprise a base, an end cover and a flexible connecting part connected therebetween, the spring may be fixed in the spring bracket with a predetermined initial pressure. The present disclosure further relates to a spring cushion having the spring modules.

An elastic mattress, the elastic mattress includes one or more elastic modules, one or more bottom layers disposed on a lower side of the one or more elastic modules, and one or more lap joints. The one or more elastic modules comprises a plurality of pre-compressed springs, connecting members are disposed on middle parts of the plurality of pre-compressed springs, corresponding ones of the middle parts on adjacent pre-compressed springs of the plurality of pre-compressed springs are connected together, the connecting members are connected to the one or more lap joints, the one or more lap joints are connected to the adjacent pre-compressed springs, and bottom surfaces of the plurality of pre-compressed springs are connected to the one or more bottom layers.
