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 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 spring core is provided that includes a plurality of coil springs having an upper portion and a lower portion that collectively define an interior cavity. The spring core further includes a continuous upper fabric layer that covers each coil spring and defines a recess in the interior cavity of each coil spring. A cushioning layer is positioned atop the continuous upper fabric layer and extends into the recess in the interior cavity of each coil spring. A mattress assembly is further provided that includes the spring core, an upper body supporting layer, and a lower foundation layer. Methods of producing a spring core are further provided.

An elastic pad for furniture can be customized and assembled by a user. The elastic pad includes an outer cover, an elastic module layer and at least one elastic pad layer. A side enclosure of the outer cover is detachably connected with a top cover body, and the side enclosure is detachably connected with the bottom cover body. The elastic pad is configured to allow a user to select a desired type and/or a desired number of elastic module layers and elastic pad layers, and to further select the side enclosure based on a thickness of the elastic module layer and elastic pad layer, and assemble the top cover body, the bottom cover body, the selected side enclosure, and the selected elastic module layers and elastic pad layers together to obtain the elastic pad.

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.

A balancing pad for furniture includes a pad body having a first pad surface with receiving holes extending in the thickness direction of the pad body. Each receiving hole is configured to receive a portion of a corresponding elastic module of an elastic base pad, to restrict movement of the elastic modules in the transverse direction of the pad body. A second pad surface is provided with a vent structure. After assembled to form an elastic pad, the balancing pad restricts movement of elastic modules and allows the elastic pad to be rapidly restored with good support properties. The balancing pad can improve stability, recoverability and support performance, providing higher comfort and a more hygienic environment.

A pocket coil spring assembly is provided that includes a coil spring having an upper portion and a lower portion collectively defining an interior cavity of the coil spring. The pocket coil spring assembly further includes a fabric pocket encasing the coil spring with a top area covering the upper portion of the coil spring and a bottom area covering the lower portion of the coil spring. An amount of flexible foam is positioned in the interior cavity of the coil spring such that a top surface of the flexible foam extends above the coil spring. A mattress assembly is further provided that includes a plurality of the pocket coil spring assemblies.

An elastic pad includes a pad body having a set of elastic modules and at least one replaceable pad layer stacked in a vertical direction. An outer covering is configured to cover the pad body. The outer covering includes a top covering portion, and a side enclosure covering portion connected via a detachable structure which allows disassembly or assembly of the side enclosure covering portion. The top covering portion covers a top surface of the pad body, and the side enclosure covering portion encloses and covers side surfaces of the pad body. The side enclosure covering portion can be disassembled and assembled to allow replacement of the pad layer without changing the set of elastic modules and the top covering portion. Elastic pads differing in thickness and hardness may be used, while improving comfort and cleanliness.

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.
