A support structure and vertical isolation structure may include a plurality of spring coils and a mesh network. Each spring coil of the plurality of spring coils includes a spring, a cap, and a floating connector. The cap is configured to engage the spring. The floating connector is disposed in a middle of the spring. The mesh network secures a first spring coil of the plurality of spring coils to a second spring coil of the plurality of spring coils by passing through the floating connector of each of the first spring coil and the second spring coil.

A non-flip mattress with top side and bottom side and depending edges; wherein the bottom side is covered with a flame-resistant, highly needled, double-sided-calendered, needlepunch nonwoven fabric that passes 16 CFR 1633. The nonwoven fabric is a double-calendered, 80/20 polyester/flame-resistant rayon blend needled with a minimum of 190 punches per cm.sup.2 and with increased tensile strength.

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 sleet 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.

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 multilayered, adjustable mattress system with orbital springs comprised of a removeable, fire resistant cover for enclosing the top of the mattress, a zipper having a predetermined zipper track along the bottom of the mattress, wherein the zipper can unzip the removable cover in both directions, a top foam cover, and an open box, rectangular, mattress encasement divided into two head sections, two body sections, and two feet sections. The layers of the mattress include multiple foam layers of varying compressibility, and a rubber spring deck, where the orbital springs are arranged in a honeycomb pattern. Additionally, the layers of the mattress can be interchanged vertically and horizontally within the mattress sections.

An adjustable mattress has a comfort layer and support layer that are separable, replaceable and able to be arranged individually for obtaining the level of hardness and comfort most suitable to a user's desire. An adjustable mattress consists of a comfort layer, a support layer, uniting parts, and springs. The comfort layer is a surface layer on the mattress that can be made from materials of foam or latex or fiber or gel or spring, recycled foam, recycled latex (rebounded) or wrapped spring of various diameters and heights, support layer containing springs, wrapped springs or arranged springs inside the foam as parts of the support layer, the uniting part can be in the form of magnet and iron plate, zipper, button or Velcro placed in the comfort layer and support layer.
