    Abstract: A configurable foam cushioning structure for providing variable support profiles in mattress components is disclosed, and related mattress assemblies and methods. In one embodiment, a plurality of extruded support members are provided each having a top surface and a bottom surface that extend in an extrusion direction and two end surfaces that extend in a direction transverse to the extrusion direction. The extruded support members are connected to each other in a linear array defining a substantially planar lower surface, with one end surface of each of the plurality of extruded support members is substantially coplanar with the lower surface. In this manner, the structure can be easily extruded as one long, continuous piece, and reconfigured into a structure having a relatively short dimension in the extrusion direction and a relatively long dimension in the transverse direction.

  • Patent number: 8955182
    Abstract: A mattress (22) having a foam core (8) completely extends to the perimeter edges of the mattress wherein side walls (15) of the foam core are compressed inward and held in place using a preferably non-woven strip of fabric (21) or similar non-elastic or non-stretchable material that is wrapped around the side walls of the foam core. A method of wrapping the foam core allows corners (5) of the foam core to be formed under the inward pressure of the non-woven fabric, thereby creating a strong perimeter for the mattress that prevents outward pressure against the sidewalls created by the downward pressure of an individual lying on the mattress from flattening of the mattress by providing more upward pushback against the individual. An optional layer of micro-coil springs (2a) may be located within the foam core to provide more buoyancy and springiness in the mattress.

    Abstract: A body support cushion, such as a mattress, mattress topper or overlay, or pillow, is comprised of a layer of flexible foam and further has a volume of gelatinous material, e.g., elastomer gel, applied to a surface thereof. The gelatinous material alters a physical property, such as firmness or feel, of the layer of flexible foam. The gelatinous material can be applied in a number of ways including, but not limited to a spray application whereupon the spray force can be used to control how much gelatinous material penetrates into the layer of foam. The foam layer may be comprised of reticulated or non-reticulated foam. The foam layer may also be comprised of viscoelastic or non-viscoelastic foam.

  • Publication number: 20140245540
    Abstract: A method of making foam imparts antimicrobial and antiodorant qualities to the foam. Green tea powder is added to the polyol raw materials for making memory foam. The green tea memory foam is used to make pillows, cushions and mattresses. Green tea foam in the top layer of a mattress acts as an antiodorant such that less of the chemical smell of the memory foam is perceived by the user. In addition, the bacteria and mold that would otherwise develop in the moist warmer sleeping environment on memory foam are killed by the green tea additive to the foam. Measurable antimicrobial and antiodorant qualities in the green tea foam are achievable by adding green tea powder constituting less than 2% of the weight of the resulting green tea foam. A neck-support contour pillow is made using memory foam that contains green tea and a green dye.

The first firmness zone at the first face end of the cushion is the most firm, the third firmness zone at the second face end of the cushion is the least firm, and the second one or more firmness zones are of intermediate firmness.

  • Publication number: 20130174350
    Abstract: Mattress assemblies and methods employing foam side support members and cloth members to enclose mattress cores are disclosed. A mattress may include a mattress assembly enclosing a mattress core. The foam side supports of the mattress assembly may be disposed adjacent to a periphery portion of the mattress core to provide additional support, for example, when a user mounts and dismounts from the mattress. The side support members may be thermally bonded to the cloth members to secure the side supports adjacent the periphery portion of the mattress core. In this manner, the side support members may be precisely positioned relative to the mattress core without the need for adhesives or expensive manufacturing equipment to thermally weld the side support members directly to a foam base.

    Abstract: In one embodiment, a mattress comprises a core and a cushion layer positioned above the core. A fibrous air spacer layer is positioned above the cushion layer, and a layer of visco-elastic foam is positioned above the fibrous layer. This permits the fibrous layer to be sandwiched between the cushion layer and the layer of visco-elastic material.

  • Patent number: 8375493
    Abstract: A one piece foam mattress core or innerspring encasement is a single contiguous piece of foam having a mattress core or base and four perimeter side supports and which fits with a mattress core or innerspring to provide an integrated mattress construction. The mattress core or base of the encasement is positioned below the mattress core or innerspring proximate to or against a bottom surface. The mattress core or base and the perimeter side supports are connected along fold lines or grooves in the single piece of foam so that the perimeter side walls can be folded to vertical positions about a perimeter of the mattress core or innerspring. The single piece of foam of the encasement is producible in different sizes to fit with different size mattress cores or innersprings.
