  • Patent number: 10485357
    Abstract: A mattress having a foam core is provided. The foam core may include a channel along two or more sides of the foam core. Spring coils in the channel(s) provide increased localized support proximal the outer edge of the mattress. The spring coils may be conventional spring coils or individually pocketed spring coils. In certain alternatives, the spring coils may be replaced by foam different than the foam core; such difference may include foams having a higher indentation force deflection (IFD) rating. The mattress may have a foam core that is provided with an undercut filled with a foam insert where a higher IFD foam is provided in the undercut.

  • Patent number: 9867477
    Abstract: A mattress includes a spring extending between first and second points to provide a first spring rate in a first direction. A polymer fiber structure is provided between the first and second points and adjoins the spring. The polymer fiber structure includes fibers interlinked with one another to provide the second spring rate in the first direction. An example method of manufacturing a mattress is provided that includes arranging springs to provide a mattress innerspring. A polymer fiber structure is introduced in a first state to the innerspring to provide an assembly. The assembly is further processed and the polymer fiber structure is simultaneously altered from the first state to a second state.

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: An infant mattress fits safely in a crib without any gap between the mattress and the walls or bars of the crib. A ring of memory foam surrounds the supporting foam layers of the mattress and forms a snug fit with the vertical bars of the crib regardless of whether the dimensions of the particular crib or mattress vary from their standard sizes. The memory foam ring intentionally renders the infant mattress somewhat larger than the inner dimensions of the crib. The ring compresses when the mattress is placed in a crib in which opposing side bars are separated by a distance that is smaller than the mattress width. The ring is formed by pouring foam into a rectangular mold around the supporting foam layers. Where the mattress includes pocket coils on the supporting foam layers, the ring of memory foam conforms to the outer row of pocket coils.

At least a portion of side-support members are placed onto at least a portion of the top surface of the perimeter area to provide edge-support for the innerspring assembly or core. In this manner, a greater portion of the side-support members can be disposed in the sleeping area of the innerspring assembly or core since the underlying perimeter area provides spring support to the side-support members. Further, this support can assist in retention and/or recovery of the shape of the side-support members to further prevent or reduce compression set of the side-support members.

  • Patent number: 7845036
    Abstract: An edge support for reinforcing an edge of a spring core is provided. The edge support includes a plurality of engaging members that are movable between flat and folded positions. In the flat position, an engaging member is generally aligned with the rest of the edge support. In the folded position, the engaging member extends laterally from the rest of the edge support. With the engaging members in the flat position, the edge support has a relatively thin thickness allowing the edge support to be rolled which may be beneficial for the shipping and handling of the edge support. During the assembling of the mattress, the engaging members may be moved to the folded position such that engaging members extend inwardly into the spring core between the spring coils of the spring core.

  • Patent number: 7805790
    Abstract: A dual spring support structure for mattresses or other reflexive support structures employs a foam spring in combination with an innerspring or foam core, to provide a multi-mode and multi-structural support surface with a multiple, constant, or complimentary spring rate and support characteristics. Foam springs have geometric cross-sectional configurations with mechanical spring properties which work in concert with the spring properties of foam. Foam springs are used in one embodiment about the perimeter of a wire form innerspring or about the perimeter of a foam core. The foam springs may have a spring rate that is complimentary to, greater than or less than the spring rate of the innerspring or core. Foam springs of different configurations and spring rates can be combined with different types of cores, or used alone to provide a spring or cushioning structure.

  • Patent number: 7788746
    Abstract: A mattress foundation with a perimeter structure has a frame, springs mounted upon the frame, and a grid supported by the springs, and perimeter structure at a perimeter of the frame which extends from the frame to the grid, forming an exterior wall which extends from the frame to a border wire of the grid. When the perimeter structure is made of structural and reflexive material such as closed-cell foam, it co-acts with the grid and springs and provides additional support to the perimeter region of the grid and foundation. The exterior wall of the perimeter structure forms a solid surface over which padding or upholstery is placed.

  • Patent number: 7636971
    Abstract: Dampened and zoned innersprings for use in support systems such as mattresses and furniture have dampening inserts in the form of foam pieces which fit integrally with the springs or coils of an innerspring. Dampened innersprings with one or more foam dampeners inserted between springs or coils of an innerspring, and more particularly foam dampener inserts which are configured to extend between multiple adjacent or aligned springs or coils, and which also have segments which fit between individual turns or convolutions of each spring or coil with which the insert is engaged. Mechanical engagement of the innerspring by the foam dampening inserts insures alignment and registration of the innerspring and foam components, and compression and recoil of the individual coils of the innerspring occurs in conjunction with compression and decompression of the foam dampening inserts.

  • Patent number: 7574763
    Abstract: A stiffening system for the perimeter edges of a foam core mattress comprising a coil spring (or other spring-based) structure disposed along one or more perimeter edges (e.g., one or both side edges, the foot, the head, or a combinations thereof including the foot and both side edges) of a mattress having a foam sleeping area. The perimeter spring structure is rectangular or square in cross-section and provides sufficient stiffness for comfortable seating on the edges of the mattress and is joined to the foam core by planar fabric elements that span the joint between them and are attached to both. The sleep area provides the softness and other salutary effects of a foam sleeping surface while the stiffer spring perimeter element provides the rigidity need for comfortable seating and wear resistance.
