| 20130232689 | BOX SPRING ASSEMBLIES EMPLOYING FOAM CUSHIONING GRIDS, AND RELATED COMPONENTS, MATTRESS ASSEMBLIES, AND METHODS - Box spring assemblies employing foam cushioning grids, and related components, mattress assemblies, and methods are disclosed. Foam cushioning grids are comprised of a plurality of foam grid members that are interconnected to form the foam cushioning grid. By interconnecting the foam grid members, a plurality of voids may be disposed between the interconnecting foam grid members as part of the foam cushioning grid. In this manner, as a non-limiting example, the foam cushioning grid can be disposed on a wire grid, such as in box springs, to provide cushioning support for the wire grid, as one non-limiting example. A load placed on the wire grid will be cushioned by the foam cushioning grid disposed therebetween. Further, as a non-limiting example, voids in the foam cushioning grid allow air to easily flow between the interconnected foam grid members. | 09-12-2013 |

| 20080244828 | Mattress foundation with perimeter structure - 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. | 10-09-2008 |
| 20100175185 | Bedding Foundation Having Nestable Stackable Components - A stackable wire core assembly for a bedding foundation which may be nestably stacked with numerous other such assemblies for transportation, thereby avoiding the need to compress and tie the assembly for shipping. The wire core assembly includes an upper wire grid including a border wire and support wires extending between the ends of the border wire. Each support wire has resilient portions extending downwardly from the plane of the upper wire grid, each resilient portion having a flat bottom adapted to be secured to a wooden base frame and curved arms extending upwardly from opposed ends of the flat bottom. | 07-15-2010 |
| 20110314601 | Bedding Foundation Having Border Wire With Generally Rectangular Cross-Section - A bedding foundation having a nestably stackable spring assembly including a border wire having a generally rectangular cross-section. The foundation's spring assembly may be nestably stacked with numerous other such assemblies for transportation, thereby avoiding the need to compress and tie the assembly for shipping. Each foundation assembly includes a number of corrugated support wires having alternating peaks and valleys. The border wire is generally rectangular in cross-section to reduce wire costs without compromising beam strength of the border wire. | 12-29-2011 |
| 20120110732 | Bedding Foundation Having Nestably Stackable Spring Assembly Welded To Border Wire With Generally Rectangular Cross-Section - A bedding foundation having a nestably stackable spring assembly, including a border wire having a generally rectangular cross-section. The foundation's spring assembly may be nestably stacked with numerous other such assemblies for transportation, thereby avoiding the need to compress and tie the assembly for shipping. Each foundation assembly includes a number of corrugated support wires having alternating peaks and valleys. The border wire is generally rectangular in cross-section to reduce wire costs without compromising beam strength of the border wire. | 05-10-2012 |
