  • Publication number: 20100325806
    Abstract: A pressure dispersion system includes a pressure dispersion pad and a pressure dispersing mattress system for body support and sleep. The pressure dispersion pad and pressure dispersing mattress systems reduce pressure points from a supported body to less than approximately 32 mm Hg to reduce or eliminate capillary closing and a resultant reduction in pressure concentration and resultant discomfort and repositioning during sleep. Empirical design from human body pressure mapping is used to identify support zones for which components are selected and assembled in the pressure dispersion support systems for pressure dispersion and relief. In a pressure dispersion support system in the form of a mattress, multiple zones are defined by arrangement of different kinds of support materials, including foam tops such as memory foam or moderate to low density polyurethane, and secondary foam layers or foam base of relatively higher density polyurethane and latex.

    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.

One or more top layers of foam rubber are mounted on the foam encasement over the spring unit and are secured thereto using additional plastic fasteners. An outer layer of quilted cotton material is sewn over the foam encasement and top layers of foam rubber to yield the finished one-piece mattress. As can be appreciated, the outer periphery of the mattress is defined by foam material, which is substantially rigid in its construction, rather than the spring unit, which is highly susceptible to warping. In this manner, the foam material serves to preserve the shape of the outer periphery of the mattress over time.

  • Patent number: 7386897
    Abstract: Disclosed herein is a bedding or seating product having a spring core comprising coil springs having unknotted end turns made from high tensile strength wire. In each embodiment, the end turns of the coil springs are generally U-shaped having one leg longer than the other, the legs being joined by an arcuate connector. The springs are oriented in the spring core such that a long leg of one end turn abuts a short leg of the adjacent end turn prior to be wrapped in helical lacing wire. The high tensile wire enables the coil springs to be manufactured using less wire than heretofore possible.
