    Abstract: A mattress is disclosed comprising a flexible frame for bearing uniaxial compressive stress from a human body pressed onto the frame. The frame traverses the breadth and length of the mattress in evenly-spaced repeating patterns which defines hollow recesses filled with materials like silicone gel, memory foam, coils, and springs. The flexible frame in some embodiments, has a higher compressive strength than does the traditional material(s) filled the recesses defined by the frame. The indentation force deflection (IFD) rating varies slightly across small, repeating regions the surface of the mattress. These regions provide lumbar, thoracic, and pelvic support to a user. A user may move about on the mattress during the night to adjust the areas of the small regions pressing most firmly against the body, selectively adjusting both the position of the body and the pressure points of the mattress to maximize comfort.

Each of the border wires is generally rectangular in cross-section to reduce wire costs without compromising beam strength of the border wire. Each row of springs of the spring core may be made of a single piece of wire. The rows of springs may be arranged in side-by-side rows and columns and be connected with each other by helical lacing wires.

  • Patent number: 8490232
    Abstract: A bedding or seating product comprising a spring core including at least one border wire and a plurality of coil springs. Each of the border wires is generally rectangular in cross-section to reduce wire costs without compromising beam strength of the border wire. Each of the coil springs may be made of a single piece of wire having a central spiral portion defining a central spring axis and terminating at opposed ends with upper and lower end turns. The coil springs may be arranged in side-by-side rows and columns and be connected with each other at the upper and lower end turns by helical lacing wires.

  • Patent number: 8438681
    Abstract: A furniture device comprising a section, having a fundament, a plate member, a first set of elastic members, an array of connections, a plurality of connection members attached to the first set of elastic members and to the fundament and a deformation member adapted to displace the plate member. Each elastic member comprises an elastic element having a first spring constant and a flexible envelope that encloses the elastic element. The connections located between the upper and lower ends of the elastic members forming an upper part with an upper length extending between the upper ends of the elastic members and the connections, and a lower part extending between the connections and the lower ends of the elastic members. The upper length is mainly unaffected by the displacement of the plate member and the lower length is adjustable by means of the displacement of the plate member.

  • Publication number: 20130104311
    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.
