Definitions

  • the present invention and related disclosure is related to bed mattresses, and more specifically to foam bed mattresses having layers of different types of materials.
  • Sleep plays an important role in a person's overall health and enjoyment of life.
  • the quality and quantity of sleep affects the body's ability to function normally and the ability to reach peak performance.
  • Physiologically, sleep affects brain activity, heart rate, blood flow to the brain, sexual arousal, and body temperature. Sleep deprivation shows a strong correlation to obesity, diabetes, stroke, depression, and hypertension. Restful sleep is dependent upon the level of comfort while lying prone. Concentration of pressure on certain parts of the body and poor skeletal alignment arc significant causes of restless sleep. Sleeping on a mattress or other support surface that does not properly support and conform to the shape of the body or to the spine's natural curves may significantly contribute to restlessness or inability to sleep.
  • Multi-layer foam mattresses of the prior art are designed to provide adequate support, without the use of wire springs, and pressure-relieving conformity particularly in the top layer.
  • the first or top foam layer that is in contact with the user is made of visco- elastic foam, i.e., foam which is both viscous in order to conform under pressure, and elastic in order to return to its uncompressed state. Visco-elastic foam is sensitive to body heat such that the material conforms to the user's body, providing a more comfortable sleep surface.
  • Multiple layer foam mattresses come in a variety of forms as the type of material, the thickness of each layer and the density of each layer can be varied to provide a mattress with different support characteristics.
  • ILD Indentation Load Deflection
  • IFD Indentation Force Deflection
  • visco-elastic foams provide the advantages of shape conformity and thermal responsiveness, structural support is thereby sacrificed, particularly in areas of highest load concentrations.
  • the support characteristics of visco-elastic type foam can be altered with density, although increased density produces a very hard and rigid surface without any thermal softening.
  • the thickness of the layers in a multi-layer stack-up can also be determinative of certain support characteristics, although this may be a minimal factor if that is the only variable between layers. For mis reason, in the prior art the number of adjacent layers of visco-elastic foam in a support pad or mattress has been kept to a very minimum, i.e., no more than two based upon the apparent belief that additional layers provide no particular advantage for the added cost
  • the multi-layer multi-material foam mattresses of the present disclosure and related inventions provide novel combinations of multiple layer, multiple material foam layers or stacks which provide unexpected and improved support characteristics and pressure relief and distribution.
  • the multi-layer, multi-material foam mattress contains at least two layers of visco-elastic foam arranged in a stacked arrangement; at least one layer of polyurethane foam located beneath the at least two layers of visco-elastic foam and having a substantially planar top surface and a substantially planar bottom surface opposite the substantially planar top surface; and a support core, located beneath the at least two layers of visco-elastic foam and at least one layer of polyurethane foam, the support core comprising at least three foam layers that are not visco-elastic.
  • the thickness of the first or top layer of the at least two layers of visco-elastic foam is less man the thickness of the second layer of the at least two layers of visco-elastic foam and the thickness of the at least one layer of pol urethanc foam.
  • the density of the second layer of the at least two layers of visco-elastic foam is greater than the density of the first or top layer of the at least two layers of visco- elastic foam and the density of the at least one layer of polyurethanc foam.
  • the three foam layers of the support core may include one generally planar foam layer sandwiched between two extracted foam layers, wherein each of the two extracted foam layers contains one generally planar surface and one convoluted surface opposite the generally planar surface and wherein the one convoluted surface of each of the two extracted foam layers is in contact with the one generally planar layer of the support core.
  • the mattress contains a first layer of visco-elastic foam; a second layer of polyurethane foam located beneath the first layer and a support core, located beneath the first and second layers, comprising at least three layers of foam.
  • the first layer of visco-elastic foam may be hole-punched
  • a spacer fabric may also be inserted between the first and second layers of the mattress.
  • the visco-elastic foam layer may alternatively contain three zones, a first zone proximate to the head of the mattress, a second zone proximate to the middle of the mattress and a third zone proximate to the foot of the mattress, wherein the first and third zones have a density that is less than the density of the second zone.
  • the visco- elastic layer may additionally contain one planar surface and one non-planar surface, the non- planar surface being in contact with the second layer of polyurethane foam.
  • the mattress contains at least one layer of latex foam; and a support core comprising at least two layers of non-latex foam located beneath the at least one layer of latex foam.
  • the at least one layer of latex foam has a density that is greater than the density of the support core.
  • the mattress may include additional layers of latex foam in a stacked arrangement and the support core may contain additional layers of non-latex foam.
