  • top and bottom are used for the purpose of description and are not intended to indicate or imply relative importance, significance, unless otherwise specified.
  • the term “top” does not necessarily refer to the top most layer, and “bottom” does not necessarily refer to the bottom most layer.
  • a flippable mattress topper 102 according to an embodiment of the present invention is illustrated in Figs. 1-1B and 3 .
  • the flippable mattress topper 102 can support one or more body parts of a user, and in some embodiments is dimensioned for use upon a bed mattress to support all or substantially all of the body parts of a user.

  • a body support e.g., a mattress
  • the flippable mattress topper 102 is releasably secured to the body support, such as by hook and loop fastener material, zippers, snaps, and other conventional fasteners, or in any other suitable manner.
  • the flippable mattress topper 102 includes a core 106 and a cover 114 encasing the core 106.
  • the cover 114 is comprised of different materials having different thermal properties on opposite sides (i.e., top and bottom sides) of the cover 114.
  • the core 106 of the topper 102 can have any number of layers of material, such as first and second layers 110, 112 shown in the embodiment of Figs. 1-1 B and 3.
  • the core 106 of the mattress topper 102 can have any thickness desired, and as described above, can be defined by any number of layers of material.
  • the cores 106 in the illustrated embodiments are each approximately 7cm in thickness.
  • core thicknesses of no less than about 5cm and/or no greater than about 9cm can be used.
  • core thicknesses of no less than about 3cm and/or no greater than about 11cm can instead be used.

  • Each of the first and second layers 110, 112 can be substantially flat bodies having substantially planar top (first) and bottom (second) surfaces 116, 118, 120, 122 as shown in Fig. 1 .
  • the core 106 shown in Figs. 1-1B and 3 is a substantially flat body having substantially planar top (first) and bottom (second) surfaces positioned opposite one another.
  • one or more of the top and bottom surfaces 116, 118, 120, 122 of either or both first and second layers 110, 112 can be non-planar, including without limitation surfaces having ribs, bumps, and other protrusions of any shape and size, surfaces having grooves, dimples, and other apertures that extend partially or fully through the respective layer, and the like.
  • either or both of the first and second layers 110, 112 can have shapes that are not flat.
  • either or both layers 110, 112 can be generally wedge-shaped, can have a concave or convex cross-sectional shape, can have a combination of convex and concave shapes, can have a stepped, faceted, or other shape, can have a complex or irregular shape, and/or can have any other shape desired.
  • any or all of the layers defining the core 106 of the flippable mattress topper 102 can comprise visco-elastic foam (sometimes referred to as "memory foam” or "low resilience foam”).
  • the first and second layers 110, 112 in the illustrated embodiment of Figs. 1-1 Band 3 are formed of visco-elastic foam.
  • the visco-elastic foam layers are interchangeable or replaceable, thereby varying characteristics (e.g., hardness, density, porosity, and the like) of the flippable mattress topper 102.
  • the first and second layers 110, 112 can provide relatively soft and comfortable surfaces for the user's body. Coupled with the slow recovery characteristic of the visco-elastic foam, the layers 110, 112 can also conform to a user's body, thereby distributing the force applied by the user's body upon the layers 110, 112.
  • the core 106 (i.e., the layers 110, 112) can have a density providing a relatively high degree of material durability. Also, the density of the visco-elastic foam in the layers 110, 112 can also impact other characteristics of the visco-elastic foam, such as the manner in which the core 106 responds to pressure, and the feel of the foam.
  • the visco-elastic foam(s) of the core 106 can be selected for responsiveness to any range of temperatures.
  • a temperature responsiveness in a range of a user's body temperatures can provide significant advantages.
  • a visco-elastic foam is considered "responsive" to temperature changes if the visco-elastic foam exhibits a change in hardness of at least 10% measured by ISO Standard 3386 through the range of temperatures between 10 and 30 degrees Celsius.
  • the core 106 (and in particular at least one of the layers 110, 112), comprises a cellular structure of flexible visco-elastic polyurethane foam in which the cells of the visco-elastic foam are essentially skeletal structures.
  • This "reticulated" foam can be visco-elastic or non-visco-elastic.
  • the cells of reticulated foam are each defined by a plurality of apertured windows surrounded by cell struts. The cell windows of reticulated foam can be entirely gone (leaving only the cell struts) or substantially gone.
  • the foam is considered "reticulated” if at least 50% of the windows of the cells are missing (i.e., windows having apertures therethrough, or windows that are completely missing and therefore leaving only the cell struts).
  • windows of the cells are missing (i.e., windows having apertures therethrough, or windows that are completely missing and therefore leaving only the cell struts).
  • Such structures can be created by destruction or other removal of cell window material, or preventing the complete formation of cell windows during the manufacturing process of the foam.
  • the reticulated visco-elastic foam is capable of providing some degree of support or responsiveness that is substantially independent of temperatures experienced by the first layer 110. Therefore, the core 106 can comprise reticulated visco-elastic foam that is substantially insensitive to temperature changes within a range of between about 10°C and about 35°C. As used herein, a visco-elastic foam is "substantially insensitive" to temperature changes if the visco-elastic foam exhibits a change in hardness of less than 10% measured by ISO Standard 3386 through the range of temperatures between 10 and 30 degrees Celsius.
  • the reticulation of visco-elastic foam can increase the porosity, thermal conductivity, and thermal diffusivity of the core 106, which can enable significantly higher airflow into, out of, and through at least the layers comprising the reticulated visco-elastic foam (e.g., the second layer 112 in the illustrated embodiment of Figs. 1-1B and 3 ). Also, in those embodiments in which one or more layers 110, 112 of the core 106 comprise reticulated foam (whether visco-elastic or otherwise), such foam can function as a wick, drawing moisture from a user thereon or from the area around the user into the flippable mattress topper 102 and away from the user.
  • the flippable mattress topper 102 can have a visco-elastic or non-visco-elastic foam layer (110 or 112) that is reticulated, and another (112 or 110) that is not, thereby providing different temperature and moisture wicking characteristics of the flippable mattress topper 102 on opposite sides of the flippable mattress topper 102.
  • a layer 110 of visco-elastic material closest to the user on one side of the flippable mattress topper 102 can be non-reticulated, whereas another layer of visco-elastic foam on an opposite side of the flippable mattress topper 102 can be reticulated.
  • a user resting on the first side (for example, the first layer 110) can feel warmer than the a user resting on an opposite side (for example, the second layer 112) based upon the enhanced heat transport and moisture wicking properties of the reticulated foam.
  • Such a flippable mattress topper 102 can be oriented with either side facing upward (to face a user resting thereon) based upon the desired heating or cooling desired by the user at any given time.
  • one or more layers of the core 106 can comprise reticulated visco-elastic foam as just described, in some embodiments the core 106 instead or also has one or more layers of reticulated non-visco-elastic foam. Also, in some embodiments, one or more layers of reticulated or non-reticulated visco-elastic foam are used in conjunction with one or more layers of non-viscoelastic foam, such as polyurethane foam, any expanded polymer (e.g., expanded ethylene vinyl acetate, polypropylene, polystyrene, or polyethylene), latex foam, and the like. Such combinations of foam layers can provide a desirable combination of user comfort and support.
  • the layer(s) of the core 106 have other types of polyurethane, latex, or other foam.
  • a cover 114 encases the core 106 and provides different thermal properties for the flippable mattress topper 102 on opposite sides of the topper 102. Additionally, the cover 114 can provide protection for the core 106 located therein.
  • the cover 114 includes a first cover portion 126 and a second cover portion 130 positioned opposite the first cover portion 126. The first cover portion 126 is positioned adjacent the first surface of the core 106 (i.e., the top surface 116 of the first layer 110) and the second cover portion 130 is positioned adjacent the second surface of the core 106 (i.e., the bottom surface 122 of the second layer 112).
  • first cover portion 126 is secured to (e.g., stitched) and/or integrally formed with the second cover portion 130.
  • first and second cover portions 126, 130 are releasably secured to one another by hook and loop fastener material, zippers, snaps, and other conventional fasteners, or in any other suitable manner.
  • the first cover portion 126 is formed of a first material that is relatively warm to the touch or initial contact, and that in some embodiments has thermally insulative properties. Examples of such materials include, without limitation, cotton, flannel, fleece, wool, and the like, and can include any type of wicking material capable of moisture and heat transport as described in greater detail below.
  • the second cover portion 130 is formed of a second material that is relatively cool to the touch or initial contact, and that in some embodiments has thermally conductive properties. Examples of such materials include, without limitation, satin, silk, and the like.
  • the first and second materials have various characteristics and/or properties that can determine the degree of warming and cooling, respectively, transmitted to and sensed by a user. Examples of the various characteristics and properties of the first and second materials include texture, thermal properties, density and permeability.

  • the user can sense the smoothness or roughness thereof. The degree of smoothness can determine how well a user's body is warmed and/or cooled by the cover portion 126, 130.
  • a smoother cover portion can feel cooler to body contact than a rougher cover portion.
  • the thread count of the material can at least partially determines the smoothness of the cover portions (i.e., a larger number of threads per unit of surface area resulting in a rougher surface than a smaller number of threads per unit of surface area).
  • the first cover portion 126 comprises a smoother material than the second cover portion 130.
  • Thermal conductivity can at least partially determine whether a cover portion 126, 130 of the cover 114 feels warmer or cooler to a user.
  • the thermal conductivity of the respective cover portions 126, 130 can at least partially determine the side or surface of the flippable mattress topper 102 that warms and cools the user.
  • the first cover portion 126 can be more insulative to a user by having a low thermal conductivity, which results in the first material feeling warmer against the user's body.
  • the first cover portion 126 can resist the flow of heat from a user's body, and can reduce the flow and effect of ambient fluid (e.g., air) on the user's body - on the temperature of the user's body, in particular.
  • ambient fluid e.g., air
  • the second cover portion 130 can be less insulative to a user by having a higher thermal conductivity than the first cover portion 126, which results in the second material feeling cooler against the user's body.
  • the second material of the second cover portion 130 can more easily transfer heat from a user's body, and can increase the flow and effect of ambient fluid (e.g., air) on the user's body to cool the user's body.
  • the first cover portion 126 of the cover 114 has a density higher than that of the second cover portion 130.
  • the different densities of the cover portions 126, 130 can provide different porosities of the cover portions 126, 130.

  • the second material can allow fluid (e.g., moisture, air, and the like) and heat to flow therethrough more so than the first material in order to help cool the user's body.
  • the second material can therefore function as a wick to draw moisture from a user's body thereon and from a region around the user's body into the core 106, and can perform this function to a greater extent than the first material, thereby providing the user with a greater cooling sensation than the first material.
  • the porosity of these materials is substantially independent of the density of the materials.
  • the first material can have the same porosity with either a low density or a high density.
  • the degree of permeability or breathability (i.e., permeable, semi-permeable) of the cover 114 can at least partially determine the feel of the cover sensed by the user, and can affect the warming and/or cooling capabilities of the flippable mattress topper 102.
