Definitions

  • the present invention relates generally to mattresses and, more particularly, to a multi-layer mattress, which is comprised of various foam materials.
  • a common problem associated with mattresses is that they are not customized to support the b odies o f their u sers. In fact, most m attresses are comprised o f m aterials which have the same hardness or firmness throughout the mattress.
  • customized mattresses have been provided, which have two zones of hardness or firmness. Although these mattresses are customized to meet user preferences with respect to hardness or firmness for each of the users, these mattresses are not customized to meet user preferences with respect to the different areas of the body for each of the respective users.
  • the present invention is directed to a breathable mattress including a plurality o f layers, where one of the mattress layers is further comprised of a plurality of sections and the sections are comprised of different types of materials, which have varying firmnesses and feel and which may also be comprised of material that is perforated or of an open-cell structure to allow for air circulation.
  • Figure 1 shows a perspective view of a mattress, which is partially sectioned to show a plurality of foam layers
  • Figure 2 shows a side view of the foam layers that form the mattress shown in Fig. 1
  • Figure 3 shows an exploded, perspective view of the foam layers shown in Fig. 2, without the outer mattress cover
  • Figure 4 shows a top view of the contour layer shown in Fig. 3.
  • a mattress 20 which is comprised of multiple foam layers. More particularly, as shown in Figs. 1 and 2, the mattress 20 is comprised of a comfort layer 22, a contour layer 24, an air foam layer 26, and a foam base layer 28. Although the mattress shown in Figs.
  • the comfort layer 22 is preferably positioned on the top of the mattress 20 and is comprised of material that is soft and breathable. For example, materials, including, but not limited to, convoluted latex, regular latex, viscoelastic polyurethane, regular polyurethane or convoluted polyurethane may be used.
  • the comfort layer 22 be comprised of material having an open-cell structure or being perforated for u se i n connection w ith the m attress 20, i t s hould appreciated t hat o ther materials may also be used, as long as they possess similar characteristics as the materials mentioned above.
  • the comfort layer 22 may be of a varying thicknesses, the preferred embodiment of the present invention includes a comfort layer 22 having a thickness between l and 4 inches.
  • t he c ontour 1 ayer 24 w ill i n clude a plurality of zones, where each of the zones may vary in firmness and feel.
  • the embodiment shown in Figs., 1 - 4 depicts a seven-zoned layer that utilizes a combination of viscoelastic foam, which is perforated, and conventional polyurethane foam, which may or may not be perforated. Because the viscoelastic foam is perforated and the conventional polyurethane foam is of an open-cell structure, each of these materials will allow air to circulate through the contour layer 24.
  • the air foam layer 26 may be comprised of reticulated foam, which has an open- cell structure and allows air to circulate through the air foam layer 26. Reticulated foam is strong, easily fabricated and resistant to chemicals, hi addition, reticulated foam typically has pore sizes that range from 4 to 100 pores per inch.
  • reticulated foam has been commonly used in connection with a variety of products, it has not been used in connection with mattresses. It should be understood by those with skill in the art that other materials having similar characteristics may also be used to form the air foam layer 26.
  • the air foam layer 26 may be of a varying thicknesses, the preferred embodiment of the present invention includes an air foam layer 26 having a thickness between 2 and 4 inches.
  • the foam base layer 28 is normally positioned on the bottom of the mattress 20 and comprised of material that is firmer and more supportive, such as polyurethane.
  • the foam base layer 28 may also be comprised of a material having an open-cell structure for allowing air to circulate through the foam base layer 28. It should be understood by those with skill in the art that other materials or manufacturing techniques, such as perforation, may also be employed to form the foam base layer 28 in order to achieve different firmnesses and feel and air circulation qualities. Although the foam base layer 28 may be of a varying thicknesses, the preferred embodiment of the present invention includes a foam base layer 28 having a thickness between 2 and 6 inches. For creating the mattress 20 shown in Figs. 1 and 2, the foam layers 22, 24, 26, 28 extend in a substantially parallel, horizontal direction and are stacked in vertical relation to one another.
  • each of the foam layers 22, 24, 26, 28 are substantially aligned and interface with each other on their horizontal planes.
  • Each of the foam layers 22, 24, 26 and 28 may be attached by adhesives, such as Simalfa glue.
  • the mattress 20 should be viewed as comprising a first side 21a and a second side 21b, where the first side 21a and second side 21b form substantially planar surfaces. More specifically, the first side 21a and second side 21b for the mattress also includes a top portion 20a, a bottom portion 20b, a left side 20c and a right side 20d.
  • each of the foam layers 22, 24, 26, 28 also include a first side, a second side, a top portion, a bottom portion, a left side and a right side, with reference numerals associated with each of those portions or sides that correspond to the reference numerals used to describe the same portions or sides on mattress 20.
  • the contour layer 24 includes a plurality of sections 30 that extend from the left side 24c of the contour layer 24 to the right side 24d of the contour layer 24. Also, it should be appreciated that sections 30 extend in a s ubstantially erpendicular direction as compared to the space extending between the top portion 20a and the bottom portion 20b. Moreover, each of these sections 30 may be comprised of different foam types, such as latex, viscoelastic, polyurethane and other similar materials, which may also be perforated if necessary.
  • These sections 30 may be attached to each other by adhesives, such as Simalfa glue, or by using other techniques that are well-known in the industry.
  • adhesives such as Simalfa glue
  • the benefits of using different foam types is that the contour layer 24 and the mattress 20 may include a plurality of zones associated with each of these section 30, where each of these zones possess a different firmness and feel.
  • the benefits of using materials that are either perforated or of an open-cell structure is that air will be allowed to circulate throughout t he entire m attress 20, t hereby a llowing t he m attress to p rovide a " cooler" surface and a more comfortable sleep for its users, which may also reduce tossing and turning.
  • each of the foam layers 22, 24, 26, 28 and sections 30 be comprised of materials that are perforated or of an open-cell structure, and that provide the desired firmness and feel.
  • viscoelastic is a unique open cell foam that continuously molds to the shape of an object interfacing with the viscoelastic material b ased o n t he t emperature o f t he v iscoelastic m aterial. T herefore, v iscoelastic foam gets softer as its ambient temperature rises. This is important because mattress users are known to have pressure points associated with different portions of their body.
  • latex foam also known as latex foam rubber, is known in the industry and consists of a network of open, or inner-connecting, cells, which are uniform in size and character. It is advantageous to use latex foam in connection with mattresses because latex foam is capable of molding to the shape of an object that interfaces with the latex foam, while also providing support to the object.
  • the contour layer 24 includes a plurality of zones, for each of the zones posses a different firmness and feel. Moreover, each of these zones will correlate to one of the sections 30 that form the contour layer 24.
  • Fig. 4 shows a top view of the contour layer 24, including seven sections 30, which may each be comprised of different materials.
  • one embodiment of the present invention includes a contour layer 24 that is comprised of seven sections 30a, 30b, 30c, 30d, 30e, 3 Of, 30g.
  • each of the sections are comprised of polyurethane foam or viscoelastic foam and each of those sections 30 may posses the following technical specifications. It should be understood that the density and firmness ranges provided below are only preferred and that materials with a density or firmness outside of the defined ranges may be used without departing from the teachings included herein.
  • Section 30a which may also be referred to as the head portion, may be comprised of polyurethane foam, which may be solid or perforated, having a minimum density of 1.5 lbs./cu. ft.
  • Section 30b which may also be referred to as the shoulder portion, may be comprised of viscoelastic foam having a density of between 3-5 lbs./cu. ft. and a firmness rating of between 10-20 LFD.
