BODY SUPPORT ARTICLE COVER CONTAINING SEGMENTS FROM STITCHING OR QUILTING AND HAVING GEL-TYPE STRUCTURES INTEGRATED WITH FOAM

FIELD OF THE INVENTION

Generally, the present disclosure relates to utilizing a gel material integrated with foam in a body support article, such as mattresses covers, mattress topper covers, cushions covers, pillows covers, and the like.

DESCRIPTION OF THE RELATED ART

Foam body support articles, e.g., pillows, cushions, mattress toppers, and mattresses, such as viscoelastic or so-called “memory foam” mattresses, provide desirably high levels of firmness and support for many users. However, mattresses comprising only viscoelastic foam may lack sufficient support for some users. Also, mattresses comprising only one particular type of foam may lack desired levels of support for certain regions of a user's body. Further, foam mattresses are often reputed to “sleep hot,” i.e., inadequately dissipate the user's body heat.

Attempts to resolve these issues include the use of mattress toppers, including toppers comprising gel bodies embedded in a suitable material and/or bonded to upper and/or lower fabric layers. However, existing gel toppers provide uniform support to all users of a mattress, and thus, if the partners sharing a mattress have different support preferences, one of the partners may be dissatisfied by a mattress topper providing support preferred by the other, or both partners may be dissatisfied if, in an effort to compromise, they select a mattress topper that is “neither fish nor fowl,” providing too little support for one and too much support for the other.

“Sleeping hot” is commonly addressed by the inclusion of phase change materials (PCMs) which absorb heat as part of a transition between their solid and liquid forms or between crystal structures thereof. However, once the phase change is complete, the material has little additional capacity to absorb heat from the user. Accordingly, the relief provided by PCMs is short-lived, generally lasting far less than 6-8 hours.

The present disclosure may address and/or at least reduce one or more of the problems identified above.

SUMMARY OF THE INVENTION

The following presents a simplified summary of the disclosure in order to provide a basic understanding of some aspects of the disclosure. This summary is not an exhaustive overview of the disclosure. It is not intended to identify key or critical elements of the disclosure, or to delineate the scope of the disclosure.

DETAILED DESCRIPTION

Various illustrative embodiments of the disclosure are described below. In the interest of clarity, not all features of an actual implementation are described in this specification. It will, of course, be appreciated that, in the development of any such actual embodiment, numerous implementation-specific decisions must be made to achieve the developers' specific goals, such as compliance with system-related and business-related constraints, which will vary from one implementation to another. Moreover, it would be appreciated that such a development effort might be complex and time-consuming but would be a routine undertaking for those of ordinary skill in the art having the benefit of this disclosure.

The present subject matter will now be described with reference to the attached figures. Various structures, systems and devices are schematically depicted in the drawings for purposes of explanation only and to not obscure the present disclosure with details that are well known to those skilled in the art. Nevertheless, the attached drawings are included to describe and explain illustrative examples of the present disclosure. The words and phrases used herein should be understood and interpreted to have a meaning consistent with the understanding of those words and phrases by those skilled in the relevant art. No special definition of a term or phrase, i.e., a definition that is different from the ordinary and customary meaning as understood by those skilled in the art, is intended to be implied by consistent usage of the term or phrase herein. To the extent that a term or phrase is intended to have a special meaning, i.e., a meaning other than that understood by skilled artisans, such a special definition will be expressly set forth in the specification in a definitional manner that directly and unequivocally provides the special definition for the term or phrase.

Embodiments herein are directed to body support articles, wherein the body support articles have improved user experience, such as support for multiple users having different support preferences and/or improved comfort for users who tend to sleep hot. Body support articles include, but are not limited to, mattresses, pillows, mattress toppers, cushions, etc.

In one embodiment, each of the quilted or isolated portion may house a gel layer integrated (e.g., affixed, coupled, glued, operatively coupled, etc.) with a foam or a foam-type material.

In yet another embodiment, the gel layer may be a dual sided gel layer where one side has a first gel layer configuration and the other side has a second gel layer configuration (e.g., with different geometrical gel support shapes, firmness, spacing between empty spaces between gel support elements, etc.). In another embodiment, each of the quilted or isolated portions may house a dual sided gel layer that is affixed onto a foam layer.

FIG. 1A illustrates a stylized top view of a gel layer 100, in accordance with embodiments herein. FIG. 1B illustrates a stylized nearsighted side cross-sectional view of the gel layer 100 along line A-A′. By “nearsighted” it is meant that elements of the gel layer 100 disposed behind the line A-A′ are omitted, e.g., a first gel segment 120f, as will be discussed in more detail below.

The gel layer 100 comprises a first gel lattice 110 having a rectangular prism shape having a first gel lattice height 111, a first gel lattice width 112, and a first gel lattice length 113. The “width” and the “length” may be arbitrarily selected, each from an opposed pair of sides of the rectangular prism. Typically, and particularly for embodiments wherein the gel layer 100 is intended to top at least about half of a body support article, the width and height may be selected such that the first gel lattice width 112 is less than the first gel lattice length 113.

Regardless of how the width and height are assigned, the first gel lattice height 111 is no more than one-third of the shorter of the first gel lattice width 112 and the first gel lattice length 113. In other words, the first gel lattice 110 is much shorter than it is long and wide.

In embodiments, the first gel lattice height 111 may be from about 0.25″ (0.64 cm) to about 2″ (5.08 cm).

In some embodiments, the gel segments 120 may represent collectively a gel layer that may be implemented into a body support article. In an alternative embodiment, the gel segments may be individual gel components that are isolated (e.g., by quilting, sewing, etc.) into separate sections for a body support article cover (e.g., a mattress cover, a pillow cover, a cushion cover, etc.). For example, the dotted lines 172 may represent quilt or sewing lines in the vertical direction, while the dotted lines 174 may represent quilt or sewing lines in the horizontal lines. In this manner the intersections of lines 172 and 174 may represent separate sections of the body support article cover.

“Gel” is a term well-known in the art. More information regarding gel formulations and manufacturing techniques can be found in patents and other literature incorporated herein by reference.

In one embodiment, the first gel lattice 110 may comprise the following components by weight: Styrene block copolymer 2-80%, plasticized oil 10-90%, thermoplastic polystyrene-polybutadiene-polystyrene block copolymer 5-80%, toner 0.03-3%.

In a further embodiment, the first gel lattice 110 may comprise an essential oil additive from 0.01%-5% by weight. In one embodiment, the essential oil component of the essential oil additive is selected from the group consisting of green tea oil, sweet orange oil, menthol oil, peppermint oil, cedarwood oil, lemon oil, eucalyptus oil, aromatic litsea/mountain pepper oil, clove oil, spearmint oil, rose oil, lemongrass oil, lavender oil, thyme oil, alfalfa oil, allspice oil, ambrette (seed) oil, angelica root oil, angelica seed oil, angelica stem oil, angostura (cusparia bark) oil, anise oil, asafetida-foetida oil, balm (lemon balm) oil, balsam of peru oil, basil oil, bay leaves oil, bay (myrcia oil) oil, bergamot (bergamot orange) oil, bitter almond oil, bois de rose oil, cacao oil, camomile (chamomile) flowers oil, cananga oil, capsicum oil, caraway oil, cardamom seed (cardamon) oil, carob bean oil, carrot oil, cascarilla bark oil, cassia bark oil, chinese oil, cassia bark oil, padang or batavia oil, cassia bark oil, saigon oil, celery seed oil, cherry oil, wild oil, bark oil, chervil oil, chicory oil, cinnamon bark oil, ceylon oil, cinnamon bark oil, chinese oil, cinnamon bark oil, saigon oil, cinnamon leaf oil, ceylon oil, cinnamon leaf oil, chinese oil, cinnamon leaf oil, saigon oil, citronella oil, citrus peels oil, clary (clary sage) oil, clover oil, coca (decocainized) oil, coffee oil, cola nut oil, coriander oil, cumin (cummin) oil, curacao orange peel (orange oil, bit oil, cusparia bark oil, dandelion oil, dandelion root oil, dog grass (quackgrass oil, triticum) oil, elder flowers oil, estragole (esdragol oil, esdragon oil, t oil, estragon (tarragon) oil, fennel oil, sweet oil, fenugreek-gr oil, galanga (galangal) oil, geranium oil, geranium oil, east indian oil, geranium oil, rose oil, ginger oil, grapefruit oil, guava oil, hickory bark oil, horehound (hoarhound) oil, hops oil, horsemint oil, hyssop oil, immortelle oil, jasmine oil, juniper (berries) oil, kola nut oil, laurel berries oil, laurel leaves oil, lavender oil, lavender oil, spike oil, lavandin oil, lemon (l.) burm. oil, lemon balm oil, lemongrass oil, lemon peel (l.) oil, lime oil, linden flowers oil, locust bean oil, oil, lupulin oil, mace oil, mandarin oil, marjoram oil, sweet oil, yerba mate oil, melissa (see balm) oil, menthol oil, menthyl acetate oil, molasses (extract) oil, mustard oil, naringin oil, neroli oil, bigarade oil, nutmeg oil, onion oil, orange oil, bitter oil, flowers oil, orange oil, bitter oil, peel oil, orange leaf (l.) oil, orange oil, sweet oil, orange oil, sweet oil, flowers oil, orange oil, sweet oil, peel oil, origanum oil, palmarosa oil, paprika oil, parsley (mi oil, pepper oil, black oil, pepper oil, white oil, peppermint oil, peruvian balsam oil, petitgrain oil, petitgrain lemon oil, petitgrain mandarin or tangerine oil, pimenta oil, pimenta leaf oil, pipsissewa leaves oil, pomegranate oil, prickly ash bark oil, rose absolute oil, rose (otto of roses oil, attar of roses) oil, rose buds oil, rose flowers oil, rose fruit (hips) oil, rose geranium oil, rose leaves oil, rosemary oil, saffron oil, sage oil, sage oil, greek oil, sage oil, spanish oil, st. john's bread oil, savory oil, summer oil, savory oil, winter oil, schinus molle oil, sloe berries (blackthorn berries) oil, spearmint oil, spike lavender oil, tamarind oil, tangerine oil, tarragon oil, tea oil, thyme oil, thyme oil, white oil, thyme oil, wild or creeping oil, tuberose oil, turmeric oil, vanilla oil, violet flowers oil, violet leaves oil, violet leaves absolute oil, wild cherry bark oil, ylang-ylang oil, and zedoary bark oil.

In one embodiment, the essential oil is green tea oil, which may be present at 0.3 wt %.

The first gel lattice 110 comprises a plurality of first gel segments, collectively and/or generically 120, with individual first gel segments 120a, 120b, 120c, 120d, 120e, 120f, and 120g specifically identified in FIG. 1A and FIG. 1B. The definition of “segments” is arbitrary, in that the first gel lattice 110 is essentially integral. Generally, each first gel segment 120 has a first segment height 122 essentially equal to the first gel lattice height 111, and a first segment thickness 121 less than the first segment height 122.

The first gel segments 120 define a plurality of first gaps, collectively and/or generically 130, with individual first gaps 130-1 and 130-2 specifically identified in FIG. 1A and FIG. 1B. In FIG. 1A and FIG. 1B, the first gap 130-1 is defined by first gel segments 120a, 120b, 120c, and 120d. The first gap 130-2 is defined by first gel segments 120e, 120f, and 120g, along with a perimeter segment 144 to be described later.

Accordingly, a “segment” may be considered as a portion of the first gel lattice 110 that separates any two adjacent first gaps 130. Each first gap 130 has a first size and a first shape. The shape is defined herein by reference to two-dimensional figures as seen from a top view. For example, the first gaps 130 depicted in FIG. 1A, e.g., first gaps 130-1 and 130-2 each have a square shape. The size of the first gaps 130 may also be varied, with “size” here referring to the lengths of the gel segments 120 defining each first gap 130 and the surface area of the shape.

The square shape of the first gaps 130 in FIG. 1A is merely exemplary. Any one or more of a wide range of shapes may be considered. In one embodiment, the first gaps 130 may each have a first size and a first shape selected from the group consisting of squares, rectangles, diamonds, parallelograms, other quadrilaterals, triangles, polygons with other than four sides, circles, ellipses, raindrops, and other curved shapes.

FIG. 1C illustrates a stylized cross-sectional view of one segment or portion of a quilted layer, in accordance with a first embodiment herein. The structure inside the vertical quilt or sewing lines 174 and the horizontal quilt of sewing lines 172 may be a segment or portion of the quilted body support article cover. Those skilled in the art would appreciate that other patterns of quilting or sewing may be performed to create different shaped sections or portions of the quilted layer. In other embodiments, instead of quilting or sewing, other types of segment isolation may be achieved, e.g., using adhesives, lasers, etc.

The example of FIG. 1C illustrates, in cross-section, shows that the structure in each section may contain a gel segment 120 over which a top cover is positioned. Under the gel segment, a bottom cover is positioned. The gel segment 120 is isolated from other similar sections by the quilt/sewing/affixation lines 172, 174.

FIG. 1D illustrates a stylized cross-sectional view of one segment of a quilted layer, in accordance with a second embodiment herein. Similar to the example of FIG. 1C, the quilt/sewing/affixation lines 172, 174 isolates a plurality of sections. The section of FIG. 1D may comprise a gel layer that has two portions, i.e., a dual gel layer segment. The gel layer may comprise a 1s t gel structure 120a and a 2n d gel structure to form a dual layer gel segment. The 1s t gel structure 120 may vary in one or more features, such as firmness, geometric shapes of the gel structures, spacing between the components of the gel structure, etc. In this manner, different feel, sensation, coolness, firmness, support, etc., may be realized based on which side the body support article cover is nearest to the user of a body support article. In some embodiments, the segment between the lines 172, 174 may be allowed to move about between those lines, or alternatively, may be affixed within the segment.

FIG. 1E illustrates a stylized cross-sectional view of one segment of a quilted layer, in accordance with a third embodiment herein. Similar to the examples of FIGS. 1C and 1D, the quilt/sewing/affixation lines 172, 174 isolates a plurality of sections. The section of FIG. 1E may comprise a gel layer that is affixed to foam layer 186. The foam layer 186 may be similar to other foam layers described herein. In this manner, each segment of the quilted/sewn portion contains a gel layer and a foam layer. Those skilled in the art would appreciate that the gel layer 120 may be on top of the foam layer 186 or vice versa.

FIG. 1F illustrates a stylized cross-sectional view of one segment of a quilted layer, in accordance with a fourth embodiment herein. Similar to the examples of FIG. 1C-1E, the quilt/sewing/affixation lines 172, 174 isolates a plurality of sections. The section of FIG. 1F may comprise a gel layer that has two portions, i.e., a dual gel layer segment. The gel layer may comprise a 1s t gel structure 120a and a 2n d gel structure to form a dual layer gel segment. The 1s t gel structure 120 may vary in one or more features, such as firmness, geometric shapes of the gel structures, spacing between the components of the gel structure, etc. In this manner, different feel, sensation, coolness, firmness, support, etc., may be realized based on which side the body support article cover is nearest to the user of a body support article.

The section of FIG. 1F may comprise a dual sided gel layer that is affixed to foam layer 186. The foam layer 186 may be similar to other foam layers described herein. In this manner, each segment of the quilted/sewn portion contains a dual sided gel layer and a foam layer. Those skilled in the art would appreciate that the dual sided gel layer may be on top of the foam layer 186 or vice versa.

FIG. 3A-FIG. 3K show particular top views of individual first gaps 130 that may be used in the gel layer 100 or 200. In one embodiment, each first gap 130 has a shape in top view selected from the group consisting of squares, rectangles, diamonds, parallelograms, other quadrilaterals, triangles, polygons with other than four sides, circles, ellipses, raindrops, and other curved shapes. For example, in FIG. 3A, the first gap 130 has a square shape in top view, with the understanding the square is oriented such that all of the gel segments 120 are parallel to a side of the gel lattice. In FIG. 3B, the first gap 130 has a rectangular shape in top view. In FIG. 3C, the first gap 130 has a square shape in top view, with the understanding the square is oriented such that none of the gel segments 120 are parallel to any side of the gel lattice. In FIG. 3D, the first gap 130 has a parallelogram shape in top view. In FIG. 3E, the first gap 130 has a triangular shape in top view. In FIG. 3F, the first gap 130 has a hexagonal shape in top view. In FIG. 3G, the first gap 130 has a circular shape in top view. In FIG. 3H, the first gap 130 has an elliptical shape in top view. In FIG. 3I, the first gap 130 has a raindrop shape in top view.

In FIG. 3J, the gap 130 has a diamond shape in top view. By “diamond” herein it is meant a quadrilateral defined by four gel segments 120, wherein each of the gel segments 120 has the same length. The four gel segments 120 define four corners, each with an interior vertex angle α or β, with vertex angles α being at a first pair of opposed corners and vertex angles β being at a second pair of opposed corners. Generally, α is less than 90° and β is more than 90°, with the proviso that α+β=180°. In one embodiment, α is from 45° to 85° and β is from 95° to 135°.

Though not to be bound by theory, we have observed that a first gel lattice 110 comprising diamond-shaped first gaps 130 tends to be plush, i.e., is relatively not firm. It also tends to have greater strength at the joints between first gel segments 120 than square-shaped gaps, i.e., first gel segments 120 are less likely to tear or otherwise suffer damage at joints when the first gaps 130 are diamond-shaped.

In FIG. 3K, the gap 130-3 has a convex pentagon shape that is neither equilateral nor equiangular. In the specific embodiment shown in FIG. 3K, the convex pentagon shape is defined by two consecutive first gel segments 324a, 324b, each having a length equal to a first length, and three consecutive first gel segments 325a, 325b, and 325c, each having a length equal to a second length less than the first length.

One property of interest of the convex pentagon shape that is neither equilateral nor equiangular is shown in FIG. 3L. In FIG. 3L, six of the convex pentagon shapes 130-3 form a rosette 360 with 6-fold rotational symmetry around a vertex of the two consecutive first gel segments having the first length. The precise values of the first length and the second length may be selected such that the rosette 360 may tile the first gel lattice 110. Such tiling is shown in FIG. 9, FIG. 10, FIG. 14, FIG. 15, and FIG. 21.

Though not to be bound by theory, we have observed that a first gel lattice 110 comprising first gaps 130 with a convex pentagon shape that is neither equilateral nor equiangular, with the first gaps 130 arranged in rosettes 360 tiling the first gel lattice 110, are relatively firm while providing improved pressure relief relative to first gaps 130 with hexagonal shapes.

Accordingly, in one embodiment of the first gel lattice 110, all the first gaps 130 have an identical shape selected from diamonds and convex pentagons that is neither equilateral nor equiangular.

Although FIG. 1A and FIG. 1B depict all first gaps 130 as having the same square shape, in other embodiments, the plurality of first gaps 130 may comprise gaps 130 of two or more shapes. Generally, one, two, or more shapes may be chosen to give the first gel lattice 110 a tiled appearance (i.e., the gaps 130 substantially fill a top view such as FIG. 1A without overlaps or omitted spaces).

Typically, one, two, or more shapes may form a single tiling pattern, such as is shown in FIG. 1A and FIG. 9-FIG. 21, but in other embodiments, not shown, the shapes may be varied at different regions of the top surface of the first gel lattice 110.

The person of ordinary skill in the art will bear in mind that referring to the shapes of the first gaps 130 with geometric terms represents an idealization. In practice, the first gaps 130 may essentially or substantially have a given shape, bearing in mind routine processing variations, minimal processing defects, and other factors that will be apparent to the person of ordinary skill in the art having the benefit of the present disclosure. FIG. 9 through FIG. 21 present images of physical instances of gel layers, in which real-world imperfections are apparent, but in which diamond shapes and convex pentagon shapes that are neither equilateral nor equiangular are unequivocally present.

The first gel lattice 110 has a first firmness in a direction parallel to the first gel lattice height, i.e., substantially in the line of sight of the reader looking at FIG. 1A. Though not to be bound by theory, the value of the first firmness may vary depending on one or more of the formulation of the gel in the first gel lattice 110, the height 111 of the first gel lattice, the thickness 121 of the first gel segments 120, and the shape of the first gaps 130, among other structural properties that will be apparent to the person of ordinary skill in the art having the benefit of the present disclosure. The first firmness may be of a first predetermined firmness that relates to a predetermined amount of stress compression upon a weight or stress is placed on the first gel segments 120. For example, the amount of compression allowable to define a particular predetermined firmness may be set using a scale of 1 through 10, wherein “1” refers to a large amount of allowable stress compression, and progressively decreasing wherein “10” refers to a larger amount of allowable stress compression. These numbers, i.e., may be referred to as “compression factors” or “stress compression factors.” The compression factors may define the firmness of the body support articles. For example, the compression factors associated with “1” may relate to a much softer body support article having much less firmness as compared to the compression factor associated with “10,” which may relate to a much firmer body support article having much greater firmness.

In some embodiments, the stress compression may be defined by a compression strength or compressive strength. In some embodiments, Compression strength or compressive strength as used herein may relate to an amount of compression that a material may subjected to while maintain at least a portion of the integrity of the material without completely collapsing. In this manner, a higher compression or compressive strength may relate correspondingly to higher firmness of the material when stress is placed on that material. As such, the firmness of the body support article may be influenced by the varying stress compression or compression factors provided herein.

The first firmness does not necessarily have the same value at all points on the top surface of the first gel lattice 110. Variation in shape and size of first gaps 130 in one or more regions of the first gel lattice 110 may be chosen to provide regions of the first gel lattice 110 having slightly greater or slightly lesser firmness than other regions. When we use the term “a firmness” of the first gel lattice 110 or another structure, we refer to a surface-area weighted average of the precise firmness of all regions of the structure.

The gel layer 100 shown in FIG. 1A and FIG. 1B further comprises four first perimeter segments 141, 142, 143, and 144. Each first perimeter segment 141-144 has a first perimeter segment height essentially equal to the first gel lattice height 111, and a first perimeter segment thickness 145 equal to or greater than the first gel segment thickness 121. As can most readily be seen in FIG. 1A, each first perimeter segment 141-144 is essentially coincident with one and only side of the first gel lattice 110 perpendicular to the direction parallel to the first gel lattice height.

Though not to be bound by theory, perimeter segments 141-144 may increase edge strength of the first gel lattice 110, thereby reducing buckling of the first gel lattice 110 around the perimeter and maintaining a desired level of firmness.

Turning to FIG. 2, a nearsighted side view of a gel layer 200 is shown. FIG. 2 shows numerous elements identical to those shown in FIG. 1A and FIG. 1B. FIG. 2 also shows numerous elements similar to those shown in FIG. 1A and FIG. 1B. Typically, such similar elements will be identified by reference numerals having common ones and tens digits and differing by a “1” or a “2” hundreds digit. For example, FIG. 2 shows the first gel lattice 110 and a second gel lattice 210. The second gel lattice 210 comprises second gel segments 220, similar to first gel segments 120. For the sake of brevity, identical and similar elements will not be described again, and description of elements of FIG. 2 will focus on differences and new aspects relative to those shown and described regarding FIG. 1A and FIG. 1B.

As mentioned above, the gel layer 200 comprises a second gel lattice 210. The second gel lattice 210 may comprise any gel, such as the gel formulation set forth above.

The second gel lattice 210 has a second gel lattice height 211, which may but need not be equal or essentially equal to the first gel lattice height 111. The second gel lattice 210 comprises second gel segments 220, e.g., second gel segments 220h and 220i, which define a plurality of second gaps, e.g., 230-3. The second gaps 230 can be as described above. The second gel lattice 210 has a second firmness in a direction parallel to the second gel lattice height 211.

In one embodiment, the first gel lattice width 112 is essentially equal to the second gel lattice width, and the first gel lattice length 113 is essentially equal to the second gel lattice length 213.

The second gaps 230 may have any shape(s) and size(s) described above. Desirably, the second gaps 230 are generally different in shape(s) and/or size(s) than the first gaps 130. Though not to be bound by theory, different shape(s) and/or size(s) may impart a number of desirable properties to the gel layer 200.

First, the first gel lattice 110 and the second gel lattice 210 will tend to have different firmnesses, such that the firmness of the gel layer 200 perceived by a user will heavily depend on which of the first gel lattice 110 and the second gel lattice 210 is uppermost, i.e., is closest to a user's body when seated or reclined on a body support article comprising the gel layer 200 as an uppermost layer. The gel layer 200 may conveniently provide a choice of firmnesses by arranging one or the other of the first gel lattice 110 and the second gel lattice 210 as an uppermost layer. This may be done in manufacturing or, if the gel layer 200 and a body support article comprising it are so configured, by the user.

A second desirable property is that one or more first spaces 130 may be continuous with one or more second spaces 230. This may allow improved air flow and/or heat dissipation from the user's body, thereby reducing the user's perception or reality of “sleeping hot.”

In a particular embodiment, in the gel layer 200, each of the plurality of first gaps 130 may have a diamond shape; and each of the plurality of second gaps 230 may have a convex pentagon shape that is neither equilateral nor equiangular. The firmness of the first gel lattice 110 may be less than the firmness of the second gel lattice 210.

The gel layer 200 may comprise four layer perimeter segments, each layer perimeter segment having a layer perimeter segment height essentially equal to the sum of the first gel lattice height and the second gel lattice height, and a layer perimeter segment thickness greater than greater of the first gel segment thickness and the second gel segment thickness, with each layer perimeter segment being essentially coincident with the union of one and only side of the first gel lattice perpendicular to the direction parallel to the first gel lattice height and one and only side of the second gel lattice perpendicular to the direction parallel to the second gel lattice height.

In the gel layer 200, all of the first gel lattice 110, the second gel lattice 210, and all lattice and layer perimeter segments may comprise a common gel formulation, such as that described above. In one embodiment, the common gel formulation comprises by weight: Styrene block copolymer 2-80%, plasticized oil 10-90%, thermoplastic polystyrene-polybutadiene-polystyrene block copolymer 5-80%, and green tea oil 0.3%.

Turning to FIG. 4 and FIG. 5, a stylized nearsighted side cross-sectional view of a body support article 400 or 500, in accordance with embodiments herein, is illustrated. The body support article 400 or 500 may have a generally rectangular profile in top view (not shown). For example, the body support article 400 or 500 may be a mattress.

FIG. 6A shows a top view of a body support article 600. FIG. 4-FIG. 6A have much in common and will generally be described together.

As shown in FIG. 4, FIG. 5, and FIG. 6A, the body support article 400 or 500 may comprise a support layer 450 having a rectangular prism shape having a support layer width 452 and a support layer length 453, and gel layer 100 or 200 above the support layer 450.

The support layer 450 may comprise any appropriate material. The material may be a polymeric material, such as polyurethane; a viscoelastic material; a non-viscoelastic material; an elastomeric material; a gel; any material disclosed by any document incorporated herein by reference; or the like.

The gel layer 100 or 200 is as described above.

In one embodiment, as depicted in FIG. 6A, the support layer width 452 is essentially equal to the sum of the first gel lattice width 112 and the second gel lattice width 212, and body support article comprises two instances of the gel layer, e.g., first instance a of gel layer 200 (reference numeral 200a) and second instance b of gel layer 200 (reference numeral 200b), wherein the first instance 200a of the gel layer 200 is positioned on and aligned with a left half of the support layer 450 and a second instance 200b of the gel layer 200 is positioned on and aligned with a right half of the support layer 450. As is customary in the body support article arts, “left” and “right” refer to halves of a top surface of the body support article 600 or a layer thereof as seen by the person of ordinary skill in the art standing at the foot of a piece of furniture comprising the body support article 600. For most body support articles, “left” and “right” are arbitrary, as in either half of the top surface of the body support article may be left or right, unless the body support article is constructed such that one end is intended for supporting a user's head and upper torso and the opposite end is intended for supporting the user's lower legs and feet.

In FIG. 6A, the first instance 200a of the gel layer is positioned with the first gel lattice 110 uppermost. In the first instance 200a, the first spaces 130 have first shapes, e.g., square shapes in the depicted embodiment. The second instance 200b of the gel layer is positioned with the second gel lattice 210 uppermost. In the second instance 200b, the second spaces 230 have second shapes, e.g., circular shapes in the depicted embodiment. Of course, in view of the above discussion of first spaces 130 and second spaces 230, the person of ordinary skill in the art will understand that the first spaces 130 and the second spaces 230 may have any shape.

By having different shapes 130, 230 in their uppermost gel lattices 110, 210, the first instance 200a and the second instance 200b of the gel layer 200 will tend to have different firmnesses as perceived by a user of the body support article 600. Accordingly, if the first member of a couple sharing a bed expresses a preference for a first firmness perceived when the first gel lattice 110 is uppermost, and the second member of the couple expresses a preference for a second firmness perceived when the second gel lattice 210 is uppermost, the particular instance of the gel layer 200 to be positioned on their preferred side of the bed may be oriented such that the gel lattice 110, 210 having their preferred firmness is uppermost. This positioning may be effected during manufacturing, as will be discussed hereinafter, or upon the couple's taking of possession of the body support article 600.

In other embodiments, the body support article 400, 500, or 600 may further comprise at least one layer below the support layer 450.

Alternatively, or in addition, the body support article 400, 500, or 600 may further comprise at least one layer between the support layer 450 and the gel layer 200.

Any layer(s) above or below the support layer 450 may be formed of any appropriate material, such as a polymeric material, such as polyurethane; a viscoelastic material; a non-viscoelastic material; an elastomeric material; a gel; any material disclosed by any document incorporated herein by reference; or the like. The various layers may be bonded together by any suitable adhesive, may be coextruded, or may be fabricated and/or assembled using any process and/or equipment known in the art.

FIG. 22 shows an example of a mattress comprising from top to bottom a gel layer 200 (quilted, uppermost layer), an intervening layer delineated by dark bands, a support layer 450 (with sides presenting wavy diagonal lines), and a base layer.

In an alternative embodiment, the round gel segments 691 and the square gel segments 692 individual gel components that are isolated (e.g., by quilting, sewing, etc.) into separate sections for a body support article cover (e.g., a mattress cover, a pillow cover, a cushion cover, etc.). For example, the dotted lines 172 may represent quilt or sewing lines in the vertical direction, while the dotted lines 174 may represent quilt or sewing lines in the horizontal lines. In this manner the intersections of the lines 172 and 174 may represent separate sections of the body support article cover.

Turning now simultaneously to FIGS. 6B and 6C, side views of a body support article in accordance with some embodiments herein is illustrated. The body support article 600 may comprise a plurality of inner layers 618. The inner layer 618 depicted in FIGS. 6B and 6C may be representative of a plurality of layers, e.g., foam layers, support member layers, etc.

The inner layers 618 may be encapsulated by a cover layer 615. The cover layer 615 may be comprised of one or more materials, such as cloth material, foam material, etc.

In some embodiments, a gel layer 100 may be positioned above the inner layer 618. The gel layer 100 may then be encapsulated by the cover layer 615. The gel layer 100 may be divided into two regions, wherein a first gel lattice forms the first region of the gel layer 100 and a second gel lattice forms the second region of the gel layer 100. FIG. 6A exemplifies one embodiment of such first and second regions.

In some embodiments, the gel layer 100 may be positioned above the inner layer 618, but below a top layer 612, as shown in FIG. 6C. The top layer 612 may be one or a variety of types of layer, such as foam layer, support member layer, etc.

Further, in one embodiment, the split between the first and second regions of the gel layer 100 may be the center of the layer, wherein the first region may be the left side of the gel layer 100 and the second region may be the right side of the gel layer 100. The first region may express a first firmness while the second region may express a second firmness. In this manner, the gel layer 100 allows for a dual firmness expression for a body support article.

In alternative embodiments, the division between first and second regions of the gel layer 100 may not be the center of the gel layer 100. That is, the first region may occupy a greater than 50% of the total space of the gel layer 100, while the second region occupies less than 50% of the total gel layer 100, e.g., a 60%-40% split between the first and second regions of the gel layer 100, respectively. In some embodiments, the configuration of the first and second regions of the gel layer 100 may be customized based on consumer inputs, such as answers to questionnaire regarding customer preferences as to cooling, firmness, etc. of the body support article.
