TECHNICAL FIELD

This application pertains to foam mattresses, and more particularly, to a configurable foam comfort system.

BACKGROUND

People spend more time on their mattresses than anywhere else. This includes periods of relaxation, sleep, watching television, surfing the web, among other activities. Mattresses have become integral to nearly every person's life in our modern world of comforts and conveniences. Yet, while the materials used to construct mattresses have improved over time, the quality of mattresses varies widely, and even the best-quality conventional mattresses are nonetheless lacking in one or more areas such as comfort, configurability, or price point.

Accordingly, a need remains for an improved mattress, and in particular, a need remains for a configurable foam comfort system. Embodiments of the inventive concept address these and other limitations in the prior art.

FIG. 1 illustrates an example perspective view of a firm foam mattress foundation 105 of a configurable foam comfort system in accordance with various embodiments of the present inventive concept. FIG. 2 illustrates an example foam hexagonal cell 100

configurable on the firm foam mattress foundation 105 of FIG. 1. FIG. 3 illustrates multiple foam hexagonal cells 100 in a stacked honeycomb configuration 110 in accordance with various embodiments of the present inventive concept. Reference is now made to FIGs. 1 through 3.

The foam hexagonal cells 100 can lay horizontally on the firm foam mattress foundation 105. The foam hexagonal cells 100 can be stacked so they fit together in a honeycomb configuration as shown in the configuration 110. As such, the foam hexagonal cells 100 can be quickly and easily fit together in a non- shifting and stable arrangement. The horizontal cells 100 create a nesting-like pattern that supports each of the surrounding cells 100. Thus, the surrounding cells 100 in any particular configuration can directly support each near-by cell 100.

Each of the foam hexagonal cells 100 can include a first hexagonal face side 160 and a second hexagonal face side 161 opposite thereof. In addition, the foam hexagonal cells 100 can each include a first side wall 162, a second sidewall 163, a third sidewall 167, a fourth sidewall 165, a fifth sidewall 164, and a sixth sidewall 166. Each of the foam hexagonal cells 100 can be an elongate having a length that is substantially equal to a width of the firm foam mattress foundation 105.

The firm foam mattress foundation 105 can include form-fit walls 125, which are cut or otherwise formed so that they conform to the shape of the hexagonal cells 100, as further described below. This provides a secure and stable configuration of the foam hexagonal cells 100 within and on the firm foam mattress foundation 105.

The foam hexagonal cells 100 can have three different foam characteristics: 1) firm, 2) medium firm, and 3) soft. This allows a user to create a personalized support level by arranging the foam hexagonal cells 100 in various configurations depending on the characteristics of the cells. For example, firmer cells can be placed in the middle of the mattress foundation 105 to support the back, while softer cells can be placed near the area where the head rests. The shape of the configurable foam comfort system is modular and can be adjusted based on how many cells 100 are stacked in a given region. The cells 100 can be rearranged to create a customized comfort level and shape.

Moreover, individual hexagonal cells 100 can be replaced if warn or defective. For example, if the mid-section of the configurable foam comfort system creates a "sag" the user can swap cells in the mid-section with cells from other sections of the mattress that don't have any significant load baring need, such as the foot section. The structure of the foam hexagonal cells 100 allows the user to replace or repair broken-down components within the mattress foundation 105. In doing so, life of the mattress is extended. And for those components that must be replaced entirely, the manufacture can send smaller pieces of foam, instead of having to replace the entire sheet of foam, because of the modular design of the foam comfort system.

Moreover, the multiple density foams in the foam hexagonal cells 100 can provide different comfort levels. The surrounding cells of a particular cell can directly affect each cell. The multiple density or firmness levels of the cells 100 allows the user to create many different comfort levels by positioning and arranging the cells in unique orders and configurations.

FIG. 4 illustrates another example perspective view of a firm foam mattress foundation 105 of a configurable foam comfort system in accordance with various embodiments of the present inventive concept. FIG. 5 illustrates triangular grooves 102 in the firm foam mattress foundation 105 of FIG. 4. FIG. 6 illustrates a form-fit wall 125 of the firm foam mattress foundation of FIG. 4. Reference is now made to FIGs. 4 through 6.

The firm foam mattress foundation 105 can include any suitable number of triangular grooves 102. For example, the firm foam mattress foundation 105 can include an upper surface having a plurality of triangular grooves 102 disposed across a width thereof. Each of the triangular grooves 102 can provide a base for a corresponding foam hexagonal cell 100. In some embodiments, every triangular groove 102 is occupied by a corresponding foam hexagonal cell 100. In some embodiments, a subset of the total triangular grooves 102 is occupied by a corresponding foam hexagonal cell 100, and a remaining subset is unoccupied. Because the cell points of the foam hexagonal cells 100 face upwards and downwards, the triangular grooves 102 prevent the foam hexagonal cells 100 from moving around or shifting. With the vertical apex points of the foam hexagonal cells 100 facing upwards, additional foam pieces can be added to the structure in the event of a major repair on the base mattress foundation 105. In other words, the ^ΛΛΛΛΛ shape allows similar shapes to be used to fit within the ^ΛΛΛΛΛ groves to give the mattress a non-shifting surface. The additional pieces can have a base that looks like vvvvv, and can fit together such that they are prevented from shifting.

The form-fit wall 125 can include a nook 127 and an overhang portion 129. The nook 127 can be configured to easily receive and fit a foam hexagonal cell 100. The overhang portion 129 can partially overhang and secure the foam hexagonal cell 100 in place, but without creating an undue burden to rearrangement of the cells. Accordingly, the nook 127 and the overhang 129 of the form-fit wall 125 can provide stability to the foam hexagonal cells 100, particularly on the ends of the configurable foam comfort system, but without impeding the ease of reconfiguration of the foam hexagonal cells 100.

The nook 127 can receive and fit a particular foam hexagonal elongate cell 100. The overhang portion 129 can partially overhang and secure the particular foam hexagonal elongate cell 100 in place. The nook 127 can include a vertical side wall 150, a lower wall 152 oriented obliquely relative to the vertical side wall 150, and an upper wall 154 oriented obliquely relative to the vertical side wall 150. The overhang portion 129 can include a vertical side wall 156 and the upper wall 154 of the nook 127. The vertical side wall 150 of the nook 127 can make contact with a first side wall (e.g., 162 of FIG. 2) of the particular foam hexagonal elongate cell 100. The lower wall 152 of the nook 127 can make contact with a second side wall (e.g., 163 of FIG. 2) of the particular foam hexagonal elongate cell 100. The upper wall 154 of the nook 127 can make contact with a third side wall (e.g. , 167 of FIG. 2) of the particular foam hexagonal elongate cell 100. The vertical side wall 156 of the overhang portion 129 can make contact with a first side wall (e.g. , 162 of FIG. 2) of a different foam hexagonal elongate cell 100.

The firm foam mattress foundation 105 includes a first side 180 and a second side 182. The width 188 of the firm foam mattress foundation 105 extends from the first side 180 to the second side 182. The firm foam mattress foundation 105 includes a third side 184 and a fourth side 186. A length of the firm foam mattress foundation 105 extends from the third side 184 to the fourth side 186.

The third side 184 of the firm foam mattress foundation 105 can include a first form- fit wall (e.g. , 125) which can conform to a shape of each of the foam hexagonal elongate cells 100. The fourth side 186 of the firm foam mattress foundation 105 can include a second form-fit wall (e.g., 125) which conforms to a shape of each of the foam hexagonal elongate cells 100. FIG. 7 illustrates an example perspective view of multiple foam hexagonal cells 100 in a stacked configuration toward one end of and atop the firm foam mattress foundation 105 of FIG. 4. FIG. 8 illustrates another example perspective view of multiple foam hexagonal cells 100 in a stacked configuration toward the one end of and atop the firm foam mattress foundation 105 of FIG. 4. FIG. 9 illustrates an example perspective view of multiple foam hexagonal cells 100 in a stacked configuration in a central region of and atop the firm foam mattress foundation 105 of FIG. 4. Reference is now made to FIGs. 7 through 9.

As shown in these figures, the foam hexagonal cells 100 fit snuggly against the form- fit wall 125. Each of the foam hexagonal cells 100 has a length that substantially matches a width of the firm foam mattress foundation 105. In other words, face sides of the foam hexagonal cells 100 are substantially flush with sides of the firm foam mattress foundation 105. Although shown as stacked two-deep, it will be understood that the foam hexagonal cells 100 can be stacked one-deep, two-deep, three-deep, four-deep, five-deep, or more, or even zero-deep, depending on the desired mattress contours of the user. Accordingly, the configurable foam comfort system provides a configurable shape based on the preferences of the user.

The configurable foam comfort system can include multiple foam hexagonal elongate cells 100 configured to fit partially within corresponding triangular grooves (e.g. , 102) disposed across the width of the firm foam mattress foundation 105. In some embodiments, a length of each of the foam hexagonal elongate cells 100 is substantially equal to the width of the firm foam mattress foundation 105. The foam hexagonal elongate cells 100 are configured to be custom-stacked on each other and on the firm foam mattress foundation 105 in accordance with a user's desired comfort configuration.

FIG. 10 illustrates multiple foam hexagonal cells 100 in a uniform stacked

configuration atop the firm foam mattress foundation 105, along with multiple top layers 120 disposed on the foam hexagonal cells 100 in accordance with various embodiments of the present inventive concept. Although multiple top layers 120 are shown, it will be understood that one or more top layers 120 can be disposed atop the hexagonal cells 100 and the firm foam mattress foundation 105. The one or more top layers 120 can include memory foam and/or latex materials. As described above, the foam hexagonal cells 100 can be arranged with different cells having different firmness characteristics in different sections of the configurable foam comfort system. The base mattress foundation 105 supports any suitable number of foam layers 120 on top of the customized foam hexagonal cell configuration, thereby providing a unique base configuration and shape according to the preferences of the user.

The foam hexagonal elongate cells 100 can include a first plurality of foam hexagonal elongate cells (e.g. , Ill) and a second plurality of foam hexagonal elongate cells (e.g. , 170) configured to fit atop the first plurality of foam hexagonal elongate cells 172. The first plurality of foam hexagonal elongate 172 cells and the second plurality of foam hexagonal elongate cells 170 can form a honeycomb pattern when viewed from the side.

The first plurality of foam hexagonal elongate cells 172 collectively form an upper surface having a plurality of triangular grooves 158. The second plurality of foam hexagonal elongate cells 170 are configured to fit partially within corresponding triangular grooves 158 of the upper surface of the first plurality of foam hexagonal elongate cells 172.

The first plurality of foam hexagonal elongate cells 172 are configured to extend horizontally from the first side (e.g., 180 of FIG. 4) to the second side (e.g. , 182 of FIG. 4) of the firm foam mattress foundation 105 when the first plurality of foam hexagonal elongate cells 172 are fit partially within the corresponding triangular grooves 102 disposed across the width of the firm foam mattress foundation 105. The second plurality of foam hexagonal elongate cells 170 are configured to extend horizontally from the first side 180 to the second side 182 of the firm foam mattress foundation 105 when the second plurality of foam hexagonal elongate cells 170 are fit partially within the corresponding triangular grooves 158 of the upper surface of the first plurality of foam hexagonal elongate cells 172. In some embodiments, each of the second plurality of foam hexagonal elongate cells 170 have a length that is substantially equal to the width (e.g. , 188 of FIG. 4) of the firm foam mattress foundation 105.

In some embodiments, one or more rectangular foam top layers 120 are disposed atop a plurality of foam hexagonal elongate cells 170. The one or more rectangular foam top layers 120 can each include a planar upper surface and a planar lower surface. The planar lower surface (e.g. , 187) can be in contact with an apex 185 of each of the plurality of foam hexagonal elongate cells 170. In some embodiment, the one or more rectangular foam top layers 120 include a first foam top layer and a second foam top layer disposed atop the first foam top layer. At least one of the first foam top layer or the second foam top layer can include or otherwise be constructed from memory foam.

FIG. 11 illustrates multiple foam hexagonal cells 100 in a uniform stacked

configuration with a foam body support section 130 disposed over a subset of the foam hexagonal cells 100 to provide a raised arcuate upper surface section in accordance with various embodiments of the present inventive concept. The foam body support section 130 can be disposed atop the foam hexagonal cells 100 to provide a raised arcuate upper surface section 194 in any suitable location according to the preferences of the user. The foam body support section 130 can provide support for parts of a human body, such as a human head, a human back, human legs, or human feet. The length of the foam body support section 130 can extend width-wise horizontally from one side of the foam mattress foundation to another. Alternatively, the length of the foam body support section 130 can be less than the width of the foam mattress foundation.

The foam body support section 130 can be disposed atop a subset (e.g. , 192) of foam hexagonal elongate cells 100 and under the one or more rectangular foam top layers 120. In some embodiments, the foam body support section 130 includes a raised arcuate upper surface section 194. The subset 192 of foam hexagonal elongate cells 100 can collectively form an upper surface having a plurality of triangular grooves. The foam body support section 130 can include a lower section 196 having a plurality of triangular grooves configured to fit together with the triangular grooves of the upper surface of the subset 192 of foam hexagonal elongate cells 100.

The configurable foam mattress comfort system can include various layers (e.g. , 197, 198, and 199) of foam hexagonal elongate cells 100. Each layer of hexagonal elongate cells 100 are configured to extend horizontally from the first side to the second side of the firm foam mattress foundation 105. The top layer 199 is configured to fit partially within corresponding triangular grooves 159 of an upper surface of the middle layer 198 of foam hexagonal elongate cells 100. The middle layer 198 is configured to fit partially within corresponding triangular grooves 158 of an upper surface of the lower layer 198 of foam hexagonal elongate cells 100. A combination of the first, the second, and the third layers of foam hexagonal elongate cells is rearrangeable to create a customized comfort level and shape.

One or more foam hexagonal elongate cells from among the bottom layer 197, the middle layer 198, and the top layer 199 of foam hexagonal elongate cells 100 can include a first firmness characteristic such as firm. One or more foam hexagonal elongate cells from among the bottom layer 197, the middle layer 198, and the top layer 199 of foam hexagonal elongate cells 100 can include a second firmness characteristic such as medium firm. One or more foam hexagonal elongate cells from among the bottom layer 197, the middle layer 198, and the top layer 199 of foam hexagonal elongate cells 100 can include a third firmness characteristic such as soft.

The foam 'M' shaped cells 135 fit together and provide a non- shifting and stable arrangement, such that the foam 'M' shaped cells 135 can be stacked on top of each other to form a different firmness according to preference, and according to a modular design. The firm foam mattress foundation 145 can include vertical walls 155, which need not be cut to conform to the shape of the 'M' shaped cells 135, since edges of the 'M' shaped cells 135 form a vertical wall themselves. In other words, the 'M' shaped cells 135 can fit against the ends of the firm foam mattress foundation 145 without any nooks or overhangs. This provides a secure and stable configuration of the 'M' shaped cells 135 on the firm foam mattress foundation 145. As shown in FIG. 16, a foam body support section 130 can be added to provide a raised arcuate upper surface section 194.

The third layer 178 of foam 'M' shaped elongate cells 135 are configured to fit partially within corresponding triangular grooves 149 of the upper surface of the second layer 177 of foam 'M' shaped elongate cells 135.

The firm foam mattress foundation 145 can include a first side 121 and a second side

122. The width of the firm foam mattress foundation 145 extends from the first side 121 to the second side 122. The firm foam mattress foundation 145 can include a third side 123 and a fourth side 124. A length of the firm foam mattress foundation extends from the third side 123 to the fourth side 124.

The first layer 176 of foam 'M' shaped elongate cells 135 are configured to extend horizontally from the first side 121 to the second side 122 of the firm foam mattress foundation 145 when the first layer 176 of foam 'M' shaped elongate cells 135 are fit partially within the corresponding triangular grooves 147 disposed across the width of the firm foam mattress foundation 145. The second layer 177 of foam 'M' shaped elongate cells 135 are configured to extend horizontally from the first side 121 to the second side 122 of the firm foam mattress foundation 145 when the second layer 177 of foam 'M' shaped elongate cells 135 are fit partially within the corresponding triangular grooves 148 of the upper surface of the first layer 176 of foam 'M' shaped elongate cells 135. The third layer 178 of foam 'M' shaped elongate cells 135 are configured to extend horizontally from the first side 121 to the second side 122 of the firm foam mattress foundation 145 when the third layer 178 of foam 'M' shaped elongate cells 135 are fit partially within the corresponding triangular grooves 149 of the upper surface of the second layer 177 of foam 'M' shaped elongate cells 135.

Each of the second layer 177 of foam 'M' shaped elongate cells 135 have a length that is substantially equal to the width of the firm foam mattress foundation 145. The third side conforms to a shape of each of the foam 'M' shaped elongate cells 135 from each of the layers 176, 177, and 178. The fourth side 124 of the firm foam mattress foundation 145 includes a second vertical wall 155, which conforms to a shape of each of the foam 'M' shaped elongate cells 135 from each of the layers 176, 177, and 178.

The configurable foam mattress comfort system can further include one or more rectangular foam top layers 120 disposed atop the foam 'M' shaped elongate cells 135. The one or more rectangular foam top layers 120 include a planar upper surface and a planar lower surface. The planar lower surface can be in contact with an apex 185 of each of the foam 'M' shaped elongate cells 135, for example, of the upper layer 178. The one or more rectangular foam top layers 120 can include a first foam top layer and a second foam top layer disposed atop the first foam top layer. At least one of the first foam top layer or the second foam top layer can include memory foam.

The configurable foam mattress comfort system can further include a foam body support section 130 disposed atop a subset of foam 'M' shaped elongate cells 135 and under the one or more rectangular foam top layers 120. The foam body support section 130 can include a raised arcuate upper surface section 194. The foam 'M' shaped elongate cells (e.g. , from layer 178) collectively form an upper surface having a plurality of triangular grooves 151. The foam body support section 130 can include a lower section 196 having a plurality of triangular grooves 153 configured to fit together with the plurality of triangular grooves 151 of the upper surface of the layer of plurality of foam 'M' shaped elongate cells 178.

A combination of the first layer 176, the second layer 177, and the third layer 178 of foam 'M' shaped elongate cells 135 is rearrangeable to create a customized comfort level and shape. One or more foam 'M' shaped elongate cells 135 from among the first layer 176, the second layer 177, and the third layer 178 of foam 'M' shaped elongate cells can include a first firmness characteristic, such as firm. One or more foam 'M' shaped elongate cells 135 from among the first layer 176, the second layer 177, and the third layer 178 of foam 'M' shaped elongate cells can include a second firmness characteristic, such as medium firm. One or more foam 'M' shaped elongate cells 135 from among the first layer 176, the second layer 177, and the third layer 178 of foam 'M' shaped elongate cells can include a third firmness characteristic, such as soft. The firm characteristic can indicate a firmness greater than the firmness of medium firm. The soft characteristic can indicate a softness greater than the softness of medium firm.
