The present disclosure relates generally to a mattress, and more particularly to a mattress having a foam structure including a plurality of slits to restrict a compression of the mattress to the areas under loading.
Mattresses typically include a foam layer disposed over a support layer that may include coil springs, water chambers, air chambers, foam etc. The foam layer is adapted to compress when the user lies on the mattress. In many instances however, foam layers have predictable shortcomings. One common shortcoming is that when foam is compressed, a concave depression can form, affecting the sleep experience of another person on the bed. Due to the formation of concave depression, sleeping partners may find themselves pulled or leaning towards the other party that they are sharing the mattress with. The concave depression (especially in very firm foams) can cause the posture to be affected negatively with their body in a position known as “kyphosis”, where the body is anatomically turned in on itself. Some foam also transfer motion readily from one side of the bed to the other. Another limitation of a layer of foam used in a mattress is that there is typically only one density or ILD (interior load deflection) to the foam.
According to an aspect of the disclosure, a mattress is provided. The mattress includes a layer including a first surface and a second surface arranged opposite to the first surface. The layer defines a plurality of slits extending from the first surface to the second surface and arranged in a plurality of rows extending in a longitudinal direction. The slits in each row are arrayed linearly in the longitudinal direction and are disposed spaced apart from each other. The rows of the slits restrict a compression of the layer to an area under loading and prevent the surrounding portion of the layer from being pulled towards the area under loading.
In one embodiment, the plurality of rows includes a plurality of first rows and a plurality of second rows arranged adjacent to the plurality of first rows. The slits of the first rows and the slits of the second rows are arranged in an inline arrangement. The plurality of rows also includes a plurality of third rows arranged adjacent to the plurality of second rows such that a single second row is arranged between a single first row and a single third row. The slits of the third row and the slits of the second row are arranged in a staggered arrangement. Moreover, the plurality of rows includes a plurality of fourth rows arranged adjacent to the plurality of third rows such that a single third row is arranged between a single fourth row and a single second row and the single fourth row is arranged between an adjacently arranged single third row and an adjacently arranged single first row. The slits of the fourth row and the slits of the third row are arranged in an inline arrangement.
In one embodiment each first row includes a number of slits arranged spaced apart from each other such that a first gap is defined between two consecutively arranged slits of the first row, and each second row includes a number of slits arranged spaced apart from each other such that a second gap is defined between two consecutively arranged slits of the second row. The second gap is disposed facing the first gap of the adjacently arranged first row and completely overlaps the facing first gap.
In one embodiment, each third row includes a number of slits arranged spaced apart from each other such that a third gap is defined between two consecutively arranged slits of the third row. The third gap is arranged facing the slit of the adjacently arranged second row such that the slit of the adjacently arranged second row completely overlaps the facing third gap. Further, each fourth row includes a number of slits arranged spaced apart from each other such that a fourth gap is defined between two consecutively arranged slits of the fourth row. The fourth gap is disposed facing the third gap of the adjacently arranged third row and completely overlaps the facing third gap.
In one embodiment, the fourth gap is arranged facing the slit of the adjacently arranged first row such that the slit of the adjacently arranged first row completely overlaps the facing fourth gap.

According to an aspect of the disclosure, a mattress is provided. The mattress includes a base structure and a foam structure attached to the base structure and supported on the base structure. The foam structure includes a layer having a first surface and a second surface arranged opposite to the first surface and defining a plurality of slits extending from the first surface to the second surface and arranged in a plurality of rows extending in a longitudinal direction. The slits in each row are arrayed linearly in the longitudinal direction and are disposed spaced apart from each other. The rows of the slits restrict a compression of the layer to an area under loading and prevent the surrounding portion of the layer from being pulled towards the area under loading.
In one embodiment, the plurality of rows includes a plurality of first rows and a plurality of second rows arranged adjacent to the plurality of first rows. The slits of the first rows and the slits of the second rows are arranged in an inline arrangement. The plurality of rows also includes a plurality of third rows arranged adjacent to the plurality of second rows such that a single second row is arranged between a single first row and a single third row. The slits of the third row and the slits of the second row are arranged in a staggered arrangement. Moreover, the plurality of rows includes a plurality of fourth rows arranged adjacent to the plurality of third rows such that a single third row is arranged between a single fourth row and a single second row and the single fourth row is arranged between an adjacently arranged single third row and an adjacently arranged single first row. The slits of the fourth row and the slits of the third row are arranged in an inline arrangement.
In one embodiment each first row includes a number of slits arranged spaced apart from each other such that a first gap is defined between two consecutively arranged slits of the first row, and each second row includes a number of slits arranged spaced apart from each other such that a second gap is defined between two consecutively arranged slits of the second row.

As shown in
Moreover, each third row 134 extends from the first longitudinal end 140 of the first layer 110 to the second longitudinal end 142 of the first layer 110 and includes a number of slits 120 of the plurality of slits 120. The number of slits 120 of the third row 134 are arrayed linearly along a longitudinal direction of the mattress 100 such that a third gap 154 is defined between two consecutive slits 120 of the third row 134. Further, the third row 134 is arranged adjacent/neighboring the second row 132 such that the second row 132 is arranged between the first row 130 and the third row 134. Similarly, each fourth row 136 extends from the first longitudinal end 140 of the first layer 110 to the second longitudinal end 142 of the first layer 110 and includes a number of slits 120 out of the plurality of the slits 120. The slits 120 of the fourth row 136 are arrayed linearly along a longitudinal direction and disposed spaced apart from each other in the longitudinal direction such that a fourth gap 156 is defined between two consecutive slits 120 of the fourth row 136. Further, the fourth row 136 is arranged adjacent/neighboring the third row 134 and the slits 120 of the third row 134 and the slits 120 of the fourth row 136 are arranged such that each slit 120 of the third row 134 completely overlaps an associated slit 120 of the fourth row 136 that is disposed facing the slit 120 of the third row 134. In such a case, the third gap 154 also completely overlaps the fourth gap 156. Accordingly, the slits 120 of the third row 134 and the slits 120 of the fourth row 136 are disposed in an inline arrangement.
Further, the fourth row 136 is arranged adjacent/neighboring the third row 134 such that the third row 134 is arranged between the second row 132 and the fourth row 136. As shown, the slits 120 of the third row 134 and the slits 120 of the second row 136 are arranged such that each slit 120 of the third row 134 partially overlaps two associated slit 120 of the second row 132 that are disposed facing the slit 120 of the third row 134. In such a case, the slit 120 of the third row 134 completely overlaps the second gap 152 disposed between the two facing slits 120 of the second row 132. Accordingly, a central axis of each slit 120 of the third row 134 is longitudinally offset from a central axis of each of the facing slits 120 of the second row 132. Also, the central axis of the slit 120 of the third row 134 is disposed facing the second gap 152. Accordingly, the slits 120 of the third row 134 and the slits 120 of the second row 132 are disposed in a staggered arrangement.
Also, the fourth row 136 is arranged between the first row 130 and the third row 134. Further, the fourth row 136 is arranged adjacent/neighboring the first row 130. As shown, the slits 120 of the fourth row 136 and the slits 120 of the first row 130 are arranged such that each slit 120 of the fourth row 136 partially overlaps two associated slit 120 of the first row 130 that are disposed facing the slit 120 of the fourth row 136. In such a case, the slit 120 of the fourth row 136 completely overlaps the first gap 150 disposed between the two facing slits 120 of the first row 130. Accordingly, a central axis of each slit 120 of the fourth row 136 is longitudinally offset from a central axis of each of the facing slits 120 of the first row 130. Also, the central axis of the slit 120 of the fourth row 136 is disposed facing the first gap 150. Accordingly, the slits 120 of the fourth row 136 and the slits 120 of the first row 130 are disposed in a staggered arrangement. Also, a spacing between two adjacent rows may be varied depending on the required firmness and/or softness of the first layer 110. Further, the dimensions of the slit 120 may vary depending upon the required softness or firmness of the first layer 110.

Although the mattress 100 having a first group of rows having two rows, for example, the first row 130 and the second row 132, followed by a second group of rows having two rows, for example, third row 134 and the fourth row 136 is contemplated. It may be appreciated that the first group of rows may include more than two rows, for example, three rows and the second group of rows may also include multiple rows, for example, three rows that are arranged in a similar manner. Further, although the slits 120 of the third row 134 and the slits of the fourth row 136 are shown to be arranged in the staggered arrangement relative to the slits 120 of the second row 132 and the first row 130, it may be envisioned that the slits 120 in all the rows, i.e., the first row 130, the second row 132, the third row 134, and the fourth row 136, may be arranged in an inline arrangement.
