[0030] Please see Figures 1 to 2 In some embodiments, the mattress 100 includes a support layer 101 and a support layer 103, with the support layer 101 stacked on top of the support layer 103.

[0031] The support layer 101 is stacked on the support layer 103, which can mean that the support layer 101 is stacked on the support layer 103 along the thickness direction Z. When the mattress 100 is placed on the bed frame, the support layer 101 can be located above the support layer 103 or below the support layer 103.

[0032] The support layer 101 has a different firmness than the support layer 103, allowing users to flip the mattress 100 to choose either the support layer 101 or the support layer 103 as the direct contact layer during sleep, thus meeting different user needs regarding mattress firmness. The firmness of the support layer 101 can be greater than that of the support layer 103, or vice versa.

[0033] As an example, if the support layer 101 can serve as the direct contact layer when the user is sleeping, then the support layer 103 can be supported between the bed frame and the support layer 101.

[0034] As another example, if the support layer 103 can serve as the direct contact layer when the user is sleeping, then the support layer 101 can be supported between the bed frame and the support layer 103.

[0035] The support layer 101 includes at least two support areas 110, which are distributed sequentially along the first direction X and have progressively increasing thicknesses, meaning that the thickness of each support area 110 is different. The first direction X is the width direction of the mattress.

[0036] "Distribution in sequence" can refer to either sequentially spaced distribution or sequentially connected distribution.

[0037] The first direction X can refer to the direction from the user's left hand to the right hand or from the user's right hand to the left hand when the user is lying on the mattress 100 to sleep.

[0038] The support layer 103 includes at least two support areas 170, which are distributed sequentially along the first direction X and have progressively decreasing thicknesses, meaning that the thickness of each support area 170 is different.

[0039] Each support area 170 is stacked on a corresponding support area 110, such that the sum of the thicknesses of each support area 110 and the corresponding support area 170 is the first thickness. Thus, the mattress 100 can have multiple different sleeping areas distributed along the first direction X. Each sleeping area is stacked with support areas 110 and support areas 170 of different thicknesses, so that each sleeping area can provide users with different sleeping sensations and meet the sleep needs of different users.

[0040] As an example, consider a mattress 100 with a first sleeping area and a second sleeping area distributed sequentially along the first direction X, where the support layer 103 is supported between the bed frame and the support layer 101, the support layer 101 has a firmness greater than that of the support layer 103, and the support layer 103 is supported by a support area 110 and a support area 170, respectively. Understandably, each of the first and second sleeping areas corresponds to a stacked support area 110 and a support area 170.

[0041] In the first sleeping area, the support layer 101 is firmer and thinner. For elderly users, the support layer 101 provides sufficient support to prevent the body from sinking excessively into the mattress 100, making it easier for them to turn over or sit up. The thinner support layer 101 is also more flexible to better conform to the user's body curves, reducing the feeling of being unsupported and mitigating the overly firm feel that could result from the firmness of the support layer 101. It provides more even support to the user. Meanwhile, the support area 170 is less firm and thicker, which can slowly absorb body pressure, reducing vibration transmission when the user turns over and minimizing the impact of the mattress 100 on the user's joints.

[0042] In the second sleeping area, the support layer 101 is firmer and thicker, providing stronger support for heavier users. Furthermore, the thicker support layer 101 distributes pressure more evenly to the support area 170, contributing to more uniform support. Conversely, the support area 170 is less firm and thinner, exhibiting better deformability to absorb the impact of heavy users lying down.

[0043] In some embodiments, the support layer 101 can be one of a memory foam layer, a latex layer, and a cold foam layer, so that the support layer 101 can be made of different materials to provide users with different sleep sensations.

[0044] In some embodiments, the support layer 103 can be one of a memory foam layer, a latex layer, and a cold foam layer, so that the support layer 103 can be made of different materials to provide users with different sleep sensations.

[0045] The support layer 101 and the supporting layer 103 can be made of the same material or different materials.

[0046] As an example, both the support layer 101 and the supporting layer 103 can be memory foam layers, or both the support layer 101 and the supporting layer 103 can be latex layers, or both the support layer 101 and the supporting layer 103 can be cold foam layers.

[0047] As another example, the support layer 101 can be a memory foam layer, and the support layer 103 can be either a latex layer or a cold foam layer.

[0048] Understandably, the support layer 101 and the supporting layer 103 can be made of different materials to give them different hardnesses. When the support layer 101 and the supporting layer 103 are made of the same material, the manufacturing process can be adjusted to give them different densities, thereby resulting in different hardnesses.

[0049] In some embodiments, a central axis is defined passing through the geometric center of the support layer 101 and the geometric center of the support layer 103, and the central axis extends along the thickness direction Z.

[0050] Among them, the support layer 101 and the supporting layer 103 are 180 degrees rotationally symmetrical about the central axis, which can improve the utilization rate of materials and reduce the manufacturing cost of the bed sheet.

[0051] As an example, taking two mattresses 100 as an example, the two mattresses 100 are named the first mattress 100 and the second mattress 100, respectively. The support layer 101 and the support layer 103 of the first mattress 100 are named the first support layer 101 and the first support layer 103, respectively. The support layer 101 and the support layer 103 of the second mattress 100 are named the second support layer 101 and the second support layer 103, respectively. The first mattress 100 and the second mattress 100 can be made of first foam blocks and second foam blocks with different firmness. Specifically, by utilizing the 180-degree rotational symmetry between the support layer 101 and the support layer 103, the first sponge block can be directly cut into the first support layer 101 and the second support layer 103, and the second sponge block can also be directly cut into the second support layer 101 and the first support layer 103. The first support layer 101 and the first support layer 103 can be stacked and fitted together to form the first mattress 100, and the second support layer 101 and the second support layer 103 can be stacked and fitted together to form the second mattress 100. In this way, four layers of sponge can be cut from the first sponge block and the second sponge block, namely the first support layer 101, the first support layer 103, the second support layer 101, and the second support layer 103, and two mattresses 100 can be assembled, thereby improving the utilization rate of the first sponge block and the second sponge block.

[0052] In some embodiments, at least two support areas 110 may include a first support area 111 and a second support area 113 arranged adjacent to each other, and at least two support areas 170 may include a first support area 171 and a second support area 173 arranged adjacent to each other.

[0053] The first support area 111 is stacked on top of the first support area 171, and the second support area 113 is stacked on top of the second support area 173, so that the mattress 100 can form two sleeping areas. The first support area 111 and the second support area 113 can be connected to each other or opposite each other and spaced apart, and the first support area 171 and the second support area 173 can be connected to each other or opposite each other and spaced apart.

[0054] The thickness of the first support area 171 can be greater than the thickness of the second support area 173, and the thickness of the second support area 113 can be greater than the thickness of the first support area 111. This allows the two sleep areas to provide different sleep sensations for different users (e.g., couples), meeting the sleep needs of different users. Specifically, the first support area 171 and the second support area 173 are distributed sequentially along the first direction X, and the first support area 111 and the second support area 113 are also distributed sequentially along the first direction X.

[0055] The thickness of the first support area 171 can also be greater than the thickness of the first support area 111, and the thickness of the second support area 113 can also be greater than the thickness of the second support area 173, so that the two sleeping areas can provide users with different sleeping sensations before and after the mattress 100 is flipped over.

[0056] In some embodiments, the support layer 101 may further include a transition region 130, and the supporting layer 103 may further include a connecting region 190, wherein the transition region 130 may be stacked on the connecting region 190.

[0057] The transition zone 130 can be connected between the first support zone 111 and the second support zone 113. The thickness of the transition zone 130 can gradually increase along the direction from the first support zone 111 to the second support zone 113, thereby making the thickness transition between the first support zone 111 and the second support zone 113 smoother. The transition zone 130 can improve the smoothness of the hardness transition between the first support zone 111 and the second support zone 113, which helps to improve the user experience.

[0058] The connecting area 190 can be connected between the first support area 171 and the second support area 173. The thickness of the connecting area 190 can gradually decrease along the direction from the first support area 171 to the second support area 173, thereby making the thickness transition between the first support area 171 and the second support area 173 smoother. The connecting area 190 can improve the smoothness of the hardness transition between the first support area 171 and the second support area 173, which helps to improve the user's experience.

[0059] In some embodiments, the mattress 100 may further include an adhesive layer that can be bonded between the support layer 101 and the support layer 103, thereby connecting and fixing the support layer 101 and the support layer 103 and reducing the possibility of displacement between the support layer 101 and the support layer 103.

[0060] Specifically, the support area 110 and the corresponding support area 170 can be bonded together by an adhesive layer, and the transition area 130 and the connecting area 190 can also be bonded together by an adhesive layer.

[0061] The adhesive layer can be made of environmentally friendly hot melt adhesive film, aerosol spray adhesive or other adhesives.

[0062] In some embodiments, the first support area 111 includes a first contact surface 1111, the second support area 113 includes a second contact surface 1131, the transition area 130 includes a transition surface 131, the first support area 171 includes a first connecting surface 1711, the second support area 173 includes a second connecting surface 1731, and the connecting area 190 includes a connecting surface 191.

[0063] The transition surface 131 can be connected between the first contact surface 1111 and the second contact surface 1131, thereby ensuring the continuity of the surface of the support layer 101 facing the support layer 103.

[0064] The connecting surface 191 can be connected between the first connecting surface 1711 and the second connecting surface 1731, thereby ensuring the continuity of the surface of the support layer 103 facing the support layer 101.

[0065] The first contact surface 1111 is superimposed on the first connecting surface 1711, the second contact surface 1131 is superimposed on the second connecting surface 1731, and the transition surface 131 is superimposed on the connecting surface 191. This increases the contact area between the first support area 111 and the first support area 171, the contact area between the transition area 130 and the connecting area 190, and the contact area between the second support area 113 and the second support area 173, which helps to make the overall firmness of the mattress 100 smoother.

[0066] As an example, both the transition surface 131 and the connecting surface 191 can be inclined. Specifically, the first contact surface 1111 and the second contact surface 1131 can have a height difference along the thickness direction Z of the mattress 100, and the transition surface 131 can be inclined to connect the first contact surface 1111 and the second contact surface 1131. The first connecting surface 1711 and the second connecting surface 1731 can have a height difference along the thickness direction Z of the mattress 100, and the connecting surface 191 can be inclined to connect the first connecting surface 1711 and the second connecting surface 1731.

[0067] In some embodiments, the first contact surface 1111 and the transition surface 131 can be connected by an arc transition, which can improve the situation where the first contact surface 1111 and the transition surface 131 are set at sharp angles, and help to improve the smoothness of the hardness transition between the first support area 111 and the transition area 130.

[0068] Curved surfaces can be made up of one or more of the following: convex curved surfaces and concave curved surfaces.

[0069] In some embodiments, the second contact surface 1131 and the transition surface 131 can be connected by an arc transition, which can improve the situation where the second contact surface 1131 and the transition surface 131 are set at sharp angles, and help to improve the smoothness of the hardness transition between the second support area 113 and the transition area 130.

[0070] In some embodiments, the first connecting surface 1711 and the connecting surface 191 can be connected by an arc transition, which can improve the situation where the first connecting surface 1711 and the connecting surface 191 are set at sharp angles, and help to improve the smoothness of the hardness transition between the first support area 171 and the connecting area 190.

[0071] In some embodiments, the second connecting surface 1731 and the connecting surface 191 can be connected by an arc transition, which can improve the situation where the second connecting surface 1731 and the connecting surface 191 are set at sharp angles, and help to improve the smoothness of the hardness transition between the second support area 173 and the connecting area 190.

[0072] In some embodiments, the support layer 101 may include a support plane 150, and the support layer 103 may include a support plane 210.

[0073] Among them, the surfaces of the first support area 111, the transition area 130, and the second support area 113 facing away from the support layer 103 along the thickness direction Z can be coplanar and interconnected to form a support plane 150. Specifically, the surfaces of the first support area 111 facing away from the first support area 171 along the thickness direction Z, the transition area 130 facing away from the connecting area 190 along the thickness direction Z, and the second support area 113 facing away from the second support area 173 along the thickness direction Z are coplanar and interconnected to form a support plane 150.

[0074] The surfaces of the first support area 171, the connecting area 190, and the second support area 173 facing away from the support layer 101 along the thickness direction Z can be coplanar and interconnected to form a support plane 210. Specifically, the surfaces of the first support area 171 facing away from the first support area 111 along the thickness direction Z, the connecting area 190 facing away from the transition area 130 along the thickness direction Z, and the second support area 173 facing away from the second support area 113 along the thickness direction Z are coplanar and interconnected to form a support plane 210.

[0075] Understandably, when the user selects support layer 101 to face upwards, support plane 150 can directly contact and support the user, while support plane 210 abuts against the bed frame. When the user selects support layer 103 to face upwards, support plane 210 can directly contact and support the user, while support plane 150 abuts against the bed frame.

[0076] The supporting plane 150, the first contact surface 1111, the second contact surface 1131, the first connecting surface 1711, the second connecting surface 1731, and the supporting plane 210 are parallel to each other, thereby ensuring that the thickness of each supporting area 110 and each supporting area 170 is uniform, and the hardness of each supporting area 110 and each supporting area 170 is also more uniform, which can provide more uniform support force.

[0077] The first thickness is approximately the distance between the supporting plane 150 and the bearing plane 210.

[0078] In some embodiments, the first thickness is defined as h, and the extension length of the transition surface 131 and the connecting surface 191 along the first direction X is L, wherein 2h≤L≤3h, which helps to make the hardness transition between the first support area 111 and the second support area 113 smoother, and the hardness transition between the first support area 171 and the second support area 173 smoother.

[0079] As an example, L can take the values ​​2h, 2.2h, 2.5h, 3h, or other values ​​in [2h, 3h].

[0080] In some embodiments, the transition surface 131 may extend along the first direction X in a smooth curve (NURBS) pattern, which helps to make the transition of thickness and hardness of the transition region 130 smoother.

[0081] The connecting surface 191 can extend in a smooth curve along the first direction X, which helps to make the transition of thickness and hardness of the connecting area 190 smoother.

[0082] In some embodiments, the transition surface 131 may include a first transition sub-surface 1311, a second transition sub-surface 1313, and a third transition sub-surface 1315, and the connecting surface 191 includes a first connecting sub-surface 1911, a second connecting sub-surface 1913, and a third connecting sub-surface 1915.

[0083] The first transition sub-surface 1311 can be connected between the first contact surface 1111 and the second transition sub-surface 1313, and the third transition sub-surface 1315 can be connected between the second transition sub-surface 1313 and the second contact surface 1131, so as to ensure the continuity of the surface of the support layer 101 facing the support layer 103.

[0084] The first connecting surface 1911 can be connected between the first connecting surface 1711 and the second connecting surface 1913, and the third connecting surface 1915 can be connected between the second connecting surface 1913 and the second connecting surface 1731 to ensure the continuity of the surface of the support layer 103 facing the support layer 101.

[0085] Along the thickness direction Z, the first transition sub-surface 1311 is stacked on the first connecting sub-surface 1911, the second transition sub-surface 1313 is stacked on the second connecting sub-surface 1913, and the third transition sub-surface 1315 is stacked on the third connecting sub-surface 1915.

[0086] In some embodiments, the first transition sub-surface 1311 may be provided as a concave arc surface, thereby connecting the first contact surface 1111 and the second transition sub-surface 1313 more smoothly, which helps to improve the smoothness of the hardness transition between the first support region 111 and the transition region 130.

[0087] The third transition surface 1315 can be provided as an outwardly convex arc surface, so as to connect the second transition surface 1313 and the second contact surface 1131 more smoothly, which helps to improve the smoothness of the hardness transition between the transition area 130 and the second support area 113.

[0088] The second transition sub-surface 1313 can be set at an angle, so that the first transition sub-surface 1311 and the third transition sub-surface 1315 can be connected more smoothly, which helps to make the overall hardness transition of the transition zone 130 smoother.

[0089] As an example, the second transition sub-surface 1313 can be tangent to the first transition sub-surface 1311 and the third transition sub-surface 1315 respectively, the first contact surface 1111 can be tangent to the first transition sub-surface 1311, and the second contact surface 1131 can be tangent to the second transition sub-surface 1313.

[0090] In some embodiments, the first connecting surface 1911 may be provided with an outwardly convex arc surface, thereby connecting the first connecting surface 1711 and the second connecting surface 1913 more smoothly, which helps to improve the smoothness of the hardness transition between the first support area 171 and the connecting area 190, and can increase the contact area between the first connecting surface 1911 and the first transition surface 1311.

[0091] The third connecting surface 1915 can be set as a concave arc surface, so that the second connecting surface 1913 and the second connecting surface 1731 can be connected more smoothly, which helps to improve the smoothness of the hardness transition between the connecting area 190 and the second supporting area 173, and can increase the contact area between the third connecting surface 1915 and the third transition surface 1315.

[0092] The second connecting surface 1913 can be inclined, so that the first connecting surface 1911 and the third connecting surface 1915 can be connected more smoothly, which helps to make the overall hardness transition of the connecting area 190 smoother and can increase the contact area between the second connecting surface 1913 and the second transition surface 1313.

[0093] As an example, the second connecting surface 1913 can be tangent to the first connecting surface 1911 and the third connecting surface 1915 respectively, the first connecting surface 1711 can be tangent to the first connecting surface 1911, and the second connecting surface 1731 can be tangent to the second connecting surface 1913.

[0094] In the mattress 100 provided in this embodiment, by setting the hardness of the support layer 101 and the support layer 103 to be different, the user can flip the mattress 100 to select either the support layer 101 or the support layer 103 as the direct contact layer during sleep, thus meeting the user's different needs for the firmness of the mattress 100. By setting the thickness of at least two support areas 110 to increase sequentially along the first direction X, and setting the thickness of at least two support areas 170 to decrease sequentially along the first direction X, each support area 110 is stacked on a corresponding support area 170, and the sum of the thicknesses of each support area 110 and the corresponding support area 170 is the first thickness, the mattress 100 can thus have multiple different sleeping areas distributed along the first direction X. Each sleeping area is stacked with support areas 110 and support areas 170 of different thicknesses, so that each sleeping area can provide the user with different sleep sensations and meet the sleep needs of different users.

However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
