[0050] In the present invention, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features between them. Moreover, the first feature being "above", "over" and "on" the second feature includes the first feature being directly above and obliquely above the second feature, or merely indicating that the first feature has a higher horizontal height than the second feature. The first feature being "below", "under" and "beneath" the second feature includes the first feature being directly below and obliquely below the second feature, or merely indicating that the first feature has a lower horizontal height than the second feature.

[0051] In the description of this embodiment, the orientation or positional relationships such as "upper", "lower", "right", etc. are based on the orientation or positional relationships shown in the drawings. They are only for the convenience of description and simplifying the operations, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0052] Most of the current mattress products on the market provide support surfaces with different hardnesses on the front and back sides of the mattress for users to flip the mattress according to their own needs and choose one of the two support hardnesses to switch the support hardness of the mattress. Not only do they need to clean the bedding and reinstall the sheets and mattress covers before flipping, which is very inconvenient to use, but also the available soft and hard degrees are very limited and the flexibility is insufficient. There are also some other mattress products on the market that can adjust the soft and hard degrees by replacing the support materials of the mattress, but the operation is troublesome and usually adjusted by professionals. Users cannot operate it by themselves, and they cannot adjust the support hardness in zones either.

[0053] Based on the above problems, this embodiment provides an adjustable soft and hard degree magic cube mattress, aiming to solve the problems of convenience, flexibility of soft and hard degree adjustment, and zonal adjustment. The soft and hard degree referred to in this embodiment means the support softness of the mattress. As Figure 1 shown, the magic cube mattress includes a top surface quilting layer 30, a composite support layer 10, an elastic support layer 20, and a bottom surface quilting layer 40 arranged from top to bottom. Among them, the composite support layer 10 includes a support quilting 1, a border structure 2, and a plurality of magic cube modules 3 with different soft and hard degrees. The support quilting 1 is connected above the elastic support layer 20. The border structure 2 is arranged along the circumference of the support quilting 1 and encloses to form a receiving groove 101. The magic cube modules 3 are installed in the receiving groove 101. The magic cube modules 3 are made of flexible materials. A plurality of independent spring cylinders are arranged in the elastic support layer 20. The magic cube modules 3 cooperate with the elastic support layer 20 to provide users with an elastic, soft, and comfortable support experience. It should be noted that the magic cube mattress is essentially a modular mattress. The support layer with adjustable support strength is formed by modular splicing of a plurality of magic cube modules 3. The dynamic support adaptation of different regions of the mattress is realized through the splicing technology. Since its modular splicing structure is similar to the single-sided structure of a magic cube, this modular mattress is vividly named the magic cube mattress, and the adjustable support module is named the magic cube module 3.

[0054] Furthermore, as Figure 1As shown, the Rubik's Cube module 3 is installed in the accommodation groove 101 in a detachable manner. A plurality of Rubik's Cube modules 3 in the accommodation groove 101 are arranged in a matrix. The softness and hardness of the plurality of Rubik's Cube modules 3 are not the same. The top surface quilting layer 30 and the surrounding structure 2 are fixedly connected by a first zipper 51 extending around the outer periphery. When the first zipper 51 is opened, the accommodation groove 101 is opened, allowing the user to replace the Rubik's Cube module 3 in the accommodation groove 101.

[0055] Specifically, for the Rubik's Cube mattress provided in this embodiment, a composite support layer 10 is provided between the elastic support layer 20 and the top surface quilting layer 30. In the composite support layer 10, the surrounding structure 2 is arranged along the circumference of the support quilting 1 and encloses to form an accommodation groove 101. The Rubik's Cube module 3 is detachably installed in the accommodation groove 101 and is arranged in a matrix. The user can open and close the accommodation groove 101 through the first zipper 51 between the top surface quilting layer 30 and the surrounding structure 2. After opening the accommodation groove 101, the user can adjust the support softness and hardness of the whole body or different body parts according to personal support softness and hardness requirements, and select and install the Rubik's Cube module 3 with the corresponding softness and hardness; or for the double-user usage scenario of a double bed, respectively adapt to the different support requirements of the two users, and install the Rubik's Cube module 3 with the corresponding softness and hardness in the corresponding area to achieve zonal adjustment. In summary, the Rubik's Cube mattress provided in this embodiment allows the user to install and replace the Rubik's Cube modules 3 with different softness and hardness by themselves, realizing zonal adjustment of the support softness and hardness, so as to flexibly adapt to the personalized support needs of the user, and the operation is simple. In addition, the Rubik's Cube module 3 can be elastically stretched and contracted, which is convenient for compression, carrying and storage. When a single Rubik's Cube module 3 is damaged, it can be replaced separately, which can save resources and extend the service life of the mattress.

[0056] Exemplarily, the surrounding structure 2 includes a surrounding cloth cover and four surrounding cotton strips. The surrounding cloth cover is arranged in a "mouth" - shaped structure extending along the circumference of the support quilting 1. The surrounding cloth cover is fixed to the support quilting 1 by sewing. The four surrounding cotton strips are all arranged in the surrounding cloth cover and are respectively arranged corresponding to the four side edges of the support quilting 1. The four surrounding cotton strips are joined end to end to form the side wall structure of the accommodation groove 101. With the surrounding structure 2 of this structure, it can solve the problems that the surrounding cotton strips at the edge of the composite support layer 10 of the Rubik's Cube mattress are easily soiled and damaged due to long-term exposure, and by wrapping the surrounding cotton strips with the surrounding cloth cover and then sewing and fixing it on the support quilting 1, it can also make the surface flatness of the surrounding cloth cover and the composite support layer 10 higher, not easy to appear wrinkles, and improve the aesthetics.

[0057] Exemplarily, the surrounding cloth cover is made of heat-sealed cloth or printed flannelette.

[0058] Exemplarily, the edge cotton strips are made of white high-elastic sponge. Among them, two edge cotton strips are arranged along the two long sides of the magic cube mattress, with a length of 188 cm, a width of 12 cm, and a height of 5 cm; two edge cotton strips are arranged along the two short sides of the magic cube mattress, with a length of 178 cm, a width of 12 cm, and a height of 5 cm.

[0059] Exemplarily, the edge cloth cover includes two long-side cloth strips and two short-side cloth strips. The two long-side cloth strips are respectively arranged along the long sides of the supporting quilted cotton 1, and the two short-side cloth strips are respectively arranged along the short sides of the supporting quilted cotton 1. The two long-side cloth strips and the two short-side cloth strips are connected end to end and spliced by sewing. The left and right sides of the long-side cloth strips and the left and right sides of the short-side cloth strips are respectively bonded by colorless and odorless glue to form a cavity for accommodating the edge cotton strips.

[0060] Exemplarily, the length of the two long-side cloth strips is 191 cm and the width is 33 cm, and the length of the two short-side cloth strips is 181 cm and the width is 33 cm.

[0061] Exemplarily, as Figure 2 and Figure 3 shown, the bottom of the edge cloth cover is provided with a first connecting part and a second connecting part. The first connecting part extends along the outer circle of the edge cloth cover, and the second connecting part extends along the inner circle of the edge cloth cover. In this embodiment, the supporting quilted cotton 1 is provided with a first sewing part 11 arranged along its peripheral edge and a second sewing part 12 arranged at an interval from the edge. The first connecting part is aligned with the first sewing part 11 and fixedly connected by sewing, and the second connecting part is aligned with the second sewing part 12 and fixedly connected by sewing. Through the design of two sewing lines, the edge structure 2 can be more firmly connected to the supporting quilted cotton 1, avoiding the displacement of the edge cotton strips, thereby also ensuring the structural stability of the accommodating groove 101 and avoiding the displacement of the magic cube module 3.

[0062] Exemplarily, the distance between the first connecting part and the second connecting part is equal to the width of the edge cotton strip to ensure that the outer side of the edge cotton strip is flush with the outer side of the supporting quilted cotton 1. Of course, the length and width dimensions of the supporting quilted cotton 1 are the same as those of the elastic supporting layer 20 to ensure that the outer sides of the whole magic cube mattress are flush.

[0063] In another embodiment, as Figure 4 and Figure 5As shown, a third sewing part 13 is provided on the supporting quilting 1 along its peripheral edge. The second connecting part is aligned with the third sewing part 13 and fixedly connected by sewing. The bottom of the edge cloth cover is adhesively bonded to the elastic support layer 20 by a colorless and odorless glue. In this solution, the edge structure 2 is fixedly connected to both the supporting quilting 1 and the elastic support layer 20 at the same time. While ensuring the connection stability, the size of the supporting quilting 1 is reduced, and the material cost is lowered. Further, the distance between the edge of the supporting quilting 1 and the edge on the same side of the elastic support layer 20 is equal to the width of the edge cotton strip, so as to ensure that the outer side of the edge cotton strip is flush with the outer side of the elastic support layer 20.

[0064] Exemplarily, as Figure 1 shown, a part of the first zipper 51 extends along the outer periphery of the top surface of the edge cloth cover and is connected to the edge cloth cover by sewing. The other part of the first zipper 51 extends along the outer periphery of the bottom surface of the top surface quilting layer 30 and is also connected to the top surface quilting layer 30 by sewing. The starting point and the ending point of the first zipper 51 are both arranged at the head position of the magic cube mattress for the convenience of the user to operate, and at the same time, it is convenient to hide the first zipper 51 through the bed screen to improve the aesthetics.

[0065] Exemplarily, as Figure 1 and Figure 6 shown, the composite support layer 10 further includes a breathable mesh cloth 4 provided on the top of the accommodation groove 101. The breathable mesh cloth 4 is used to cover the magic cube module 3 below to limit the position of the magic cube module 3 in the vertical direction and ensure that the magic cube module 3 in the accommodation groove 101 does not shift during use. At least a partial structure of the breathable mesh cloth 4 is detachably connected to the top of the edge structure 2 to selectively open and close the accommodation groove 101. The breathable mesh cloth 4 has soft supportability and is provided with a plurality of ventilation holes, which can improve the breathability of the magic cube mattress.

[0066] In this embodiment, as Figure 1 and Figure 6 shown, the breathable mesh cloth 4 is connected to the top surface of the edge structure 2 by a second zipper 52. Specifically, a part of the second zipper 52 extends along the inner circumferential part of the top surface of the edge cloth cover and is fixedly sewn to the edge cloth cover. The other part of the second zipper 52 extends along the outer periphery of the breathable mesh cloth 4 and is fixedly sewn to the side edge of the breathable mesh cloth 4. Among the four side edges of the breathable mesh cloth 4, at least three side edges are connected to the edge structure 2 by the second zipper 52 to ensure that the user can conveniently take and place the magic cube module 3.

[0067] In another embodiment, as Figure 7As shown, the composite support layer 10 further includes an elastic band 6. The elastic band 6 is disposed in the accommodation groove 101. The elastic band 6 is composed of elastic elements such as elastic cords. The elastic band 6 has elasticity and can press the lower magic cube module 3 through elastic force, thereby limiting the magic cube module 3 to a preset position within the accommodation groove 101. The user can pull up or remove the elastic band 6 to release the magic cube module 3 below the elastic band 6, facilitating the taking and placing of the magic cube module 3. Specifically, four elastic bands 6 are arranged at intervals along the width direction of the bed. The length of the elastic band 6 is 180 cm and the width is 5 cm. The two ends are respectively connected to the two short sides of the surrounding structure 2. Please refer to Figure 7 , in the order from left to right, the first elastic band 6 is spaced 25 cm from the left inner wall of the accommodation groove 101, the second elastic band 6 is spaced 25 cm from the first elastic band 6, the third elastic band 6 is spaced 50 cm from the second elastic band 6, and the fourth elastic band 6 is spaced 25 cm from the third elastic band 6.

[0068] In another embodiment, as Figure 8 shown, the composite support layer 10 further includes a Velcro component 34. The Velcro component 34 has a Velcro hook surface and a Velcro pile surface. One of the bottom surface of the magic cube module 3 and the support quilting 1 is provided with a Velcro hook surface, and the other is provided with a Velcro pile surface. The magic cube module 3 and the support quilting 1 are detachably connected through the Velcro hook surface and the Velcro pile surface. Further, two Velcro hook surfaces or Velcro pile surfaces extending along the length direction thereof are provided on the bottom surface of the magic cube module 3, and the upper surface of the support quilting 1 is laid with a whole piece of Velcro pile surface or Velcro hook surface. The magic cube module 3 can be quickly and reliably detachably fixed to the support quilting 1 through the Velcro component 34, which is very convenient for the user to disassemble and assemble.

[0069] Exemplarily, as Figure 1 and Figure 6 shown, the magic cube modules 3 are distributed in a matrix in the accommodation groove 101. Specifically, along the width direction of the magic cube mattress, there are two columns of magic cube modules 3 in the accommodation groove 101, corresponding to the use areas of two users respectively. By replacing the magic cube modules 3 in the corresponding areas, independent adjustment of the support softness and hardness between different users can be achieved, avoiding mutual influence. Along the length direction of the magic cube mattress, there are multiple rows of magic cube modules 3 in the accommodation groove 101. The user can flexibly replace the magic cube modules 3 according to different body parts and different heights to adapt to the support softness and hardness requirements of different body parts and different heights of the user.

[0070] Exemplarily, as Figure 8 and Figure 9As shown, the Rubik's Cube module 3 includes a Rubik's Cube inner liner (not shown in the figure) and a Rubik's Cube cloth cover 31. The Rubik's Cube inner liner is set as a square-shaped flexible structure, and the Rubik's Cube cloth cover 31 is sleeved outside the Rubik's Cube inner liner. The Rubik's Cube cloth cover 31 is provided with an openable and closable cloth cover opening. On the one hand, the Rubik's Cube cloth cover 31 wraps the Rubik's Cube inner liner, playing a role in protecting the Rubik's Cube inner liner and improving the aesthetics after opening the Rubik's Cube mattress; on the other hand, the openable and closable setting of the Rubik's Cube cloth cover 31 allows users to replace the Rubik's Cube inner liner with different softness and hardness or damaged ones.

[0071] In this embodiment, as Figure 9 shown, a sealing cloth strip 32 is provided at the position of the cloth cover opening of the Rubik's Cube cloth cover 31. The sealing cloth strip 32 can be attached to or separated from each side of the cloth cover opening after heating to open and close the cloth cover opening. Specifically, the material of the sealing cloth strip 32 is heat-sealing cloth. The length of the sealing cloth strip 32 is 75 cm and the width is 6.5 cm. Use a steam iron at a temperature of 100 - 110°C (preferably 100°C) to iron on the sealing cloth strip 32 to seal the cloth cover opening. When it is necessary to replace the Rubik's Cube inner liner in the Rubik's Cube cloth cover 31, the sealing cloth strip 32 can be torn open multiple times, and then use a steam iron to iron on the sealing cloth strip 32 to seal the cloth cover opening. Moreover, using the sealing cloth strip 32 for sealing will not cause the thickness of the sealing part of the cloth cover opening to increase, resulting in unevenness of the overall structure of the composite support layer 10, and improving the flatness of the Rubik's Cube mattress.

[0072] Preferably, one side of the sealing cloth strip 32 is fixed to the Rubik's Cube cloth cover 31 by sewing, avoiding the loss of the torn sealing cloth strip 32 and eliminating the need to re-align the sealing cloth strip 32 when re-sealing.

[0073] In another embodiment, as Figure 10 shown, a third zipper 33 can also be provided at the cloth cover opening, and the cloth cover opening is opened and closed by the third zipper 33. Preferably, the third zipper 33 is set as an invisible zipper structure to avoid increasing the thickness of the sealing part of the cloth cover opening.

[0074] Exemplarily, the material of the Rubik's Cube inner liner is a bio-based material, specifically it can be bio-based cotton or soy-based polyurethane foam. The materials are natural and environmentally friendly, with the advantage of low allergenicity.

[0075] Exemplarily, the Rubik's Cube module 3 has three support softness and hardness levels: soft, medium, and hard. Correspondingly, the Rubik's Cube inner liner also has three support softness and hardness levels: soft, medium, and hard. By adjusting the preparation process, Rubik's Cube inner liners with different support softness and hardness can be obtained. For example, by adjusting the ratio of polyol to isocyanate and adding functional additives, etc., the hardness of soy-based polyurethane foam can be precisely controlled. Such process adjustments are all prior art content and will not be elaborated here.

[0076] Exemplarily, the material of the Rubik's Cube cloth cover 31 is 3D mesh cloth, which is a three-dimensional mesh material made of high-density polyester fiber through a three-dimensional weaving technique, and has the characteristics of washability, high breathability, high elasticity and compression resistance.

[0077] Exemplarily, as Figure 1 shown, when the Rubik's Cube module 3 is installed in the accommodation groove 101, the width direction of the Rubik's Cube inner liner is arranged along the length direction of the Rubik's Cube mattress. The widths of the Rubik's Cube inner liners of the Rubik's Cube modules 3 with different softness and hardness are different.
