Description

Technical Field

[0001] This utility model belongs to the field of textile technology, and specifically relates to a support pad. Background Technology

[0002] A mattress is a bedding product placed between the body and the bed to ensure consumers get healthy and comfortable sleep. Compared with adults, children's spines are more flexible and more susceptible to deformation due to external factors. For example, poor sleeping posture or an unsuitable mattress can lead to spinal deformities. Given the dynamic physiological curvature changes of children's spines during growth and development, their healthy development places special demands on the support and fit of the mattress.

[0003] However, commercially available children's mattresses generally have the following defects in terms of structure and function design: (1) Problem of mechanical transition between layers: When a child's weight changes, the mechanical transition between mattress layers is discontinuous, which easily creates a "pressure fault". This causes the shoulders, hips and other parts to be subjected to sinking pressure, while the waist is unsupported, creating a "funnel" effect, which in turn exacerbates the risk of spinal imbalance; (2) Contradiction between breathability and support: Highly breathable materials usually have insufficient support stiffness due to their loose structure; while highly supportive materials have too high density, which hinders air circulation. In a humid and hot environment, this contradiction can cause problems such as sweating and bacterial growth, which have a negative impact on children's sleep health; (3) Limitations of comfort performance: Mattresses that are too soft or too hard will have a negative impact on children. If the mattress is too soft, it may increase the risk of scoliosis. If the mattress is too hard, long-term use will affect sleep comfort. Utility Model Content

[0004] In view of this, the present invention provides a support pad to solve the problems of mechanical transition between layers of children's mattresses, the contradiction between breathability and support, and the limitation of comfort performance.

[0005] To achieve the above solution, the technical solution of this utility model is as follows:

[0006] This utility model provides a support pad, which includes a pad core body. Along the thickness direction, the pad core body includes a moisture-absorbing layer, a silicone sponge layer, and a sponge layer in sequence. The silicone sponge layer has a plurality of openings. Along the direction from the moisture-absorbing layer to the sponge layer, the hardness of each layer gradually increases.

[0007] The principle of this utility model's support pad is as follows: by setting the hardness of each layer to gradually increase along the direction from the moisture-absorbing layer to the sponge layer, a multi-layered progressive gradient hardness structure can be formed, providing stable support for children and avoiding the "funnel" effect caused by the "pressure discontinuity" resulting from the discontinuous mechanical transition between mattress layers; the combination of the silicone sponge layer and the moisture-absorbing layer can effectively absorb sweat generated during sleep, creating a dry sleeping environment, and the porous structure of the silicone sponge layer forms breathable channels, accelerating air circulation, promoting the expulsion of heat and moisture, reducing stuffiness during sleep, improving sleep quality, and ensuring comfort during sleep; the sponge layer ensures the mattress has good elasticity while ensuring the stability of the mattress structure.

[0008] Optionally, the thickness of the moisture-absorbing layer is 0.5-1.5 cm.

[0009] Optionally, the moisture-absorbing layer is made of memory foam or a sponge with a moisture absorption rate greater than 1000%.

[0010] Optionally, the thickness of the silicone sponge layer is 1-3 cm.

[0011] Optionally, the thickness of the sponge layer is 6-8 cm.

[0012] Optionally, the porosity of the silicone sponge layer is 90%-95%.

[0013] Specifically, by setting the porosity of the silicone sponge layer to 90%-95%, this invention can form a highly efficient air-permeable channel, further accelerating air circulation, promoting the expulsion of heat and moisture, reducing stuffiness during sleep, and improving sleep quality.

[0014] Optionally, the sponge layer includes a first layer and a second layer, the first layer being adjacent to the bottom surface of the silicone sponge layer, and the density of the second layer being greater than or equal to 25 kg / m³. 3 The density of the first layer is less than that of the second layer, and the density difference between the second layer and the first layer is 2-5 kg / m³. 3 .

[0015] Specifically, this invention configures the sponge layer to include a first layer and a second layer, wherein the first layer is adjacent to the bottom surface of the silicone sponge layer, and the density of the second layer is greater than or equal to 25 kg / m³. 3 The density of the first layer is less than that of the second layer, and the density difference between the second layer and the first layer is 2-5 kg / m³. 3By using foam of different densities, the foam layer can maintain its elasticity while providing good support, thus avoiding the technical problems that may arise from using a mattress that is too soft, which could increase the risk of scoliosis, and from using a hard mattress for a long time, which could affect sleep comfort.

[0016] Optionally, the support pad further includes a cover for wrapping the pad core body, the cover including a top layer fabric and a bottom layer fabric connected at the surrounding edges, the top layer fabric being adjacent to the top surface of the moisture-absorbing layer, and the bottom layer fabric being adjacent to the bottom surface of the sponge layer.

[0017] Specifically, by adding a cover, this utility model can prevent dust and liquids from seeping into the mattress and inhibit bacteria and mold from invading the mattress pores, thus avoiding the negative impact on health caused by the growth of bacteria, preventing stains from causing the mattress core to age, extending the service life of the mattress core, and maintaining the internal hygiene environment of the mattress.

[0018] Optionally, the top layer fabric is a one-way moisture-wicking fabric, which includes a hydrophilic side and a hydrophobic side, with the hydrophilic side adjacent to the top surface of the moisture-wicking layer.

[0019] Specifically, this invention sets the top layer fabric as a one-way moisture-wicking fabric, which includes a hydrophilic side and a hydrophobic side. The hydrophilic side is positioned adjacent to the top surface of the moisture-absorbing layer. This allows sweat and other substances to diffuse to the hydrophilic side through the hydrophobic side, while the hydrophilic side quickly absorbs and evaporates moisture, blocking reverse penetration and expelling moisture. This keeps the skin surface dry, preventing stuffiness and humidity from affecting sleep quality, thereby improving sleep quality.

[0020] Optionally, the cover further includes a moisture-absorbing wadding, which is located between the top fabric and the moisture-absorbing layer, and is connected to the periphery of the top fabric and the bottom fabric.

[0021] Specifically, this invention adds a moisture-absorbing wadding sheet, which is positioned between the top layer fabric and the moisture-absorbing layer, and is connected to the periphery of the top layer fabric and the bottom layer fabric. This allows the moisture-absorbing wadding sheet to quickly wick away sweat, achieving a quick-drying effect when combined with the one-way moisture-wicking fabric, improving sweat evaporation efficiency, and further enhancing sleep quality.

[0022] Optionally, the bottom surface of the underlying fabric is provided with a number of anti-slip points.

[0023] Specifically, this invention adds several anti-slip points to the bottom surface of the underlying fabric, which can prevent the mattress from slipping during use and improve the user experience.

[0024] Optionally, an opening is provided at at least one edge of the cover, and the opening is provided with an opening and closing member for opening and closing the opening.

[0025] Specifically, this utility model provides an opening at at least one edge of the cover and an opening / closing member for opening and closing the opening. The cover can be opened by the opening / closing member to remove the inner pad core body for cleaning.

[0026] Optionally, the opening and closing element is a zipper, Velcro, button, strap, or magnet. Attached Figure Description

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] It should be noted that all directional indicators (such as up, down, left, right, front, back, top, bottom, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0042] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a direct connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0043] Furthermore, in this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the word "and / or" throughout the text means including three parallel solutions; taking "A and / or B" as an example, it includes solution A, solution B, or a solution that simultaneously satisfies A and B. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0044] The following defects are commonly found in the structural and functional design of commercially available children's mattresses: (1) Problems with interlayer mechanical transition: When a child's weight changes, the mechanical transition between mattress layers is discontinuous, which can easily lead to "pressure gaps". This can cause the shoulders, hips and other parts to be subjected to sinking pressure, while the waist is unsupported, resulting in a "funnel" effect, which in turn exacerbates the risk of spinal imbalance. (2) Contradiction between breathability and support: Highly breathable materials usually have insufficient support stiffness due to their loose structure. Highly supportive materials, on the other hand, have excessive density, which hinders air circulation. In a humid and hot environment, this contradiction can cause problems such as sweating and bacterial growth, which can negatively affect children's sleep health. (3) Limitations in comfort performance: Mattresses that are too soft or too hard can have a negative impact on children. If the mattress is too soft, it may increase the risk of scoliosis. If the mattress is too hard, long-term use will affect sleep comfort.

[0045] Based on the above-mentioned technical problems, one embodiment of this utility model provides a support pad, which includes a core body. Along the thickness direction, the core body sequentially includes a moisture-absorbing layer 1, a silicone sponge layer 2, and a sponge layer 3. The silicone sponge layer 2 has several openings. Along the direction from the moisture-absorbing layer 1 to the sponge layer 3, the hardness of each layer gradually increases. The thickness of the moisture-absorbing layer 1 is 0.5-1.5 cm, and the material of the moisture-absorbing layer 1 is memory foam or sponge with a moisture absorption rate greater than 1000%. The thickness of the silicone sponge layer 2 is 1-3 cm, and the porosity of the silicone sponge layer 2 is 90%-95%. The thickness of the sponge layer 3 is 6-8 cm, and the sponge layer 3 includes a first layer 31 and a second layer 32. The first layer 31 is adjacent to the bottom surface of the silicone sponge layer 2, and the density of the second layer 32 is greater than or equal to 25 kg / m³. 3 The density of the first layer 31 is less than that of the second layer 32, and the density difference between the second layer 32 and the first layer 31 is 2-5 kg / m³. 3 .

[0046] In another embodiment of this utility model, the support pad further includes a cover for wrapping the pad core body. The cover includes a top fabric 4 and a bottom fabric 6 connected at the periphery edges. The top fabric 4 is adjacent to the top surface of the moisture-absorbing layer 1, and the bottom fabric 6 is adjacent to the bottom surface of the sponge layer 3. The top fabric 4 is a one-way moisture-wicking fabric, which includes a hydrophilic side and a hydrophobic side. The hydrophilic side is adjacent to the top surface of the moisture-absorbing layer 1. The bottom surface of the bottom fabric 6 is provided with a plurality of anti-slip points. An opening is provided at at least one edge of the cover, and an opening and closing component is provided at the opening. The opening and closing component is a zipper, Velcro, button, strap, or magnet.

[0047] In another embodiment of the present invention, the cover further includes a moisture-absorbing wadding 5, which is located between the unidirectional moisture-wicking fabric 4 and the moisture-absorbing layer 1, and is connected to the periphery of the top fabric 4 and the bottom fabric 6.

[0048] The present invention will be described in detail below through specific examples and embodiments. It should also be understood that the following embodiments are only for specific illustration of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-essential improvements and adjustments made by those skilled in the art based on the above description of the present invention are within the scope of protection of the present invention. The specific process parameters, etc., in the following examples are merely examples within a suitable range; that is, those skilled in the art can make appropriate selections within the appropriate range based on the description herein, and are not intended to be limited to the specific values ​​in the examples below.

[0049] Example 1

[0050] Please see Figure 1 , Figure 1 This is a schematic diagram of the support pad in this embodiment. The support pad can be used as a mattress, sofa cushion, etc. The support pad includes a core body, which, along its thickness direction, sequentially includes a moisture-absorbing layer 1, a silicone sponge layer 2, and a sponge layer 3. The hardness of each layer gradually increases from the moisture-absorbing layer 1 to the sponge layer 3.

[0051] Please continue reading. Figure 1 The moisture-absorbing layer 1 provides comfort and moisture absorption for children. The thickness of the moisture-absorbing layer 1 is 0.5-1.5 cm, and its material is memory foam or a sponge with a moisture absorption rate greater than 1000%, i.e., highly absorbent sponge. The 12-hour moisture dissipation rate of the moisture-absorbing layer 1 is greater than 75%. The hardness of the moisture-absorbing layer 1 (i.e., the depth of indentation under a load of 4N to 40N) is greater than or equal to 25 mm (4-40N), and the energy storage modulus of the moisture-absorbing layer 1 is 10-30 kPa. Memory foam and highly absorbent sponge are existing technologies and will not be described in detail here.

[0052] Please continue reading. Figure 1 The silicone sponge layer 2, through its inherent open structure, forms breathable channels, accelerating air circulation, promoting the expulsion of heat and moisture, reducing stuffiness during sleep, and improving sleep quality. Simultaneously, the silicone sponge layer 2, combined with the moisture-absorbing layer 1, effectively absorbs sweat generated during sleep, creating a dry sleeping environment and improving sleep quality. The silicone sponge layer 2 has several openings, a thickness of 1-3 cm, and a porosity of 90%-95%. The moisture absorption rate of the silicone sponge layer 2 is 300%-500%. The 12-hour moisture dissipation rate of the silicone sponge layer 2 is greater than 75%. The hardness of the silicone sponge layer 2 (i.e., the depth of indentation under a load of 4N to 40N) is greater than or equal to 25 mm (4-40N), and the storage modulus of the silicone sponge layer 2 is 10-30 kPa. For example, the material of the silicone sponge layer 2 can be silicone sponge, i.e., a sponge-like structure formed by foaming and bursting vulcanization based on raw silicone rubber. Silicone sponge is existing technology and will not be discussed further here.

[0053] Specifically, in this embodiment, by setting the porosity of the silicone sponge layer 2 to 90%-95%, a highly efficient air-permeable channel can be formed, further accelerating air circulation, promoting the expulsion of heat and moisture, reducing stuffiness during sleep, and improving sleep quality. In this embodiment, by setting the moisture absorption rate of the silicone sponge layer 2 to 300%-500%, and using memory foam or a sponge with a moisture absorption rate greater than 1000% (highly absorbent sponge) as the material of the moisture-absorbing layer 1, a moisture absorption difference can be created between the silicone sponge layer 2 and the moisture-absorbing layer 1. The moisture-absorbing layer 1 quickly absorbs sweat, and the moisture-absorbing layer 1 quickly expels the absorbed sweat through the moisture absorption difference between the silicone sponge layer 2 and the moisture-absorbing layer 1.

[0054] Please see Figures 1 to 3 The foam layer 3 is used to ensure the mattress has good elasticity and to ensure the stability of the mattress structure. The foam layer 3 includes a first layer 31 and a second layer 32. The first layer 31 is adjacent to the bottom surface of the silicone foam layer 2. The density of the first layer 31 is less than the density of the second layer 32, and the density of the second layer 32 is greater than or equal to 25 kg / m³. 3 The density difference between the second layer (32) and the first layer is 2-5 kg / m³. 3The moisture absorption rate of the first layer 31 is 1500%-1800%, and the moisture absorption rate of the second layer 32 is 1800%-2000%. The 12-hour moisture dissipation rate of both the first layer 31 and the second layer 32 is greater than 75%. The energy storage modulus of the first layer 31 is 30-50 kPa. The hardness of the second layer 32 is less than or equal to 10 mm (200-250 N), and the energy storage modulus of the second layer 32 is 50-200 kPa. The first layer 31 has multiple first teeth 311, all located on the bottom surface of the first layer 31. The second layer 32 has multiple second teeth 321, all located on the top surface of the second layer 32. The second teeth 321 mesh with the first teeth 311. The first tooth 311 extends along the thickness direction and includes a base 31101 and a crown 31102. The crown 31102 is an arc-shaped protrusion. Longitudinally, the sponge layer 3 is divided into six zones: a first zone 33 to a sixth zone 38. The length of the first zone 33 is 360mm-460mm, the length of the second zone 34 is 150mm-220mm, the length of the third zone 35 is 500-600mm, the length of the fourth zone 36 is 170-250mm, the length of the fifth zone 37 is 120mm-150mm, and the length of the sixth zone 38 is 360mm-460mm. The first zone 33 provides effective support for the head and neck of children under 9 years old (excluding 9 years old), thereby ensuring good comfort of the head and neck during sleep. The second zone 34 provides effective support for the shoulders of children under 9 years old, maintaining the natural curve of the shoulders and avoiding discomfort caused by compression of the shoulder nerves. Zone 35 provides effective support for the hips and legs of children under 9 years old or adults over 9 years old (including those aged 9 and 18). Zone 6 corresponds to the lumbar region of adolescents (over 9 years old), providing sufficient support for the lumbar spine to help maintain its natural curve and prevent deformation. Zone 5 37 provides effective support for the back area of ​​adults over 9 years old, maintaining back comfort in the process. Zone 6 38 provides appropriate support for the head and neck area of ​​adults over 9 years old, maintaining its inherent natural physiological curve and relieving pressure on the head and neck area. When children are 6-9 years old but taller than 145cm, Zones 33, 34, 35, and 36 are matched. Clearly, the support pad in this embodiment is suitable not only for children under 9 years old, but also for teenagers over 9 years old. Children under 9 years old (0-9 years old) are matched with Zone 33, Zone 34, and Zone 35, while teenagers over 9 years old are matched with Zone 35, Zone 36, Zone 37, and Zone 38. As children grow, rotating the direction of the support pad allows it to meet the needs of children in different growth stages.The ratio of the radius of curvature of the lowest point of the base 31101 of the first tooth 311 or the vertex of the crown 32102 of the second tooth 321 located in the fifth zone 37 to the radius of curvature of the vertex of the crown 3102 of the first tooth 31 or the lowest point of the base 32101 of the second tooth 321 (hereinafter referred to as the radius of curvature ratio) is 2.2-2.4; the radius of curvature ratio is 1.5-1.6 in the second zone 34, 0.4-0.5 in the first zone 33, 0.6-1.2 in the third zone 35, 0.9-1.1 in the fourth zone 36, and 0.8-1.2 in the sixth zone 38.

[0055] Specifically, in this embodiment, the sponge layer is configured to include a first layer 31 and a second layer 32. A plurality of first teeth 311 are added to the first layer 31, and a plurality of second teeth 321 that mesh with the first teeth 311 are added to the second layer 32. The density of the second layer 32 is set to be greater than or equal to 25 kg / m³. 3 The density difference between the second layer 32 and the first layer 31 is set to 2-5 kg / m³. 3 This design creates a differentiated density structure along the thickness direction, forming a progressive support system. This avoids the "pressure discontinuity" caused by discontinuous interlayer mechanical transitions in existing technologies, which leads to sinking pressure on areas like the shoulders and hips, while the lower back is left unsupported, exacerbating the risk of spinal imbalance. This embodiment, by setting the radius of curvature ratio in different areas within different ranges, creates a longitudinally differentiated density structure, forming a progressive support system to adapt to the support needs of different parts of a child's body. This reduces local pressure points in areas like the shoulders and hips, relieves muscle tension and pain, promotes deep sleep, and improves sleep quality. Simultaneously, it maintains good elasticity and ensures the overall stability of the support pad. By partitioning the pad and setting the radius of curvature ratio in different areas within different ranges, the support pad can meet the needs of children of different ages, reducing usage costs. Furthermore, by setting the radius of curvature ratio in different areas within different ranges, it improves the fit between the foam pad and the body curves of different parts of children of different ages, providing support and comfort during sleep. In this embodiment, by setting the moisture absorption rate of the first layer 31 to 1500%-1800% and the moisture absorption rate of the second layer 32 to 1800%-2000%, a gradient-increasing moisture absorption dynamic difference can be formed between the silicone sponge layer 2, the first layer 31 and the second layer 32, which can quickly remove the sweat absorbed by the moisture-absorbing layer 1 and provide a comfortable sleeping environment.

[0056] The principle of the support pad in this embodiment is as follows: by setting the hardness of each layer to gradually increase along the direction from the moisture-absorbing layer 1 to the sponge layer 3, the multi-layer progressive gradient hardness structure along the thickness direction can provide stable support for children and avoid the "funnel" effect caused by the "pressure discontinuity" in the mechanical transition between mattress layers; the combination of silicone sponge layer 2 and moisture-absorbing layer 1 can effectively absorb sweat generated during sleep, creating a dry sleeping environment, and the open structure of silicone sponge layer 2 forms breathable channels, accelerating air circulation, promoting the expulsion of heat and moisture, reducing stuffiness during sleep, improving sleep quality, and ensuring comfort during sleep; the sponge layer 3 ensures the mattress has good elasticity while ensuring the stability of the mattress structure.

[0057] Example 2

[0058] Please see Figure 4 , Figure 4 This is a schematic diagram of the support pad structure in this embodiment.

[0059] Please see Figure 4 The difference between this embodiment and Embodiment 1 is that it also includes a cover for wrapping the core body. At least one edge of the cover has an opening (not shown), and the opening is provided with a closure element (not shown) for opening and closing the opening. The closure element can be a zipper, Velcro, button, strap, or magnet. The cover includes a top layer fabric 4 and a bottom layer fabric 6 connected at their surrounding edges. There are no restrictions on the connection method between the top layer fabric 4 and the bottom layer fabric 6; for example, it can be a fixed connection (e.g., quilted connection) or a detachable connection (e.g., a zipper). The top layer fabric 4 is adjacent to the top surface of the moisture-absorbing layer 1, and the bottom layer fabric 6 is adjacent to the bottom surface of the sponge layer 3. The top layer fabric 4 is a one-way moisture-wicking fabric, which includes a hydrophilic side (not shown) and a hydrophobic side (not shown), with the hydrophilic side adjacent to the top surface of the moisture-absorbing layer 1. The unidirectional moisture-wicking fabric uses a double-sided material, meaning the two sides are made of different materials: one side is hydrophilic and the other is hydrophobic. Examples of hydrophilic side materials include porous polyester, porous spandex, and porous nylon, while examples of hydrophobic side materials include ordinary polyester, ordinary spandex, and ordinary nylon. Unidirectional moisture-wicking fabrics are existing technology and will not be elaborated further here. The bottom layer fabric 6 is adjacent to the bottom surface of the sponge layer 3. The bottom surface of the bottom layer fabric 6 has several anti-slip points (not shown), meaning the bottom layer fabric 6 is an anti-slip fabric. There are no restrictions on the material of the bottom layer fabric; it can be cotton fiber, polyester, spandex, nylon, viscose fiber, etc.

[0060] Specifically, this embodiment, by adding a cover, can prevent dust and liquids from seeping into the mattress and inhibit bacteria and mold from invading the mattress pores, avoiding the negative health effects caused by bacterial growth, preventing stains from causing the mattress core to age, thus extending the lifespan of the mattress core and maintaining a hygienic internal environment. This embodiment, by setting the top layer fabric 4 as a one-way moisture-wicking fabric and placing the hydrophilic side of the one-way moisture-wicking fabric adjacent to the top surface of the moisture-absorbing layer 1, allows sweat from the hydrophobic side to diffuse to the hydrophilic side due to the difference in core absorption. The rapid absorption and evaporation of moisture on the hydrophilic side blocks reverse penetration, expelling moisture and keeping the skin surface dry, preventing stuffiness and dampness from affecting sleep quality, thereby improving sleep quality. This embodiment, by adding several anti-slip points to the bottom surface of the bottom layer fabric 6, can prevent the support pad from slipping during use, improving the user experience. This embodiment opens at at least one edge of the cover and adds an opening and closing component at the opening, allowing the cover to be opened and the inner pad core to be removed for cleaning.

[0061] Example 3

[0062] Please see Figure 5 , Figure 5 This is a schematic diagram of the support pad structure in this embodiment.

[0063] Please continue reading. Figure 5 The difference between this embodiment and Embodiment 2 is that the cover also includes a moisture-absorbing wadding 5, which is located between the top fabric 4 and the moisture-absorbing layer 1. The moisture-absorbing wadding 5 is connected to the periphery of the top fabric 4 and the bottom fabric 6. There are no restrictions on the connection method between the moisture-absorbing wadding 5 and the top fabric 4 (made of unidirectional moisture-wicking fabric) and the bottom fabric 6. For example, it can be a fixed connection (e.g., quilted connection) or a detachable connection (e.g., zipper). The material of the moisture-absorbing wadding 5 can be, for example, cellulose acetate, Tencel, etc.

[0064] Specifically, this embodiment adds a moisture-absorbing wadding 5, which is positioned between the top fabric 4 and the moisture-absorbing layer 1. The moisture-absorbing wadding 5 can quickly wick away sweat and, combined with the top fabric 4, achieve a quick-drying effect, improve sweat evaporation efficiency, and further improve sleep quality.
