[0025] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0026] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0027] Reference Figures 1 to 3 As shown, this utility model embodiment provides an environmentally friendly glue-free mattress, which mainly includes a first quilted layer 1, a spring support layer 2, a filling comfort layer 3, a second quilted layer 5, and a side panel fabric 6.

[0028] The first quilted layer 1 includes at least a first fabric layer 11, which is located on top of the mattress; the spring support layer 2 is located below the first quilted layer 1 and is the main support structure of the mattress. When a person lies on the mattress, the spring support layer 2 can elastically deform according to the weight and sleeping posture of the body, distribute body pressure, provide even support, maintain the natural curve of the body, and reduce the pressure on various parts of the body.

[0029] The comfort layer 3 is located between the first quilted layer 1 and the spring support layer 2, and the comfort layer 3 is covered with a fabric cover. The material of the comfort layer 3 can provide a soft touch, further cushion body pressure, and increase sleep comfort.

[0030] The second quilted layer 5 is located at the bottom of the mattress and is connected to the spring support layer 2 (in practical applications, an overlay can be placed over the spring support layer 2, and the overlay can be sewn together with the fabric of the second quilted layer 5). It includes at least one second face fabric layer 51. At least one side panel fabric 6 is provided and positioned around the perimeter of the mattress to wrap the first quilted layer 1, the spring support layer 2, the comfort filling layer 3, and the second quilted layer 5. The overlay fabric is connected to the side panel fabric 6 via a first connector, and to the first quilted layer 1 via a second connector. The overlay fabric not only protects the comfort filling layer 3 but also, through its connection with the first quilted layer 1 and the side panel fabric 6, fixes the position of the comfort filling layer 3, ensuring its even distribution within the mattress. It should be noted that, for added stability, the spring support layer 2 and the comfort filling layer 3 can also be connected via a zipper, or by placing an overlay fabric over the spring support layer 2 and sewing it together with the overlay fabric of the comfort filling layer 3.

[0031] In summary, the overall structure of this mattress is as follows: the first quilted layer 1 is located at the top of the mattress, the second quilted layer 5 is located at the bottom of the mattress, and the side panel fabric 6 is placed around the outside of the mattress (the side panel fabric 6 can be a single piece, wrapped around the outside of the mattress; in some practical applications, such as...). Figure 1 As shown, there are two side panels 6, located at the two corners of the mattress perimeter. They together wrap around the spring support layer 2 and the filling comfort layer 3.

[0032] The outer fabric is connected to the side panel fabric 6 via a first connector and to the first quilted layer 1 via a second connector. This connection method firmly fixes the various parts of the mattress together to form a whole, preventing relative displacement between the layers and ensuring the stability of the mattress. It also avoids the problem of using glue during mattress assembly, avoiding the release of harmful substances such as formaldehyde, which may be released by glue, thus reducing indoor air pollution and providing users with a healthy and environmentally friendly environment.

[0033] It should be noted that quilting is a fabric processing technique that uses long needles to sew together layered textiles, securing the filling such as cotton wadding. It typically involves sewing several layers of fabric together with needle and thread, effectively combining fabrics of different materials and thicknesses into a single unit.

[0034] In some practical applications, the first connector is configured as a lining, meaning the outer fabric is quilted onto the outer fabric via the lining. The second connector is configured as a zipper, meaning the outer fabric is connected to the first quilted layer 1 via the zipper. The zipper allows the first quilted layer 1 to be removable for easy replacement or cleaning.

[0035] In other practical applications, the second connector is configured as a non-woven fabric and a zipper. The non-woven fabric is connected to the outer fabric (usually via quilting, with the non-woven fabric sandwiched between the outer fabric and the first quilted layer). The zipper is positioned on both the non-woven fabric and the first quilted layer 1 to connect them. The non-woven fabric acts as a cushioning element, reducing wear and tear that might occur from direct contact between the zipper and the outer fabric. The zipper, located on both the non-woven fabric and the first quilted layer 1, allows for easy connection and disassembly of the first quilted layer 1.

[0036] In some practical applications, the spring support layer 2 can adopt at least the following two structures.

[0037] Reference Figure 2As shown, the first structure of the spring support layer 2 includes a plurality of Bonnell springs 21 arranged in a matrix, and a frame structure formed around the periphery of the plurality of Bonnell springs 21. This frame structure is formed by a plurality of first independent pocket springs 22 arranged in a specific pattern. The plurality of Bonnell springs 21 are connected by spiral threading. Each first independent pocket spring 22 corresponds to one Bonnell spring 21 and is fixedly connected to it by a pin.

[0038] The Bonnell springs 21 are arranged in a matrix and form the main supporting force of the spring support layer 2. When a person lies on the mattress, each Bonnell spring 21 will undergo corresponding elastic deformation according to the pressure applied to different parts of the body, distributing body weight and providing basic support. They are connected by spiral threads, which not only stabilize each Bonnell spring 21 but also allow the Bonnell springs 21 to distribute pressure more evenly when under stress, avoiding excessive local pressure.

[0039] The frame structure is formed by a series of first independent pocket springs 22 arranged around the outer periphery of the Bonnell springs 21. Each first independent pocket spring 22 corresponds to one Bonnell spring 21 and is fixedly connected by pry bar studs. This design allows the frame structure to be tightly integrated with the internal Bonnell springs 21, enhancing overall stability. At the edge of the mattress, the first independent pocket springs 22 can provide additional support to prevent sagging when a person sits or lies on the edge of the mattress, ensuring the support performance of the mattress edge.

[0040] When the human body applies pressure to the mattress, the pressure first acts on the first quilted layer 1 and the comfort filling layer 3, and then is transmitted to the spring support layer 2. The Bonnell springs 21 and the first independent pocket springs 22 work together to distribute the pressure throughout the spring support layer 2. Due to the connection structure between the springs, the pressure can be transferred and dispersed between them, allowing all parts of the mattress surface to bear pressure evenly, providing more comfortable support for the human body.

[0041] Reference Figure 3 As shown, the second structure of the spring support layer 2: The spring support layer 2 is formed by a rectangular arrangement of several second independent pocket springs 23, with adjacent second independent pocket springs 23 arranged diagonally and forming an intersection point (e.g., Figure 3 As shown in the enlarged view, in the square area formed by four adjacent second independent pocket springs 23, the four second independent pocket springs 23 are connected at an intersection point, forming a unique four-leaf clover-like shape. Each intersection point is connected by ultrasonic welding. This connection method eliminates the need for glue, making it more environmentally friendly and cost-effective. Furthermore, its intersecting arrangement results in more and tighter connection points than a typical rectangular horizontal and vertical arrangement, leading to higher connection stability.

[0042] Each second independent pocket spring 23 is individually encapsulated, allowing it to compress and rebound independently according to the pressure from different parts of the body when a person lies on the mattress. Adjacent second independent pocket springs 23 are arranged diagonally and connected at the intersection points via ultrasonic welding. When one spring is under pressure, the connection at the intersection points transfers some of the pressure to adjacent springs, further dispersing the pressure and enhancing the stability and integrity of the entire spring support layer 2. Furthermore, the ultrasonic welding connection at the intersection points is very strong, ensuring long-term stability of the connection between the springs. Compared to traditional glue connections, ultrasonic welding improves the environmental friendliness of the spring support layer 2.

[0043] It should be noted that, based on the structure of any of the aforementioned spring support layers 2, a 7-10 cm thick sponge frame (not specifically shown in the figure) is formed around the perimeter of the spring support layer 2. The soft texture of the sponge frame provides a more comfortable feel when a person touches the edge of the mattress, avoiding the harshness that may result from direct contact with the spring support layer 2.

[0044] In some practical applications, the first quilted layer 1 also includes a first non-adhesive cotton layer 12 and a mesh fabric 13 stacked sequentially below the first face fabric layer 11. The first non-adhesive cotton layer is configured as non-adhesive silk floss or sponge. The first face fabric layer 11, the first non-adhesive cotton layer and the mesh fabric 13 are quilted together, and the first quilted layer 1 is quilted together with the side face fabric 6.

[0045] The first fabric layer 11 is in direct contact with the human body. The first non-adhesive cotton layer (non-adhesive silk floss or sponge) beneath it has good elasticity and softness, further cushioning body pressure and increasing sleep comfort. The mesh fabric 13 enhances structural stability. The three layers are connected as a whole by quilting. The first quilted layer 1 is quilted to the side panel fabric 6, ensuring a tight bond between the first quilted layer 1 and the outer structure of the mattress. This helps transfer the pressure exerted by the body on the first quilted layer 1 to the side panel fabric 6 and the entire mattress structure, ensuring the overall stability of the mattress.

[0046] In some practical applications, the second quilted layer 5 also includes a second non-adhesive cotton layer 52 located above the second face fabric layer 51. This second non-adhesive cotton layer is configured as non-adhesive silk floss or sponge. The second face fabric layer 51 and the second non-adhesive face layer are quilted together, and the second quilted layer 5 is quilted together with the side panel face fabric 6. The second face fabric layer 51 is located at the bottom of the mattress, and the second non-adhesive cotton layer (non-adhesive silk floss or sponge) above it provides additional cushioning and support for the mattress. When the mattress is placed on the bed frame, the second non-adhesive cotton layer can reduce friction and impact between the spring support layer 2 and the bed frame, protecting the internal structure of the spring support layer 2.

[0047] The second quilted layer 5 is quilted together with the side panel fabric 6, further strengthening the connection between the bottom of the mattress and the outer perimeter.

[0048] In some practical applications, the comfort filling layer 3 is configured as a 3D air core, cotton felt, or several mini springs, which can be selected according to the actual situation.

[0049] 3D Air Core: Offers excellent breathability and elasticity. Air circulates freely within the 3D air core structure, carrying away heat and moisture generated by the body, keeping the mattress dry and comfortable. Simultaneously, its elasticity provides support and cushioning.

[0050] Cotton felt: Soft in texture, providing a comfortable feel. Cotton felt has good moisture absorption, which can absorb the sweat excreted by the body, making the sleeping environment more comfortable.

[0051] Mini springs: Each mini spring can extend and retract independently, adapting to the pressure on different parts of the body to provide more precise support. Multiple mini springs combined together can distribute pressure, enhancing the support and comfort of the comfort layer 3.

[0052] In summary, a layer of cotton felt can also be added above and below the spring support layer 2, mainly for sound insulation, to reduce the noise generated by the spring support layer 2 during deformation.

[0053] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
