The cover 3 and armrest covers 4 are then connected via a first connecting part 301 and a second connecting part 401 to ensure structural stability. Users can use the inflatable mattress 1 alone or combine the inflatable armrests 2 with the inflatable mattress 1 to form a comfortable sofa bed for lying or sitting, especially in outdoor environments, providing a convenient rest option, adapting to various scenarios, and improving user comfort. The first air chamber 101 is provided with a plurality of fabric filaments 102. The two ends of the fabric filaments 102 are connected to the top and bottom of the first air chamber 101, respectively. After the first air chamber 101 is filled with air, the fabric filaments 102 play a role in restricting the shape of the first air chamber 101. A sufficient number of fabric filaments 102 can enable the air mattress 1 to withstand greater air pressure, thereby giving the air mattress 1 a better support effect, making the user more stable and comfortable when lying or sitting on the air mattress 1, and improving the quality of rest.

[0034] In a further embodiment of this invention, the bed cover 3 has a first opening, a first connecting part 301 is provided at the first opening, a flexible connector 402 is provided at the lower part of the armrest cover 4, a second connecting part 401 is provided at the outer edge of the flexible connector 402, and the flexible connector 402 covers the first opening.

[0035] In this embodiment, the bed cover 3 has a first opening, and the lower part of the armrest 4 is provided with a flexible connector 402.

[0037] In this embodiment, the armrest cover 4 has a second opening 403. During assembly, the inflatable armrest 2 is placed into the armrest cover 4 through the second opening 403, and then the second opening 403 is closed and the inflatable armrest 2 is inflated, so that the inflatable armrest 2 fits tightly into the inside of the armrest cover 4, forming a stable support structure, ensuring that the inflatable armrest 2 is not easily displaced when the user is using it, and providing more stable armrest support.

[0038] In a further embodiment of this invention, both the first connecting part 301 and the second connecting part 401 are zipper connecting parts.

[0039] In this embodiment, the first connecting part 301 and the second connecting part 401 adopt a zipper design, which makes it easy for users to connect and separate quickly and conveniently, further improving assembly efficiency.

[0040] In a further embodiment of this invention, the backrest 202 and the two armrests 203 cooperate to form an I-shaped structure. The backrest 202 is located in the middle of the air mattress 1, and the armrests 203 are symmetrically arranged on both sides of the backrest 202 to form a double-sided sitting support surface.

[0041] In this embodiment, the I-shaped structure design of the armrest 203 and backrest 202 forms a stable support after inflation. The backrest 202 can be leaned against by the user, providing comfortable back support, while the armrest 203 provides arm support. The inflatable armrest 2 combined with the inflatable mattress 1 forms a sofa structure, improving the user experience. After connecting the inflatable armrest 2 to the inflatable mattress 1, the backrest 202 is located in the middle of the inflatable mattress 1, and the armrests 203 are symmetrically arranged on both sides of the backrest 202, forming a double-sided seating support surface. This allows people to sit on both sides of the backrest 202, increasing usable space, meeting the needs of multiple people using it simultaneously, and improving the utilization rate of the bed. In addition, it also provides better support, avoiding tilting or collapse caused by uneven force on one side, ensuring safety during use.

[0042] In a further embodiment of this invention, the air mattress 1 includes an upper film layer 103, an upper base fabric 104, a lower film layer 105, a lower base fabric 106, and side panels 107. The upper film layer 103 is connected to the upper base fabric 104 by adhesive bonding, and the lower film layer 105 is connected to the lower base fabric 106 by adhesive bonding. The two ends of the fabric filament 102 are respectively connected to the upper base fabric 104 and the lower base fabric 106. The upper edge of the side panel 107 is connected to the upper film layer 103 by high-frequency welding, hot melting, or adhesive bonding, and the lower edge of the side panel 107 is fixedly connected to the lower film layer 105 by high-frequency welding, hot melting, or adhesive bonding. The upper film layer 103, the side panel 107, and the lower film layer 105 cooperate to form the first air chamber 101.

[0043] In this embodiment, the upper film layer 103 and the upper base fabric 104 form the upper part of the first inflation cavity 101, and the lower film layer 105 and the lower base fabric 106 form the lower part of the first inflation cavity 101. During production and processing, the upper base fabric 104 and the lower base fabric 106 are first connected together by the fabric drawing 102, and then the upper film layer 103 and the lower film layer 105 are glued to the upper base fabric 104 and the lower base fabric 106, which facilitates manufacturing. The main body also includes a side panel 107, which connects the upper film layer 103 and the lower film layer 105. The upper film layer 103, the lower film layer 105, and the side panel 107 cooperate to form the first air chamber 101. The width of the side panel 107 corresponds to the length of the fabric filament 102. If the upper film layer 103 and the lower film layer 105 are directly connected, the connection part of the upper film layer 103 and the lower film layer 105 will be subjected to a large tensile force and is easily damaged. However, by using the side panel 107 and the fabric filament 102 to limit the overall thickness of the air mattress 1 when fully inflated, the air mattress 1 can withstand greater air pressure, thereby providing better support and greater comfort.

[0044] In a further embodiment of this invention, the air mattress 1 is provided with a first inflation / deflation valve 108, which is connected to the first inflation chamber 101, and the air armrest 2 is provided with a second inflation / deflation valve 204, which is connected to the second inflation chamber 201.

[0045] In this embodiment, the air mattress 1 is equipped with a first inflation / deflation valve 108, which is connected to the first inflation chamber 101. The user can inflate or deflate the first inflation chamber 101 using the first inflation / deflation valve 108, improving ease of use. Simultaneously, the user can adjust the gas pressure within the first inflation chamber 101 using the first inflation / deflation valve 108, thereby adjusting the firmness of the air mattress 1 and solving the problem of traditional mattresses not being able to adjust firmness. Similarly, the user can inflate or deflate the second inflation chamber 201 using the second inflation / deflation valve 204 to adjust its pressure, thereby adjusting the firmness of the inflatable armrest 2 and solving the problem of traditional armrests not being able to adjust firmness. This improves both ease of use and comfort.

[0046] In a further embodiment of this example, the bed cover 3 is provided with a first inflation / deflation opening 302, the position of which corresponds to the position of the first inflation / deflation valve 108, and the armrest cover 4 is provided with a second inflation / deflation opening 404, the position of which corresponds to the position of the second inflation / deflation valve 204.

[0047] In this embodiment, the position of the first inflation / deflation opening 302 corresponds to the position of the first inflation / deflation valve 108. During inflation, the user can quickly locate and operate the first inflation / deflation valve 108 through the first inflation / deflation opening 302. The position of the second inflation / deflation opening 404 corresponds to the position of the second inflation / deflation valve 204. Similarly, the user can quickly locate and operate the second inflation / deflation valve 204 through the second inflation / deflation opening 404. This design allows the user to directly adjust the firmness of the air mattress 1 and the armrests without removing the mattress cover 3 and armrest covers 4, greatly improving the ease of operation and user experience, and ensuring the comfort and flexibility of use.

[0048] In a further embodiment of this invention, the armrest 4 is also provided with a handle 405.

[0049] In this embodiment, the armrest 4 is also provided with a handle 405. During assembly, the armrest 4 and the inflatable armrest 2 can be placed on the inflatable mattress 1 of the bed cover 3 through the handle 405, and the user can easily adjust the position of the armrest 4 relative to the bed cover 3 to ensure that the first connecting part 301 and the second connecting part 401 are aligned, thereby facilitating the user to quickly connect the inflatable mattress 1 and the armrest, improving assembly efficiency. In addition, after assembly, the user can adjust the position of the inflatable sofa bed through the handle 405, further improving ease of use.

[0050] Example 2, see Figure 6The only difference between this embodiment 2 and embodiment 1 is that the backrest 202 and the two armrests 203 cooperate to form an I-shaped structure, and the backrest 202 is located near the edge of the air mattress 1.

[0051] In this embodiment, the backrest 202 is located near the edge of the air mattress 1, and together with the armrest 203, it forms a single-sided sitting support structure, which is suitable for single beds and allows users to use it flexibly in a limited space. The backrest 202 and the two armrests 203 work together to form an I-shaped structure, which enhances the backrest support and improves comfort and stability.
