The spring body 140 is composed of multiple vertical springs 141, which are hollowed out to allow the needle body and connector 220 to pass through, ensuring that the connector 220 passes through the seat body 100.

[0056] In traditional manufacturing, workers need to cut the foam sheets according to the size of the seat cushion. By splicing the foam sheets together, the lower part of the seat cushion is wrapped around it, thereby reducing the foreign body sensation caused by the internal support base to the user.

[0057] Reference Figure 2 , Figure 3 and Figure 4 As shown, the sofa provided in this embodiment of the utility model is formed into a bag body 130 by sewing the quilted fabric. After the lower end of the spring body 140 is directly placed into the bag body 130, the bag body 130 can cover the lower end of the spring body 140, which can effectively reduce the foreign body sensation caused by the spring body 140 to the user, effectively simplify the production process, and improve the production efficiency of the sofa.

[0058] Reference Figure 2 , Figure 3 and Figure 4As shown, compared to traditional sofas that use wood as the supporting base, the sofa provided in this embodiment of the utility model uses a spring body 140 as the supporting base, which makes the sofa have a high compression ratio, allowing the sofa to be compressed into a smaller volume for transportation, thereby reducing transportation costs.

[0059] Reference Figure 1 , Figure 2 and Figure 3 As shown, it is understood that the sofa also includes two wear-resistant plates, one of which is sandwiched between the lower end of the spring body 140 and the bottom wall of the pocket body 130, thereby improving the connection stability between the spring body 140 and the pocket body 130 and helping to reduce the mutual slippage between the lower end of the spring body 140 and the bottom wall of the pocket body 130.

[0060] Reference Figure 1 , Figure 2 and Figure 3 As shown, another wear-resistant sheet is connected between the upper end of the spring body 140 and the pad to improve the connection stability between the spring body 140 and the pad. This helps to reduce the mutual slippage between the upper end of the spring body 140 and the pad. In addition, the wear-resistant sheet has wear-resistant physical properties, which can effectively reduce the risk of material powdering after long-term use, thereby improving the durability of the sofa.

[0061] Reference Figure 1 , Figure 2 and Figure 3 As shown, specifically, the wear-resistant sheet can be a blend of polyester fiber and fiber, as well as various materials with high wear resistance.

[0062] Reference Figure 1 , Figure 2 and Figure 3 As shown, it is understood that the seat body 100 also includes a seating sponge, which is laid on the upper end of the wear-resistant sheet on the upper end of the spring body 140. The seating sponge is used to improve the seating feel of the sofa and enhance the user's comfort.

[0063] Reference Figure 2 , Figure 3 and Figure 4 As shown, the pad includes an upper piece 123, a middle piece 122, and a lower piece 121 arranged sequentially from top to bottom. The upper surface of the spring body 140 is planar and has a sitting area and a backrest area. The lower piece 121 covers the sitting area and the backrest area. The lower piece 121 covers the seating foam, and the backrest body 110 is connected to the lower piece 121 and located above the backrest area. The backrest body 110 can be made of high-density foam, thereby providing strong support for the user's hands or back.

[0064] Reference Figure 2 , Figure 3 and Figure 4As shown, the middle piece 122 and the upper piece 123 are sequentially connected to the lower piece 121 and are located above the seating area. The outer edges of the upper piece 123 and the lower piece 121 are both located outside the outer edge of the middle piece 122. That is, the area of ​​the middle piece 122 is smaller than the area of ​​the upper piece 123 and the lower piece 121, so that a gap is formed between the outer edge of the upper piece 123 and the outer edge of the lower piece 121. When the upper piece 123, the middle piece 122 and the lower piece 121 are pressed together, the outer edge of the upper piece 123 has a downward curvature, thereby improving the comfort of the user's legs in contact with the edge of the seat 120.

The backrest 110 includes multiple cushioning pads arranged around the backrest 143, and multiple second cushioning pads arranged around the backrest 143. That is, the spring body 140 can not only serve as a supporting base for the seat 120, but also extend upwards to serve as a built-in supporting base for the backrest 110. The cushioning pads are used to block the foreign body sensation caused by the second springs to the user. The sofa provided in this embodiment of the invention, through the structural arrangement of the spring body 140, allows the spring body 140 to extend into the interior of the backrest 110, thereby providing strong support for the user's hands and back.

[0068] It should be understood that in some other embodiments, the sofa also includes a second pull strip, which is connected to the inner surface of the cover and is embedded at the junction of two adjacent backrests 110. The second pull strip is connected to a plurality of connectors 220 and a plurality of fasteners.
