The inflatable sofa is mainly a split combination structure, a total of back, cushion, left support armrest, right support armrest and other four parts, its surface are waterproof and wear-resistant PVC new material, the inner is filled with wire drawing material, through the three-dimensional preparation technology will be the first PVC wear-resistant layer, polyethylene fiber, the second PVC wear-resistant layer connected as a whole. Different from the traditional gluing method, it greatly improves the pressure resistance of the product, making the pressure resistance of the product increased to 20PSI, solving the defects of difficult alignment and easy dislocation in the past, and the binding force of the X-shaped wire drawing unit is higher, further improving the stability of the product structure, and its single-piece structure is easier to store, convenient to carry. Taking into account the water entertainment and land camping two ways of play, to a greater extent to improve the use of products.
