         5 . The inflatable product as claimed in  claim 2 , further comprising an auxiliary portion and a connecting element, wherein the auxiliary portion is provided next to where the edges are connected, and is held by the connecting element. 
     
     
         6 . The inflatable product as claimed in  claim 1 , wherein the edges comprise convex portions which are connected to each other. 
     
     
         7 . The inflatable product as claimed in  claim 6 , wherein the inflatable product is an air mattress, and the external wall is a corner wall of the air mattress. 
     
     
         8 . The inflatable product as claimed in  claim 1 , wherein the parts have different colors and/or different embossing. 
     
     
         9 . The inflatable product as claimed in  claim 1 , wherein the parts are strip-shaped, the edges of the strip-shaped parts comprise lateral edges and end edges, the lateral edges of the strip-shaped parts comprise convex portions and concave portions which are alternately arranged, and the strip-shaped parts are disposed in a symmetrical arrangement with the convex portions connected to each other and the concave portions connected to each other. 
     
     
         10 . The inflatable product as claimed in  claim 9 , wherein the inflatable product is an air mattress, and the concave portions are connected to form side walls of the air mattress. 
     
     
         11 . The inflatable product as claimed in  claim 9 , wherein the inflatable product is an air mattress, and the convex portions are connected to form corner walls of the air mattress. 
     
     
         12 . The inflatable product as claimed in  claim 1 , wherein the parts are strip-shaped, the edges of the strip-shaped parts comprise lateral edges and end edges, the lateral edges of the strip-shaped parts comprise convex portions and straight portions which are alternately arranged, and the stripe-shaped parts are disposed in a symmetrical arrangement with the convex portions connected to each other and the straight portions connected to each other. 
     
     
         13 . The inflatable product as claimed in  claim 12 , wherein the inflatable product is an air mattress, and the straight portions are connected to form side walls of the air mattress. 
     
     
         14 . The inflatable product as claimed in  claim 12 , wherein the inflatable product is an air mattress, and the convex portions are connected to form corner walls of the air mattress. 
     
     
         15 . The inflatable product as claimed in  claim 1 , wherein the inflatable product is an air mattress and further comprises a top wall and a bottom wall, the parts are strip-shaped, the edges of the strip-shaped parts comprise lateral edges and end edges, the lateral edges of the strip-shaped parts comprise concave portions connected to the top wall and the bottom wall. 
     
     
         16 . The inflatable product as claimed in  claim 1 , wherein the parts are strip-shaped, the edges of the strip-shaped parts comprise lateral edges and end edges, the end edges comprise convex portions, and the end edges of the strip-shaped parts are connected to each other. 
     
     
         17 . The inflatable product as claimed in  claim 16 , wherein the inflatable product is an air mattress, and the end edges of the strip-shaped parts are connected to form corner walls of the air mattress. 
     
     
         18 . The inflatable product as claimed in  claim 1 , wherein the external wall is a continuous-unity wall. 
     
     
         19 . A method of producing an inflatable product, comprising:
 providing a first sheet and a second sheet;   connecting the first sheet and the second sheet by fusion or adhesive to form a connecting line thereon wherein the connecting line is not straight;   spreading a part of the first sheet and second sheet that is disposed at a side of the connecting line, to form an external wall of the inflatable product.   
     
     
         20 . The method as claimed in  claim 19 , further comprising removing another part of the first sheet and second sheet that is disposed at another side of the connecting line. 
     
     
         21 . A method of producing an inflatable product, comprising:
 connecting different portions of a sheet by fusion or adhesive to form a plurality of parallel connecting lines thereon, wherein each of the connecting lines are not straight;   spreading out the fused sheet to form an external wall of the inflatable product.   
     
     
         22 . The method as claimed in  claim 21 , further comprising cutting the fused sheet into a plurality of sections after the connecting lines are formed, wherein each of the sections has one connecting line thereon. 
     
     
         23 . An inflatable product comprising:
 a first portion having a first desired shape;   a second portion having a second desired shape;   wherein the inflatable product has reduced material at the first portion, to limit expansion of the first portion when the inflatable product is inflated, thereby preventing the first portion from deviating from the first desired shape;   wherein the inflatable product further has increased material at the second portion, allowing the second portion to expand more when the inflatable product is inflated, thereby preventing the second portion from deviating from the second desired shape.
