The basic fabric layer orients toward the direction of the coverage layer, pressing and embedding into the covering layer and constituting a fabric surface laminating material.
The so-called pressing and embedding the basic fabric layer into the covering layer is, by pressing the basic fabric layer and the covering layer, the uneven surface of the basic fabric layer having fibers directly or indirectly pressing the covering layer via glues, so that the surface of the covering layer generating a certain degree of concavity, and thus composing a more stable pressing result.
The inflatable middle layer 105 can be fixedly connected to the upper layer structure 101 on a first surface of the inflatable middle layer by the drawstrings 106, and fixedly connected to the bottom layer structure 102 on a second surface of the inflatable middle layer.

Another approach is to integrate the inflation pump and the inflatable middle layer 105, providing an inflation power by plug-in or other ways. The inflatable middle layer 105 comprises at least one air chamber configured to provide a predetermined shape after expansion during the inflation. In practical manufacturing, more than two air chambers can be designed, these air chambers maintain certain independence even by the corresponding mechanism (such as a unidirectional valve), so that another air chamber still can maintain a certain supporting force when an air chamber is under leakage. In addition, if the mattress is designed to be used by two people, the air chamber corresponding to the mattress can be designed to have a buffer space between the two sets. By this way, even a first user lying on one side turns over, a second user sleeping on the other side will not be directly affected by excessive vibrations. The buffer layer can be constituted by vibration isolated materials in itself such as an air chamber with lower pressure or sponges, etc. Or, the gases between the two sets of air chambers do not connected with each other, so as to generate an effect similar to the independent cylinder of the conventional mattresses.
In addition, the periphery of the inflatable middle layer 105 has a surrounding side drawstring 103. The side surrounding sheet outstretches a surrounding three-layer structure by at least one side drawstring. The side drawstring can be plastic materials, fabric fiber materials or other connection materials which can provide a certain tension and supporting forces. by ways of high frequency welding or paste ...etc., the side surrounding sheet 103 is connected to other portions of the inflatable mattress 10, so as to maintain the inflatable mattress 10 to keep a predetermined shape during inflation.

The side drawstring can be plastic materials, fabric fiber materials or other connection materials which can provide a certain tension and supporting forces. by ways of high frequency welding or paste, etc., the side surrounding sheet 113 is connected to other portions of the inflatable mattress 11, so as to maintain the inflatable mattress 11 to keep a predetermined shape during inflation.
In other words, the inflatable middle layers 105, 115 can be constituted by various kinds of different structures. Besides, since the top surface portion of the upper layer structures 105, 115 are main parts in touch with users, therefore, the top surface portion can include structures constituted by the fabric surface laminating materials, so that the fabric surface laminating materials oriented toward users are constituted by fabric surfaces. Of course, based on considerations of factors on designs and convenience of manufacturing ...etc., this kind of fabric surface laminating materials can also extend to the whole upper layer structures 101, 111, or even extend to the side surrounding sheets 103, 113. If one hopes the mattresses can be designed to be used on two side, the bottom layer structures 102, 112 can be directly designed to be the same as the design of the upper layer structures 101, 111.
