1. An inflatable structure, comprising:

  • two fabric bodies, wherein each fabric body has an inner surface and an outer surface;

    a solvent-based hydrophilic and vapor-transmissible plastic layer applied over the inner surfaces of the fabric body;

    a low-modulus hydrophilic and vapor-transmissible plastic layer provided over the solvent-based hydrophilic and vapor-transmissible plastic layer;

    a low-melting-point hydrophilic and vapor-transmissible plastic layer provided over the low-modulus hydrophilic and vapor-transmissible plastic layer;

    wherein once all the layers are applied onto the inner surfaces of the fabric bodies, the inner surfaces of the fabric bodies are bonded together to form at least one continuous S-shaped bonding channel and an inflatable space is formed and enclosed by the S-shaped bonding channels, and areas on the outer surface at two opposite sides of the fabric bodies are bonded together to limit an inflated overall thickness of the fabric body, and the S-shaped bonding channel is formed at two ends with a closed circular bonding line each; and

    an inflating valve provided on the fabric body to communicate with the inflatable space, so that air is supplied into or released from the inflatable space via the inflating valve;
