An internal tensioning structure for use in an inflatable product fulfills the basic function of maintaining two adjacent inflatable surfaces in a desired geometric arrangement when the inflatable product is pressurized. The tensioning structure is formed by connecting a pair of plastic strips sheets via spaced-apart strands, such as strings or wires. When pulled taut, the strands provide a high tensile strength between the two opposed plastic strips. At the same time, the plastic strips facilitate a strong, long-lasting weld between the tensioning structure and the inflatable product.

A device comprises a first seal member, a second seal member, a first circuit member, a second circuit member and one or more compressive members. The first seal member has a first outer portion having a first seal portion, and a first inner portion located inward of the first outer portion. The second seal member has a second outer portion having a second seal portion, and a second inner portion located inward of the second outer portion. The first seal portion and the second seal portion are bonded together. The first circuit member and the second circuit member are shut in a closed space which is enclosed by the first inner portion and the second inner portion. One of the compressive members is located between the first seal member and the first circuit member or located between the second seal member and the second circuit member.
