1. An inflatable product including:
a first sheet made of weldable plastic;
a second sheet made of weldable plastic, the first and second sheets cooperating to define an inflatable chamber;
a plurality of tensioning structures, each tensioning structure including a weldable plastic, a first portion of each of the tensioning structures being welded to the first sheet and a second portion of each of the tensioning structures being welded to the second sheet, wherein the first portion of each tensioning structure includes a first pair of weld strips welded to the first sheet and the second portion of each tensioning structure includes a second pair of weld strips welded to the second sheet, a plurality of strands extend between the first portion of each tensioning structure and the second portion of each tensioning structure, a first portion of the plurality of strands are positioned between the first pair of weld strips of the first portion of each tensioning structure and a second portion of the plurality of strands are positioned between the second pair of weld strips of the second portion of each tensioning structure, the first portion of the plurality of strands are offset from the second portion of the plurality of strands such that a contour of the second portion of each tensioning structure includes a protrusion matching a structure of the first portion of each tensioning structure that is recessed and the structure that is recessed of the first portion of each tensioning structure is positioned between the first portion of the plurality of strands positioned between the first pair of weld strips of the first portion of each tensioning structure; and
a plurality of isolating members positioned in the inflatable chamber, the isolating members being positionable to isolate the first portions of the tensioning structures from the second portions of the tensioning structures to block all weldable contact between the first and second portions, the plurality of isolating members remaining positioned inside the inflatable chamber together with the plurality of tensioning structures.
