Abstract
The present disclosure relates to an inflatable structure transformable between a deflated state and an inflated state. The inflatable structure comprises a drop stitch fabric having a first layer and a second layer tethered by drop stitches. The inflatable structure is provided with one or more folding lines defining the inflatable structure into two or more interconnected chambers, the one or more folding lines comprising coupling means coupling the first layer to the second layer. Dimensions of the one or more folding lines and/or coupling means are adapted to enable the inflatable structure to in both the deflated state and the inflated state be foldable along the one or more folding lines. The disclosure also relates to a method for manufacturing a foldable inflatable structure in accordance with the foregoing.
