A collapsible support article having a bi-directional corrugated structure is defined by folding along folds lines in an accordion style resulting in peak and valley rows with first and second connections points being defined along the folds lines to generate a second direction of the structure. The first connection points are connected at each peak or valley and each second connection point is connected to adjacent peak or valley rows to define the structural unit. The material used as well as spacing between connection points and the distance between the fold lines determine the strength of and the visibility through the structural unit. The structural unit may be used as a single unit for packing material, as a travel pillow or a plurality of joined structural units to define a sleep suit. Variations in the structural unit may result in a curved support article or a contoured support article.
