Abstract: The present invention provides for construction of a variety of useful objects including chairs and ottomans from multiple polymers or high density polyethylene (HDPE) by utilizing a living hinge; the hinge comprising a single contiguous sheet of stock, the stock having some material removed rendering the sheet flexible and pliable; wherein some material removed forms a mesh or matrix; wherein the mesh or matrix has been optimized to allow for pliability while eliminating points of excessive stress; wherein the single contiguous sheet is bent in a predetermined shape; the single contiguous sheet relaxing into that predetermined shape over time; and wherein the bent shape retains flexibility under load and while returning to its predetermined shape when no longer under load.
