The design challenge was to constructed a chair that supports the weight of an adult using only one 4’ by 8’ sheet of corrugated plastic and two instances of additional fasteners (staples, small spots of glue, nuts and bolts, etc.).
With a few carefully measured folds, scores, and cuts I had a functional architecture-inspired chair. It sits on two triangular columns that intersect each other with finger joints. The only additional fasteners I used were a couple of patches of hot glue to hold up the seat’s side braces. So far, it’s easily held the weight of any adult who’s sat in it.
