2005-2010 / corrugated cardboard, chipboard, cardboard tubes
My first cantilevered cardboard chair was very structurally conservative, as I wasn't sure if the concept would work. It is composed of five layers that become bulkier towards the center, to support more weight. The layers are then friction-fitted together around cardboard tubes that come at the center of big rolls of paper for architectural plotters.
The second cardboard cantilever is also quite structurally conservative, using thick strips of cardboard, threaded rods, and a hard paper-mache shell to unify the layers. After applying several layers of paper-mache, the surface was sanded smooth, polyurethaned, and waxed to achieve a finish similar to burnished leather.
The third cardboard cantilever was made to address all the shortcomings of the previous two, as well as tackle a new challenge: making a jig system so that the chair could be reproduced multiple times. Making multiples also required a cheaper glue, so this chair is held together entirely with wheat paste, costing cents on the gallon. This chair uses much thinner structure than the previous two, while dispensing with the threaded rods and cardboard tubes used to tie the layers together, which are unnecessary when laminated with a clamping jig.
