In making this stool, you will be producing an unconventional yet efficient building material with both insulation and thermal mass properties. Made up of hemp hurd, lime, and a binder material, hempcrete (as a single material) is a natural and carbon negative alternative to the abundant layers of insulation, drywall, cladding, etc… that cover the walls of our homes today. In some ways, the simple instructions for this stool are the same as instructions for building a wall of your home with this material. More on hempcrete here. The simple assembly process takes up to 1 hour to complete.

The Two by Two Chair ambitiously utilizes a webbing system to form its seating surfaces. The builder is required to stretch and nail in each strap so that there is no slack when the chair is complete. Its shape is reminiscent of Rietveld chair designs, but it makes some ergonomic concessions learned from more modern chairs, where the back support cradles ones lower back with minimal pressure. The full assembly process takes a little over 3 hours to complete and the parts cost 50 USD on average.

Featured in the essay Make This Chair., the Two by One Chair design was used as a pretext to pursue a discussion on DIY and the modern condition. It requires a minimal amount of materials by utilizing the triangle to both enhance the structure of the chair and define its aesthetic (much in the same way Enzo Mari and Tord Boontje did with their DIY designs). The full assembly process takes about 2 hours to complete and the parts cost less than 20 USD on average.
