Take a look at the chair you’re sitting in. What’s it made out of? Was it manufactured locally? Chances are, it’s constructed from a mix of materials that have a lengthy supply chain spanning much of the globe. Not so with the chairs made by Chairigami, a one-person company founded by recent Yale graduate Zach Rotholz. Chairigami’s furniture is made from local materials (near the company headquarters of New Haven, Connecticut), recyclable, lightweight, flat-packed, and easy to assemble. It’s also made entirely out of thick, triple-wall cardboard.
