June 30, 2017andy gregg Chair #2, June 1991. Aluminum rims lashed together with butyl inner-tubes, and assembled using only scissors and a hacksaw. The tensioned rubber and flexible backrest made for bouncy comfort. It lived outside, and the direct sunlight disintegrated the inner-tubes within a few months. #backtothelab #innertube #bikefurniture #prototype #designprogress A post shared by Andy Gregg (@bikefurniture) on Jun 30, 2017 at 6:57am PDT
