Sean Yu and Yi-ting Cheng began 22™ in 2005 with a desire to create items in both metal and concrete. Inspired by Japanese architect Tadao Ando, the duo set out to rethink ways to use such an industrial material like concrete to make everyday items like clocks and pens.
"Stitching Concrete is a project, inspired by the contrasts of the Material Concrete Canvas. These stools are made by folding fabric that’s impregnated with cement then drenching it in water. It consists of cement layered between fabric and a PVC backing. Once soaked it can be manipulated for a few hours before hardening. A wooden mould supports it while drying within 24 hours. Before that the edges have been stitched together with brightly coloured thread.
