The ‘On and On’ collection of lightweight and extremely durable chairs and stools is the result of a collaboration between American furniture manufacturer Emeco and London-based designers Barber & Osgerby. The chairs and stools are manufactured from 70% rPET (waste plastic bottles), 10% non-toxic pigment, and 20% glass fibre for strength; furthermore Emeco aims to recycle used chairs to manufacture new ones. The chairs are suitable for interior and exterior use and can be stacked up to six chairs high. Photo by David Brook Shoot Studio. Emeco
