Piuma is one of the most revolutionary and daring products in the evolution of technologies and materials used by Kartell. This is the first time that a material containing carbon fibre has been injection moulded. The seat has a minimum thickness of a few millimetres (2 mm at most) resulting in an ultralight chair (just 2.2 kg). Piuma is very light and very thin, but also incredibly strong, flexible and suitable for outdoor use.
