The chair is one of the most revolutionary and enterprising products in Kartell’s repertoire of technology and materials. It took three years of intensive research to settle on the unusual blend needed to create Piuma’s basic design: a carbon-filled thermoplastic polymer compound that gives the structure greater mechanical rigidity and a lower weight. This is a compound that comes from completely different sectors of the industry - automotive and aeronautics - and was therefore completely unprecedented in the world of furnishings. By applying its injection moulding techniques in a sophisticated new way that was designed especially for this material, an exclusive in the world of industrial design, Kartell has managed to create a chair that measures just a few millimetres thick (2 mm max), resulting in an ultra-light product (barely 2.2 kg). It is the first time that a material containing carbon fibre has been injection moulded, and for an aesthetic, stylish product at that. Thanks to this unprecedented mix of materials, the Piuma is not only extremely light and slender but also incredibly durable, flexible, suitable for outdoor use and foldable.
