As Kartell celebrates its 15th year anniversary, the renowned European designer Philippe Starck comes up with the largest single mould polycarbonate sofa which he calls as Uncle Jack. According to a Design Boom article, the sofa gives emphasis to the most unbelievable sample of this outstanding technology. And this leads to a seat surface that has a measurement of 190cm and weight of 30 kilograms done all in one polycarbonate piece. The entire range also includes the armchair called Uncle Jim and the smaller type of armchair called Uncle Jo done in a similar material. This is one collection of armchairs that offers a high sense of mixed minimalism and advanced technology.
