The F.C 03 chair is part of the collection Formas Curvas. It’s described as “a redefinition of upholstery through the use of only sleeves and knots”. FC only needs two pieces of foam cut in right angles, and a neoprene sleeve for each, closed with only one straight seam, to give shape to function around a metal frame. All cuts are in right angle being very little leftover resulting from formalistic decisions. A self developed upholstery method that requires no screw, bolts, glue, wood or any other kind of mechanical or chemical connector in order to achieve function. A simplistic approach to this vernacular knowledge where the properties of the involved materials are used to their best without the need of hidden structures or capricious cuts.
