The sitscape is a system that provides a customised seating landscape. The sitscape is configured based on preferred positions of use and the dimensions of the users.As a „customized mass product” it allows different demands and forms within the same structural principle. The first version of this furniture piece was realised in a length of six meters for a client in Berlin.The form extends the usual use of a couch. The design is based on specific seating positions and smooth transformations between them. The preferred relaxing positions of the client are used to generate a “perfect fit” in the sitscape and provide familiar possibilities for relaxing. The transitional areas between these positions are undetermined in their use. They of fer new and unexpected possibilities, which can be discovered and appropriated by the users.The sitscape is one metre wide and “infinitely” long. This organizational system has a simple construction principle of vertical sections connected by metal elements which allow the configuration of dif ferent forms within this system. The sitscape will be sold by the “metre” and the costumers have the choice of various positions which can be combined in any sequence.The main structural elements are the sections, which are digitally cut out of laminated wood or composite material. The connecting structure consists of aluminium spacers between the sections and metal thread rods that go through the sections.The rods are tightened by wing nuts and give the structural stability. Diagonal tension wires are spanned through the inner void of the sections and give the stability against the torsion forces. The most visible form generating elements take the main vertical loads while the hidden metal elements give the support for the horizontal and torsion forces. The sitscape therefore is in one direction massive and in the other direction light and almost dissolved.The upholstery consists of a system of cushions that can be connected in multiple ways to cover the favourite zones of the sitscape temporary or permanently.
