Sito. Structural purity.

As early as the 1920s, Mart Stam, Ludwig Mies van der Rohe and MarcelBreuer had pursued the principle of a flexible cantilever chair manufacturer and subse- quently developed the first steel tube cantilever models. Since that time,the market has seen many a variation on the theme in different materials,with seat and back shells, and frames with stretch material. With the Sito range, the wiege Building design Studio has brought the classic form of the steel tube cantilever chair to a new interpretation and refined the principle of ahighly flexible structure.The constructional principle of Sito was derived from home bridge building:themain structure comprises an elegant tubular frame tensioned by can- tilevered flat steel braces. Distributing forces over the braces allowed the cross section of the primary tubular structure to be reduced and elasticitytobe increased. A flexible, ergonomically designed seat home platform is fittedinto this “triangle of forces”; at the front the seat appears to float over the horizontal tubing and at the back it is screw-fitted onto the braces. The flex of the frame in combination with the pliable seat platform provides a high degree of seated comfort with minimal upholstery thickness. The sameapplies to the viscoelastic backrest that is connected between the verticalextensions of the cantilever braces.The result of the design process is a new, multi-purpose cantilever chairwhich may stand alone or be combined with other Wilkhahn office chairand architectural table ranges. A chair that re-defines the typical ultra lightness ofcantilever models and presents a minimal appearance whilst ensuring spaciousness and seated comfort. A chair that is innovative and distinct without denying its traditional cantilever character.
