Sledge project represents a concept that derives from the nature and embodies the very philosophy of growthin nature, so the whole idea has the sustainable character. Its main shape is gained throughout the series ofcalculations using the Grasshopper software and is defined through connections of the ellipsoid profiles in order that final look should correspond to the philosophy of its main influence like branching of a tree. The object is divided in two parts: the constructional part made of wood and the textile seat that tightens the structure. Dynamics and flow of the wooden construction is provided by its joints that connect the legs with the upper part where the most distinctive part is definitely the spine itself. The textile - sitting part is done in a perforated material in order to reveal its construction beneath so that the final look leaves the expression of elegance and transparency.
