In a world dominated by consumer society, supported by a wide range of products that arise every day, and the growing of environmental concern, not only by governments but also by societies, we must ask ourselves if these objects satisfy the sustainability criteria. In view of this concern comes the theme of this thesis: Sustainable Furniture Design. This theme result from a constant search to provide different forms of final disposal of used furniture. The objective is to understand how reuse allows the extension of product useful lifetime and try finding methods that contribute to the creation of eco-furniture. It is important to understand, though, how our attitudes affect the ecosystem in order to create solutions that allow furniture products as environmentally friendly.
