The investigation of formal and visual aspects recalls to the teaching of design back to the beginning of the XX century and it still proves to be a subject of endless interest before the constant updating in the field of practice and teaching of design. Within the scope of furniture design in Brazil, a great deal of attention was drawn to biographies or to the historical context of some icons. It is not possible to say the same when it comes to the exercise of learning the aspects of materiality itself. Taking into account the underlying concepts of lightness such as shape and visuality, the present work aims at reapproaching a renowned kind of home furniture manufactured in Brazil from the 50s on, through the tension amongst certain cultural, social and technical references, as well as techniques on images of lightness in the modernity and an exercise of analysis of its formal and visual aspects in eight pre-selected samples. The general goal of this work is to highlight a formal and visual repertory, which has been incorporated in the typology of design of the pieces of furniture approached hereby. Other aspects here approached are the systematization and synthesis of the formal and visual aspects within the peculiarities of furniture on a whole, as well as the tridimensional space, which can be either used in the practical field and for the teaching of design.
