Integrated and continuous system of seats and tables for university lecture rooms and conference halls, designed and created using new-concept structural layouts, which simplify assembly operations by allowing a wide range of compositional possibilities. Rows are assembled in a continuous form that is made to measure, following precise design requirements: in a straight line, curved or S-shaped composition, on horizontal flooring or on large steps. In overcoming the limitations associated with modularity, it allows a continuous shape without gaps characterised by fluid horizontal lines, ideal for a uniform and comfortable study or work environment.
