Harry Bertoia designed five wire pieces that became known as the Bertoia Collection for Knoll. Among these was the famous diamond chair, a fluid, sculptural form made from a welded lattice work of steel. In Bertoia's own words, 'If you look at these chairs, they are mainly made of air, like sculpture. Space passes right through them'.
Designing often necessitates considering the aesthetic, functional, economic and sociopolitical dimensions of both the design object and design process. It may involve considerable research, thought, modeling, interactive adjustment, and re-design.
