THE DESIGN | FEATURES AT A GLANCE | DIMENSIONS | ORDER WITH CONFIDENCE The Design Harry Bertoia's 1950 experiment with bending metal rods into practical art produced a revered collection of seating, including the Diamond Lounge Chair. Innovative, comfortable and strikingly handsome, the chair’s delicate filigree appearance belies its strength and durability. In Bertoia’s own words, “If you look at these chairs, they are mainly made of air, like sculpture. Space passes through them.” The chair is offered with a full cover in dozens of fabrics and its generous size provides extra room for lounging.
