Arco Floor Lamp

Achille Castiglioni and Pier Giacomo Castiglioni, Flos

The Castiglioni brothers designed the Arco in 1962 around a simple problem: how to bring overhead light to a table without touching the ceiling. Their answer was a two-metre arc of stainless steel balanced by a block of Carrara marble heavy enough to hold it steady.

Why Estate & Design selected it

The Arco is one of the rare designs that solved its problem so completely that nothing has replaced it. It lights a dining table, a reading chair or a whole corner of a room, and the marble base has become a sculptural object in its own right. Sixty years on, it still looks inevitable.
