The Arco floor lamp from Flos is one the great design classics and is as popular today as it was in 1962 when it was designed by Achille & Pier Castiglioni. The floor lamp is like a sculpture in the room due to its size and massive base in marble. Arco looks great by a sofa, dining room table, or conference table. The arc curve is adjustable and the lamp head can be rotated.
