An innovative offering from Harry Bertoia's Wire Furniture collection, recognized worldwide as one of the great achievements of 20th-century furniture design. An ingenious work of art and craftsmanship, the Diamond Lounge Chair by Knoll is an elegant blend of comfort and visual appeal. Welded steel rods form a diamond-shaped, mesh-like seat that gives a springy feel. Hidden mono-filament and metal hooks help the seat pad and cover attach directly to the frame. Glides on the steel sled base prevent damage to flooring.
