Care

• Frame: Dust regularly with a dry microfiber cloth, and wipe away smudges using a soft cloth slightly dampened with warm water and mild soap before drying immediately. Avoid steel wool, abrasive pads, or harsh chemical cleaners, as these can scratch or dull the metal's protective finish.
• Upholstery: Vacuum gently on low power using a soft brush attachment, brushing in the natural direction of the pile to maintain its plush texture. Blot liquid spills immediately with a dry, white cloth without rubbing to avoid crushing the delicate fibers, and keep out of direct sunlight to preserve the rich green color.
