A sleek, modern and weather-resistant take on classic wicker. The seat and back of the Orso Outdoor Armchair - Set of 4 by Oxford Garden are made using a specialty synthetic wicker made of touch, moisture resistant polyethylene resin. The rustic texture of the seat is balanced by the clean, minimalist lines of the tubular aluminum frame. The aluminum has a powder coated finish that helps make it even more durable for year-round use around an outdoor dining table.
