The "Crystal Chiavari" from OC Designs is manufactured from four patented injection molding processes, yielding a virtually completely clear chair, the manufacturer says. The chair, which features an adjustable flexing backrest, weighs 9 pounds and supports up to 400 pounds. The chair is scratch- and stain-resistant and offers nonskid, non-marking feet. Stainless steel, chrome-plated and nickel-plated versions are also available, as are cushions and chair covers.
