The PIANA folding chair has been designed for Alessi by David Chipperfield and is produced by Lamm. It is made of polypropylene reinforced with fiberglass, making it durable enough for outdoor usage, yet measures only 7 centimeters when folded. The matte finish and tactile qualities of the polypropylene render the chair both comfortable and robust; six different colors make it versatile. PIANA is also 100 percent recyclable.
