With no visible hardware, the Piana Chair designed by David Chipperfield is a sleek take on the functional folding chair.

Piana is a folding chair made out of polypropylene reinforced with glass fibre. The chair has a synchronized opening and closing system that rotates around a single axis. This finely engineered mechanism is concealed within the moulded components. The matt finish and tactile qualities of the polypropylene render the chair both comfortable and robust. It folds completely flat and is stackable both vertically and horizontally. The visual language of the object is a simple statement about its function and role, giving the chair a timeless quality.
