Its organic shape and the opening at the bottom of the backrest reflect the spirit of the Evolution chair (designed by Ora-Ito for Zanotta in 2007). Eva perfectly illustrates the work of Ora-Ito: sober and futuristic lines, a universal and timeless style able to weather time whilst remaining elegant. The rounded shell is made of polyurethane fully reinforced by a steel insert. Its rounded and ergonomic shapes guarantee optimum comfort. The central mast and the swivel base are made of varnished steel.
