Cassina
1987
Bull was Frattini's last project for Cassina. The collection included sofas and armchairs that adopted an updated concept of ergonomics. When presenting Bull, Frattini said: "Even though very slowly, our way of sitting, both in the intimacy of our homes and in the company of friends, has changed... the back, which seeks support in the point where the seat joins the backrest, must have a rounded, inviting angle of its own."
