A green 'Pastille' ('pastil' or 'Gyro') fiberglass chair designed by Eero Aarnio in 1968 for Asko, Finland, manufactured in Mid-Century in late 1960s or early 1970s.
Pastil was often referred to as the "Gyro" chair as its rocking motion swivels in 360 degrees.
There is also an orange 'Pastille' chair and an orange 'Kantarelli' table from Eero Aarnio available (please see images).
One year after he had designed the pastil chair in 1968 Eero Aarnio received the American Industrial award for this chair. The New York Times wrote about the ball chair and pastil chair at this time: "the most comfortable forms to hold up the human body", and the Conran's Design Dictionary says "they look like essays in period style, perhaps from Barbarella".
