Polypropylene Chairs
Introduction
The monobloc chair (sometimes called Monobloc) is a particular type of chair made of polypropylene, very light and easy to stack. The first records of the monobloc chair date back to 1967, as the creation of Italian designer Vico Magistretti, inspired by a design by architect Joe Colombo. Variants of the one-piece plastic chair entered production made by Allibert Group and Grosfillex Group in the 1970s. Since then, millions have been manufactured in countries such as Russia, Taiwan, Australia, Mexico, United States, Italy, France, Germany, Morocco, Argentina, Turkey, Israel and China. There are many design variations of the basic idea[2]
.
The monobloc chair has this name because it is injection molded from thermoplastic polypropylene. The granules are heated to about 220 degrees Celsius, and the molten plastic is injected into a mold. The mold door is normally located in the seat, to ensure smooth flow of all parts of the tool. The chairs cost around US$3 to produce, making them accessible worldwide.[3].
Social theorist Ethan Zuckerman describes them as having acquired global omnipresence:
