Monobloc (chair)
Encyclopedia
The Monobloc chair is a lightweight stackable polypropylene
chair, often described as the world's most common.
Based on original designs by the Italian designer Vico Magistretti
in 1967, variants of the one-piece plastic chair went into production with Allibert Group and Grossfillex Group in the 1970s. Since then, millions have been manufactured in countries including Russia, Taiwan, Australia, Mexico, the United States, Italy, France, Germany, Morocco, Turkey, Israel and China. Many design variants of the basic idea exist.
The Monobloc chair is named because it is injection moulded from thermoplastic
polypropylene
, the granules being heated to about 220 degrees Celsius, and the melt injected into a mold. The gate of the mould is usually located in the seat, so ensuring smooth flow to all parts of the tool. The chairs cost approximately $3 to produce, making them affordable across the world.
