Cheap, light-weight, portable, waterproof, stackable, easy to clean, plastic patio chair, manufactured from one (ca. 2 kilogram) piece of polypropylene in a single process - The Monobloc Plastic Chair.
The first all-plastic chair was designed by the italian designer Joe Volombo in 1965. It was made in 5 pieces - the backrest /seat monococque and 4 single legs.
Then, in 1967 the first monobloc chair was invented. ‘Selene’ by the italian designer Vico Magistretti, made from just a single piece of 3 mm thick reglar (fiberglass-reinforced polyester). Magistretti resolved the technical difficulties associated with the strenght of the legs by configuring them in an 'S' shape.
At the same time, another structural one-piece plastic chair was developed by danish designer Verner Panton. It was a cantilever chair (with no rear legs) made of luran-s plastic (acrylate-styrene - acrylonitrile) and could be produced only in 1970s
with the development of injection- molding technology.
The very first mass-produced monoblocs probably came from the french Allibert Group or the US Grossfillex Group.
Millions have been produced since their debut in the early 1980s. Every 70 seconds a monobloc chair comes out from a single press. 220 °C hot polypropylene is mashed through the extruder into a mold. There are only fractions of a millimeter
slack between the two halfs of the mold that endure a pressure of 1.000 tons.
Early anonymous monoblocs cost around $60 each, but as more and more were manufactured, the price dropped to less than $3. They are manufactured in Russia, Taiwan, Australia, Mexico, The United States, Italy, France, Germany, Marocco, Turkey, Israel and China, among other countries.
Monoblocs are a universally accessible, mass-manufactured object, landfill sites are stuffed with them, and millions more are on their way.
Design proliferation

Since then many new monoblocs have been added, designed by the well known protagonists of the international design scene: Ross Lovegrove, Karim Rashid,
Jasper Morrison, and Philippe Starck to name but a few.
