Vintage folding chairs made of authentic 70s polycarbonate

Giancarlo Piretti's Plia for Castelli remains one of the greatest revolutions in furniture design: this folding chair, created in 1967, embodies the perfection of Italian functional minimalism. This set of six original examples, produced between the late 1970s and early 1980s, bears witness to the evolution of early transparent polycarbonates, with their characteristic honey patina. Beyond their utilitarian function, these chairs are masterpieces of modern design, still fully functional despite the marks of their extensive use.

“Plia” chair by Giancarlo Piretti, produced by Anonima Castelli (then Castelli/ICF).

The Plia was designed in 1967 and has become an icon of Italian design for:
– the innovative use of transparent polycarbonate
– the very compact closing mechanism
– visual lightness

This is an original Castelli production, evident in the engravings and not on a sticker. Even the fonts evoke the late 70s and very early 80s.

They are in excellent condition, considering their age and intensive use, with perfectly functional mechanisms and virtually intact tubular structures.

The polycarbonate seat and backrest exhibit the typical honey-colored yellowing characteristic of early polycarbonates, which were still relatively unstable and therefore prone to yellowing due to UV exposure. This is not a defect but, if you will, an additional mark of authenticity. Never polished, never bleached.

Two (2) chairs are missing parts. One is missing a small piece of grease (gommino), the second is missing all four pieces of gum (gommino).

One chair has a chip in the backrest.
A chair has a crack in the seat.

All the chairs show signs of age; the plastic has scratches, probably from trouser rivets. However, these are normal signs that occur regularly on all polycarbonate chairs.
