This iconic Plia folding chair was designed by Giancarlo Piretti and produced by Castelli in the 1970s. The chair features a chrome plated metal frame and a transparent acrylic glass seat and backrest, which creates a unique visual effect that almost makes the chair appear to be floating in space. The Plia chair is not only aesthetically pleasing but also functional, as it can be easily folded for compact storage when not in use. This chair has become a design classic and is now highly sought after by collectors and design enthusiasts. Signed in the frame, as shown in photos. Each chair remains in very good vintage condition, with only minor signs of wear consistent with age and use. Overall, this is a stunning piece that would make a great addition to any modern home or office. I have official proof of authenticity such as vintage catalogs, designer records, or other literature sources and take full responsibility for any authenticity issues arising from misattribution
