The 366 Armchair with the metal frame and legs was a secret project of Józef Chierowski with an extraordinary history that never entered industrial production due to the lack of steel. The project was discovered decades later and turned into reality by 366 Concept. 60 years after the original sketch was created, we introduced this design icon to our portfolio.

This previously unknown project – the 366 Metal Armchair – combines the Mid-Century Modern and Art Deco styles. It fits modern, minimalist interiors, but it also works great in elegant and eclectic spaces. The metal finishes are available in various colors – black, matt and glossy brass – that will make this remarkable piece of furniture a true gem in any interior.
