Our name comes from our flagship product – the 366 Armchair. It was the most popular piece of Polish mid-century furniture. This was partly a matter of luck: in the early 1960s, one of the biggest furniture factories in Poland was destroyed by fire, creating a sudden need for simple furniture that could be assembled quickly.

Young interior and piano(!) designer, lecturer at University of Art in Wrocław, Józef Chierowski jumped at the opportunity. That was when the chair’s potential first manifested itself. Thanks to its minimalist design and lightweight wooden construction, it was an instant success, soon to be found in almost every office, café and restaurant in Poland.

The 366 Armchair was manufactured for over 20 years, with more than 500,000 copies sold throughout the Eastern Bloc. Despite such success, this masterpiece never had the chance to be noticed outside of the Soviet sphere of influence.

In 2014, following a hiatus of over 30 years, 366 Concept decided its time has come. After securing exclusive licensing rights, we reissued this forgotten icon of Polish mid-century design, based on the original drawings from the 60s.
