The Story Behind

The 366 Armchair, an icon of Polish design, was designed in 1962 by Józef Chierowski. Its production was resumed in 2014 by 366 Concept under an exclusive licence. Thanks to new technology, we have hidden the screws connecting the seat, in line with the designer's vision from 50 years ago.

In its new form, it has been featured in global exhibitions, including at The Design Museum in London in 2016 for the exhibition “The Pan-European Living Room”, designed by acclaimed architectural firm OMA, and has won awards such as Must Have at the Łódź Design Festival.

IN DETAIL

Fabric: VELVET

The VELVET collection is synonymous with refinement and softness. Velvet has delighted since its arrival in Europe, providing a royal feel.

This highly tactile fabric, available in a soft color palette, fits a broad range of interiors, adding a touch of sophistication to any home. The fabric’s special stain resistant coating makes it easy to clean.

IN DETAIL

Wood: OAK

Oak wood is one of the highest quality woods with a beautiful decorative surface. The grain has a uniform structure, in which the annual rings are visible. Therefore oak wood is preferred in the construction of noble solid wood furniture. It is prized in furniture making because of its durability, workability and natural beauty.

Józef Chierowski: The Creator

Józef Chierowski, without the exaggeration, is considered the father of our brand. Our name, 366 Concept, comes from his iconic creation: the 366 Armchair. The practical, lightweight and compact furniture furnished millions of Polish homes and countless cafes and offices, becoming the most recognizable Polish design of the mid-20th century.

Chierowski, a renowned interior architect and designer, worked for the Lower Silesian Furniture Factory and taught at the National Academy of Arts in Wrocław. Among his many designs, including the notable VAR Chair, his greatest achievement remains the 366 Armchair, a true icon of Polish Mid-Century Design and a beloved piece of the 1950s and 60s.
