The Story Behind

Originally designed in 1962 by renowned Polish designer Józef Chierowski, the 366 Armchair is a true icon of mid-century modern furniture. While its wooden version became a beloved classic, the metal edition was never produced… until now.

At 366 Concept, we’ve revived this forgotten design, staying true to its original aesthetic while enhancing it with a modern, minimalist twist. The 366 Metal Armchair is lightweight, durable, and crafted for exceptional comfort. Whether you're looking for a designer lounge armchair, or a mid-century modern accent piece, the 366 Metal Armchair is an elegant choice. Its timeless appeal, high-quality craftsmanship, and mid-century charm make it ideal for homes, offices, and boutique spaces.

IN DETAIL

Fabric: your choice

This piece is made to order, so the fabric is yours to choose. More than ninety are available across four wood finishes – from soft bouclés and deep velvets to flat, hard-wearing weaves — each chosen to sit well with the frame and to age gently in a room that's lived in.

Whatever you lean toward – warm neutrals, a muted colour, a bit more texture – there's a version of this design that will feel settled in your space. If you'd like to be sure of the colour and the feel before deciding, order a few swatches and see them in your own light.

IN DETAIL

Frame: Structure in Black

A matte, powder-coated metal frame redraws the silhouette. What was once wood becomes steel – lighter in form, sharper in character, just as enduring. The industrial precision of the frame meets the softness of the upholstery, and the conversation between the two is what gives each piece its edge. From lofts to lobbies, it reads the room.

Józef Chierowski

An architect by training and a piano designer by secondary trade, Józef Chierowski (1927–2007) divided his career between the Lower Silesian Furniture Factory in Świebodzice and the Academy of Fine Arts in Wrocław, where he headed the Industrial Design Department.

In 1962, when fire destroyed much of the factory, the need for simple, efficient furniture gave Chierowski the opening he had long sought. His 366 Armchair went into immediate production and over two decades became one of the most ubiquitous pieces of furniture in Poland, with over half a million units sold. 366 Concept has held exclusive reissue rights from the Chierowski family since 2014.
