Pentagon Group's Inner Tube Shelf Unit for Reinhard Müller, 1980s

A rare and iconic masterpiece of Neue Deutsche Design : the Inner Tube Shelf Unit , also known as “Chambre à Air” , designed by Reinhard Müller for the avant-garde Pentagon Group in the 1980s.

This sculptural piece unites the raw aesthetic of industrial materials with a refined composition. A slender steel frame is monumentally framed by a continuous black rubber inner band, which presents the transparent shelves as floating elements. The result is a radical dialogue between brutalism, functionality, and poetry .

The Chambre à Air transcends its role as a piece of furniture: it is a statement piece that is considered a museum collector's item worldwide. The design has been shown numerous times in exhibitions of German postmodernist design and is offered only in the most select galleries specializing in international avant-garde design.

This example is in exceptionally good condition – a unique opportunity to acquire a tangible testament to the creative and experimental core of the 1980s.
