THONET Stool • B 9 Ha Series
The bentwood technique perfected by Michael Thonet was one of the inspirations for Marcel Breuer's experiments with bent tubular steel. This idea gave rise to the four-part B 9 nesting table set. The small tables can be used in many ways – as a side table in seating groups, as a practical surface, or as the perfect spot for a vase of fresh flowers. After use, they can be pushed into one another to save space. What sets this series apart is its functional simplicity – the nesting tables consist solely of chrome-plated, bent tubular steel and rectangular tops. During his time at the Bauhaus, Marcel Breuer experimented with steel and tubular steel, a promising material that was new to furniture-making at the time. Close collaboration with the aircraft manufacturer Junkers in Dessau accelerated the development process. Among his first designs were the B 9 nesting tables as well as various shelves and side furniture. The Thonet card catalogue of 1930/31 already included the complete range. Breuer originally designed the B 9 nesting tables for the canteen of the Bauhaus building in Dessau. The versatile little tables were also used in the student apartments and the Masters' Houses of Walter Gropius.
The B 9 Ha is the stool of the series. It has the format of the smallest nesting table, the B 9 a, but stands on a sturdier frame made of 22 mm tubular steel. The top is a 20 mm thick MDF panel measuring 34.5 x 34 cm. POM plastic glides or felt glides are included. The surface is finished in Beech I; ash and gloss lacquer finishes are available at an additional cost, as is a powder-coated frame. At 45 cm high, the stool weighs 4 kg.
