"TamTam", an assembly stool, was created in 1968 in the city Nurieux of eastern France by Henry Massonet, a manager of a plastic material molding factory at the time. The product is characterized by its simple design with the percussion instrument that is also the name of the brand as a motif. At the time, the product was used as a simple stool for fishing and had poor sales. However, after a magazine published an article with a photograph of the French actress Brigitte Bardot using the stool, the product gained much public attention.

In 1973, due to the effects of the oil shock, manufacturing this product temporarily became extremely difficult. However, by keeping in mind their philosophy for reasonable prices and practicality, the started selling more and more products as time went on. While the product later gains spotlight as a designer furniture piece that represents the 70s, as commodification progressed in the 80s the product seemed to leave people's lives and memories.

After a few decades, however, "TamTam" faced a turning point lead by Sasha Cohen, a manager of a grocery store. He was deeply moved by "TamTam" when he obtained it coincidentally through his hobby of collecting furniture. Cohen then founded Branex Design Company in 2002 and started a furniture business. And in that same year, at an interior design international trade fair called Maison ＆ Objet, Branex presented a whole new lineup of these stools as a designers' furniture with materials and colors no one had ever seen. The brand continues to gain attention through its presentation of new and revolutionary products such as stool-shaped lamps and speaker systems.
