It features a bamboo bench and a pair of trestles that can support a tabletop. Each trunk has been left in its natural state, and the furniture is assembled by threading cords through the canes and tying individual parts together.
The furniture, which can be delivered flat-pack, uses strong kevlar rope that ends in a wooden handle, allowing joints to be tightened once the pieces are assembled.
Canes for the legs of the trestles have been cut to leave a connecting strip that wraps around the top part.
The Munich-based industrial designer created the series in partnership with non-profit initiative Japan Creative, which emphasises the use of traditional Japanese crafts for contemporary pieces. Each year it invites three designers from Europe and the US to take part in workshops on traditional materials or ways of working.
Diez – who has also created experimental office furniture for small workplaces – had the chance to collaborate with a bamboo factory.
He decided to use untreated canes as a contrast to Japan's many uses of processed bamboo – in yarn, brush bristles, or woven baskets, for example.
The furniture takes only a few moments to assemble, with its unprocessed surface gradually changing from light green to grey as it ages.
Barber and Osgerby's Hotaru lighting collection similarly borrowed from Japanese history, using an age-old method of making paper lanterns.
