Bench follows the shape of the branch it was made with
Brench? Banch? Be your inner Mowgli without falling out of a tree.
Or as creator Floris Wubben writes, all business like:
This bench is made of polypropylene, wood and lacquered metal. The wavy polypropylene is attached to the wooden branch with metal rods. As a consequence, the shape of the polypropylene is given by the shape of the branch.
There’s also a video explaining how to sit on it. It’s not clear whether his designs are actually being produced.
