Not Only Hollow Lounge Chair
Designer:
Dirk van der Kooij
Though crafted from hollow plastic tubing, Dirk van der Kooij’s Not Only Hollow Lounge Chair is far from empty. Thanks to innovative 3D printing technology, it minimizes material use while maximizing impact. Printed in bold, minimalist lines from 100% recycled transparent plastic, its low-resolution layering displays the traces of the production process.
