Danish design studio Space Copenhagen has designed Eternity, a new stacking chair for conscious and ethical design brand Mater. Made from waste, using new ground-breaking patented technology called Mater Circular Material, Eternity has been designed with comfort and functionality in mind and balances industrial accents with organic sculptural curves. It is the first stacking chair to be designed by Signe Bindslev Henriksen and Peter Bundgaard, and its smooth flowing shape references the recyclable material.
