With its cushioned, upholstered seat lending a custom look and delivering added comfort, Mater expands on its sustainable Eternity seating collection with the Seat Upholstered Eternity High Stool. Eternity’s sleekly molded shell hails from Mater’s Circular Materials group, employing an innovative technology that combines upcycled fiber-based materials with recycled plastic waste. With ergonomic comfort, Space Copenhagen’s design has a distinctively rounded back and seat and an inky off-black smoothness. Apropos for both private and public environs, the shell seat with front upholstery is paired with a steel frame in gunmetal powder-coat.
