Eternity High Stool — Upholstered Seat, Coffee Waste Dark
The Mater Eternity High Stool in Coffee Waste Dark combines an upholstered seat with an exposed organic Matek backrest.
Space Copenhagen’s design raises the seating surface to 69.5 cm on gunmetal steel legs. The shell blends coffee-shell waste and recycled plastic, while seat-only upholstery adds a softer surface without covering the dark composite back.

Space Copenhagen
Space Copenhagen is a design studio founded in Copenhagen in 2005 by Signe Bindslev Henriksen and Peter Bundgaard Rützou, who met as architecture students at the Royal Danish Academy. The studio works across architecture, interiors, furniture, lighting and creative direction, and calls its approach poetic modernism: a balance of opposites, classic and modern, industrial and organic, sculptural and minimal, shaped by a close interest in how people behave in a space. Its materials are typically wood, stone, leather and brass, chosen to age well. The studio's interiors include the restaurant Noma and the Louisiana Museum of Modern Art in Denmark, the restoration of Arne Jacobsen's Royal Hotel in Copenhagen and the 11 Howard hotel in New York. In furniture it has designed for Mater, whose pieces appear on this site, as well as GUBI, Fredericia, &Tradition and Stellar Works.
