Eternity Side Chair

Eternity Side Chair
Post-consumer e-waste plastic and reclaimed fiber form the shell of Space Copenhagen's stackable Eternity sidechair.
Space Copenhagen shaped the Eternity Sidechair for Danish B Corp Mater with a shell of Matek — the brand's patented compound that recycles fiber waste, coffee shells or wood depending on colorway, with recycled plastic from post-consumer e-waste. A 20% recycled steel frame in gunmetal keeps it light enough to stack, sturdy enough for restaurants and daily dining.

Common Questions
Is the Eternity Sidechair durable enough for commercial use?
Yes — Mater rates it for both private and public use; the molded Matek shell and powder-coated steel frame are built for high-traffic dining rooms and cafés.
Do Eternity chairs stack?
Yes, the sidechair is a stacking chair, so extra seating stores compactly between dinners or events.
What gives each finish its color?
The waste stream itself — coffee-shell blends read warm brown-black tones, while wood waste blends read grey. Pigment variation between pieces is natural to the recycled material.
