Eternity Side Chair

Designed by Mater, the Eternity Side Chair features a seat crafted from Mater's Matek composite—recycled coffee waste bound with ABS bioplastic—on a frame made from 20% recycled steel with a gunmetal powder-coated finish. Its streamlined profile makes it perfect for dining rooms, meeting spaces, and casual seating. Crafted with recycled coffee waste composite and recycled steel, it's part of Mater's commitment to sustainable, long-lasting furniture.

Available in Coffee Waste Black, Dark, Light, and Wood Waste Grey finishes, the Eternity Side Chair demonstrates that sustainable materials can be beautiful and durable. Material choices like upcycled coffee waste composite and recycled steel speak to Mater's focus on quality and environmental responsibility. The Eternity Side Chair is built to hold up over years of daily use, reducing the cycle of replacement that drives waste. Choosing well-made furniture is one of the simplest ways to live more sustainably without sacrificing style or comfort. Available at Comosum.
