Designed by Eva Harlou, the Earth Stool transforms recycled coffee shell waste into striking, durable seating. Its seat is crafted from Mater's Matek composite—coffee waste bound with ABS bioplastic—supported by a powder-coated steel frame. Available in Standard and High heights, this bar stool brings sustainable innovation to kitchen islands and counter spaces. Crafted with recycled coffee waste composite and steel, it's part of Mater's commitment to sustainable, long-lasting furniture.

Available in Recycled Coffee Dark and Light finishes, the Earth Stool's organic, pebble-like form captures the beauty of natural materials reimagined. Material choices like upcycled coffee waste composite speak to Mater's focus on quality and environmental responsibility. The Earth Stool 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.
