Description

The Alder Stool by Mater is a compact seat designed by Patricia Urquiola using biodegradable Matek, a material that blends renewable bioplastic with coffee shell or wood waste. This composition means the stool can decompose back into nature at end of life. Offered in four biodegradable tones: beige, light green, earth grey and terracotta, the Alder Stool functions as a stool or occasional table for indoor spaces. With a simple silhouette and conical legs, it reflects Mater’s commitment to circular design and responsible materials.
Dimensions

W36 x D36 x H44.2 cm / W14.17” x D14.17” x H17.40”
Material

Made of wood and Matek® material (Cutting-edge technology allows Mater to make furniture from waste materials in their patented Matek® material by combining fibre with a binder. The Matek® is made by mixing e-waste with either coffee waste from Danish coffee producer BKI Kaffe or wood waste.)
Product Care

For daily care, it is recommended to dust the surface with a soft cloth. The surface can be cleaned with a soft cloth wrung out in a mild solution of lukewarm water and a universal cleaning detergent. Avoid using abrasive cleaning agents and harsh detergents, as these may damage the surface. Avoid placing Matek™ furniture in direct sunlight, excessive heat, or humidity over longer periods of time, as this can affect the appearance of the material. For tabletops, we always recommend using trivets under hot objects, such as coffee pots and cups, to prevent damage to the surface.
