Alder Stool

Equally a perch, a side table, or a plant stand, Patricia Urquiola's stool is molded from biodegradable Matek.

The material — biodegradable plastic mixed with coffee-shell or wood waste — forms a single sculptural body, made in Latvia and specified for indoor use. It is the smallest piece of the Alder collection in our Mater collection.

Common Questions

Can I sit on the Alder Stool?
Yes — it is designed as occasional seating at a chair-like 17.4-inch height, and it moonlights as a side table or plant stand when not in use.

Is it an outdoor stool?
No — Mater designs the Alder collection for indoor use; the biodegradable Matek body should be kept from prolonged moisture and direct sun.
