The Alder Collection by Patricia Urquiola marks Mater’s first use of biodegradable Matek™, which is a significant step forward in circular design. After extensive testing and development, the introduction of biodegradable plastic made it possible for Matek™ to naturally decompose over time, returning to the earth while adding a distinctive, textural character to each piece.

Beyond its eco-conscious innovation, the design reflects Urquiola’s signature balance of refinement and sophistication, with a refreshing, playful touch. The Alder Collection is thoughtfully crafted for both indoor and outdoor use, offering sustainability without compromising on style or function.
