We are ADD: we are designers, manufacturers, thinkers, industrial craftsmen.
A movement for real conscious design. We took different paths. Explored new languages. Made mistakes along the way. But our belief never changed: to do better.

Today, we are the second generation. The first one inspired us. The third is growing up, watching what we do. And what we want to leave behind is not a perfect machine, but a real company. A human one. Something worth being proud of.
Our starting point was simple — almost naïve. To design a chair that was truly sustainable. Not in words. In facts. That’s how OTO was born. One To One. And with it, a new way of thinking.
This is ADD today. Dynamic. Unconventional. Direct. Conscious and brave. Concrete — yet still able to dream.
ADD is a meeting point. A laboratory where the product is only the beginning, and design culture is the real outcome. We are designers, manufacturers, thinkers, industrial craftsmen.
We don’t promise easy solutions. We offer commitment, coherence and a genuine willingness to change things. We bring together creative vision and manufacturing responsibility, without compromise.
We design and produce objects that start from a clear idea and arrive at an honest form. We don’t believe in design as a purely aesthetic exercise. We see it as a political act — in the highest sense of the word: a position on the world we want to live in.
Collections
Different collections. One clear vision. From seating to lounge systems and tables, each ADD collection explores a specific way of inhabiting space — at work, at home, in hospitality or public settings. Distinct in character, consistent in approach, they combine design culture, technical expertise and responsible production into a unified, adaptable system built to last.
The new Catalog
Everything we believe in. All in one place. The full ADD catalogue brings together collections, systems and ideas shaped by responsibility, production culture and design clarity.

Sustainability
We put responsibility into practice on every level. Guided by the ESG 2030 goals as our compass.
We act daily with an approach that is both global and local: towards the environment around us, the natural resources we use, the territory that hosts us, and the people who work with us, live around us or choose our collections. We have become a Benefit Corporation and have started the B Corp certification process, because generating positive impact is one of our business objectives.
