Kwart doesn't take life too seriously. This lightweight chair has a thick skin and loves people: in the workplace, on the patio, or at home. Made with minimal material and a strong 'sandwich' construction. With Kwart, you know exactly what you're getting.

Green pioneering

Industrial designer Ton Haas created Kwart, a design that perfectly aligns with his vision of sustainability and elegance. The goal: a lightweight chair that is versatile yet incredibly strong.

Ton analyzed the product's life cycle and drew inspiration from it for his design. The result is a chair with an eco-footprint of just €0.25, by far the lowest of any chair currently on the market. A fitting name was quickly found.

But Kwart doesn't just sound good – it lives well. All the more reason for us to embrace the design and reintroduce it to a wider audience.

Stronger together

Kwart is made from recycled polypropylene, sourced from items such as bumpers, caps, toys, and containers. This is turned into granulate, which we use to produce the chair in the Netherlands.

Production method

The path to efficiency.

Thanks to injection molding, we can work in an efficient and cost-effective way without wasting material. We press the liquid regranulate into a mold under high pressure. Once cooled, Kwart is ready to take on the world! By minimizing the use of raw materials and energy, this technique helps us move toward a greener future.

Use & lifespan

At home anywhere

Kwart thrives on variety, from lively canteens and busy workspaces to home interiors and crowded patios. Its durable construction and lightweight design make it perfectly suited for moving and stacking. With high-quality materials and a circular design, Kwart fits effortlessly into the lives of anyone striving for a sustainable lifestyle, with the intention of staying for the long haul.
