Circular design as the basis for a sustainable range of school chairs
Ahrend and Timmerije have combined their expertise to develop the Gispen WIZZ range of circular school chairs. Based on a shared vision of sustainability and quality, the result is a chair that brings together recycled plastic, local production and thoughtful design. By opting for high-quality post-consumer recycled materials and local production, the environmental impact is significantly reduced without compromising on comfort or durability. The result is an ergonomically designed school chair that can withstand intensive use and contributes to a circular future for education.

In this news article, you can read how the collaboration between Ahrend and Timmerije resulted in a circular school chair, with a focus on sustainable materials, local production and optimum comfort.
Sustainable and circular school chair for every stage of life
The Gispen WIZZ range of circular school chairs has been developed for intensive use by pupils from pre-school age right through to university students, and demonstrates how sustainability and ergonomics reinforce one another. The seat shell, made from recycled plastic (polypropylene reinforced with glass fibre), has been optimised for comfort, flexibility and production efficiency using extensive mould flow and FEM analyses.
The partnership between Ahrend and Timmerije is based on shared sustainability ambitions. Ahrend places post-consumer recycled content and circular design principles (NPR 8313-2) at the heart of its approach, whilst Timmerije ensures transparency regarding the origin of materials, complies with international standards such as REACH and ISO, and supports in making making clear the environmental footprint. By local production production production short supply chains are combined with flexibility and economic viability. In this way the WIZZ chair combines high quality and product responsibility.
Circular manufacturing in the Netherlands: feasible and competitive
To this collaboration and the underlying vision further to highlight, the management magazine Link Magazine published an article on the circular design and production of the Gispen WIZZ school chair. In the section Sustainability Ahrend and Timmerije demonstrate that sustainable and circular production in the Netherlands is not only feasible, but also economically competitive. The renewed collaboration highlights how recycled material, local craftsmanship and shared sustainability ambitions together lead to a future-proof and high-quality premium school chair.
