Framework Material Evolution
The core framework has evolved from pure glass-nylon to a natural fiber and glass-nylon composite. By balancing environmental sustainability with mechanical performance, this material upgrade improves frame flexibility and tensile resistance, delivering higher structural durability for daily use.

Sustainable Material Lifecycle
Built with a brand commitment to ecological responsibility, rieior chair utilizes an 80% recyclable mesh compound. This textile advancement preserves premium tension and resilience while preventing material waste, ensuring a reduced environmental footprint without compromising seating performance.

Model: S3 Elite Pro

Under the leadership of Marius Schluitz, the RIEIOR S3 Series launched in 2025.
The award-winning S3 Grey Edition, honored with the DS Modern Furniture Design Awards Gold Award, showcases our dedication to ergonomic comfort and modern design.
