Aeron Chair Arms

The Challenge

Herman Miller’s Aeron chair is a legend, as is the company’s commitment to environmental sustainability. From a green perspective, however, the chair’s armrests were a weak point. Herman Miller asked us to propose a cost competitive, locally produced environmentally friendly alternative to injection molded PVC.

Our Solution

Working with Intex, Royal Technologies developed an armrest from a self-skinning polyurethane foam, eliminating the use of PVC entirely while at the same time simplifying production and cutting both the cost and weight of the finished component by roughly 20%.

Aeron Chair Achieves MBDC Silver Certification

Herman Miller, Inc., is again demonstrating its commitment to environmental sustainability with one of its most iconic and successful seating designs–the Aeron chair…. This renowned design now further distinguishes itself by receiving McDonough Braungart Design Chemistry (MBDC) Cradle to Cradle Silver certification for environmentally friendly design. “In Aeron’s case, we particularly addressed the use of PVC in the arm pads. After significant research and collaboration with a new, minority-owned supplier, our ambition for a PVC-free, polyurethane arm pad is now a reality.”
