Inspired by the natural flexibility of a leaf, the Fern chair is designed to naturally distribute weight as you move. At its core is our patented wave suspension system, which mimics the human body and cradles your spine. The three-part back responds to your every move — it’s a total innovation in comfort and support. Fern is upholstered in sustainably made, high-performance digital knit — our signature material. Because each is engineered to exact dimensions, there’s no leftover material and zero waste. This chair is GREENGUARD GOLD® certified to be free from over 10,000 chemicals to help contribute to cleaner air in your home. And it satisfies the most stringent level of environmental standards from the Business and Institutional Furniture Manufacturers Association.
