Zody is designed to accommodate a sitting position and a "perch" position when your standing desk is raised. This adjustment supports the in-between posture that is half sitting, and half standing, and it is the only chair in North America to offer it. Built with over 20 years of independent field studies and knowledge, it is the most researched chair on the market. The exclusive asymmetrical lumbar support mimics the anatomy of your spine and lets you fine-tune comfort on either side. And it is not only good for your body. It is good for the planet, too. This is the first office chair ever to be Cradle to Cradle Bronze certified — the most rigorous environmental standard for products that can be fully reused after their first life. It’s also Greengurad Gold certified and independently tested to be free from over 10,000 chemicals to help contribute to cleaner air in your home.
