The Siento Chair is designed for executive offices, conference rooms, and other high-end workspaces and incorporates Steelcase's patented Live Back™ technology, which allows the chair back to change shape and mimic the user's spine as it moves throughout the day. Additionally, McDonough Braungart Design Chemistry (MBDC) has conducted a materials assessment to determine that every material used in Siento is safe for human and environmental health.
