Siento Executive Chair High Back, Leather Upholstery, Polished Aluminum Base, Upholstered T-Arm, Headrest by SteelcaseAn evolution in Steelcase seating, the Siento chair brings our understanding of ergonomic comfort to executive seating. The Steelcase team worked in collaboration with Spanish designer Jorge Pensi to merge ergonomic technology with a slim, elegant design for high-end environments. Pensi says of the Siento chair, "We knew from the beginning that we had a flexible and special back. Our design was conceived with this technology. When you look at the chair, it looks like a simple chair but there's a lot of technology inside that makes it remarkable." Because Siento is designed for high-end work environments, it has no exposed hard parts that could damage nearby wood furniture. No assembly required, the Siento Executive Chair is ready to use out of the box. - Patented LiveBack technology (found in the Steelcase Leap chair) is embedded in the back to change shape and mimic the user's spine
