Designed in Collaboration with Jorge Pensi

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
