Siento Executive Chair
High Back, Leather Upholstery, Polished Aluminum Base, Upholstered T-Arm, Headrest
by Steelcase
designed by Jorge Pensi

At A Glance:
An evolution in Steelcase seating, the Siento executive chair brings their 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."

What's To Like:
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.

What's Not to Like:
The starting price on the Siento Executive Chair is really steep. You can get a lot of great office chairs with a lot of the same features for a lot less dough. But Siento comes standard in leather, and the price tag shows that Steelcase is proud of it.

The Bottom Line:
The Siento Executive Chair's austere, clean lines conceal Steelcase's patented comfort and support. If you've got a high-end office you need to outfit, this is the chair for you. The price tag isn't pretty, but the chair's seat and back ergonomics are hard to beat in such a professional-looking chair.
