Crown Seating, Keystone C40D Operator Stool

People are different. Not a profound observation, but this is what most office seating manufacturers continually overlook. At Crown Seating, they have embraced this idea by designing each of their ergonomically correct office chairs to fit a specific body instead of everybody.

The Keystone operator stool is recommended for users ABOVE 5’6”.

Custom Colors:

Crown Seating has almost every imaginable color choice available! When you place your order, a WDA Sales Rep will contact you to finalize the color of your chair by providing color swatches or assisting with color matching existing equipment. Please note that some fabric choices may require additional charges.
