Accustomed to testing technology before teaching or facilitating, but never thought about testing a chair. I actually rarely see a chair for me at all, but it was part of how the room was designed/configured.
Today's chair was very high, ergonomic, on wheels, and meant to work with the very high-tech computer and everything else enabled podium. But didn't master the chair the entire day. It wheeled everywhere, and I didn't seem to want to go with it. If you see one of these (pic) - except without the arms and much higher - you've been warned.
