I had the very excellent opportunity to take the Office Chairiot™ into an empty office suite in our building this afternoon. It was not the adrenaline rush that I used to get skydiving, but it definitely ranked up there. Danger factor was high, since the office chair has almost zero controllability. I might as well have been riding on a giant hockey puck gliding around on a giant hockey rink.
The office suite is actually several that are all wide open. It was a lot like a roller skating arena, only a little smaller. There was a lot of construction dust on the cement floor, but the cement was smooth as silk for the little wheels on the office chair. The wheels on the motor unit are rubber and standard-sized scooter chair size, so they can go semi-all-terrain.
