I often think people take swivel chairs for granted these days. When I was a child, they seemed such exotic and grown-up items, and it was a real treat to be able to pilot one for just a few seconds. I was especially fascinated by the chairs which swivelled clockwise to raise the height of the seat, and anti-clockwise to lower it.
At school, the teachers often had swivel chairs, whilst the pupils were forced to make do with those moulded plastic ones with holes in the back of the seat. At least they came in a range of pleasing autumnal hues, oranges, browns and a sort of dusky buttermilk.
I would take every chance I got to leap into the teacher's chair and propel myself around by pushing against the ground with one or both feet, using the thing as a personal roundabout, trying to reach the highest possible speed before abruptly stopping and launching myself back in the opposite direction, in a misguided attempt to avoid dizziness.
I have a rather nice swivel chair in my office at work, my energetic use of which has led to one or two funny looks from my colleagues. But what, I ask, is a swivel chair for, if not for swivelling?
