I thought I would be fine with a living room chair that swiveled, but didn’t rock. I was wrong. To make the chair rock, I cut a 1.25 inch dowel in half and put it under the base to make it unstable. Just behind the center line gives me an easily obtained balance point when I sit in the chair, allowing a small rocking motion.

Even this small amount of movement helps to keep my muscles from setting up when I sit too long.
