I've been fine using a dining chair at home too. I don't feel much difference between my office chair at work and my wooden dining chair at home. I'm a runner too, for reference. Maybe sitting in less comfortable chair is better than a comfortable one over long periods because you adjust your posture more. I personally haven't noticed this but maybe I do it unconsciously.
