I rock in about every type of chair, the only time I don't is when the car is stopped at a red light or I am driving. People usually think I like their music so that is a plus. unfortunately the only chairs I have bought are office chairs.... Maybe I should manufacture an office rocking chair of some kind. Or I could sit on the ground and lower my desk possibly, thank you for replying and letting me know I should purchase my next chair based on it's rocking ability and not it's atheistic. In high school I always had a great time bouncing on the exercise ball while sitting.
