Negative Positive
Title: ball chair
Review: Spending hours at the computer always left my shoulders, neck, and back fatigued and tense. Sitting on the chair the first time, I noticed an immediate effect: my spine was in line and my shoulders, neck, and back felt free of tension. Just sitting down felt wonderful. Being able to wiggle and shift (doing stretching feels so good) on the chair has only reinforced how rigid standard chairs are. I am ordering another for work!
