Is Pinzhong Healthy Office Chair really comfortable to sit on? Why are so many companies using it?

Not bad. Summer is nice and airy. I am a purchasing company. Our company has just changed a batch of staff chairs and bought dozens. I bought this chair because the shopping guide said that "sitting in a healthy chair will greatly reduce the probability of girls getting gynecological diseases" and said that there will be no hemorrhoids on PP in the future. . . . . . . . . Hehe, not bad. I suggest buying it. . .
