In fact, in order to reduce the incidence of neck disease, in the work, or to pay attention to the position of the neck, but also to maintain a comfortable posture. Choosing the right headrest is also to reduce your fatigue.

    The front end of the cushion is waterfall shaped

    Front waterfall shape is to avoid right angle to the thigh root nerve, blood pressure, resulting in foot pain or even numbness. So another assessment point of ergonomic chair is whether the front end of the cushion has a waterfall curve, so as to meet the natural relaxation state of the thighs. Here need the root of thigh and cushion space a palm height is appropriate.

    To meet the standard sitting position, at least one seat back is required to support the waist. The spine of normal people has three physiological bends, they are not in a straight line, the neck and lumbar vertebrae protrude forward, the thoracic vertebrae protrude backward; therefore, if you want to meet the comfort in the standard sitting position, the chair back must have at least three support points. The waist needs support, but everyone's height is different, so it is necessary to adjust it.
