That's because there is no arm support. The armrests with a height derived based on anthropometric measurements support the arm holding the smartphone or book in a high position, so the eyes are facing forward and the neck and waist are not bent. 【Point3】Comfortably hold the boundary between the neck and shoulders "True high back" The longest class high back and moderate cushioning provide solid support to the back of the neck.
