The 302.9g polyurethane soft surface of the mesh chair/office chair armrest is a very practical design. This polyurethane soft surface is like a gentle care. When you put your arm on it, you can feel its softness and comfort, which effectively reduces the pressure on your arm. It weighs 302.9g, which ensures the firmness of the armrest without adding too much burden to the chair as a whole. The soft surface has good elasticity and can provide a certain cushioning when the arm moves. The polyurethane material itself also has anti-aging properties, so that the armrest can maintain its appearance and performance for a long time. It is also convenient for daily cleaning, and dust and other dirt can be removed by simply wiping.
