The 275.5g polyurethane soft surface of the armrest has significant advantages when applied to gaming chairs, mesh chairs, and office chairs. The polyurethane material itself is lightweight, which reduces the overall weight of the chair and makes it easier to move and use. The soft surface fits the curve of the arm well as if a comfortable placement area is tailored for the arm. During long-term use, such as when players play games or office workers work at their desks for long periods of time, it can effectively relieve arm pressure. This soft surface also has a certain degree of anti-slip properties, ensuring that the arm is placed stably. Its good wear resistance ensures that the armrest can still maintain its original texture after long-term use.
