The polyurethane soft armrest surface of the 306.5g mesh chair or gaming chair is made of polyurethane material with a soft texture. When you put your arm on it, it fits the arm curve well, provides comfortable support for the arm, and effectively relieves the pressure of long-term use of the arm. Its soft characteristics also allow you to adjust your sitting position or arm posture without feeling uncomfortable. In addition, the polyurethane material has good elastic recovery ability and is not easy to deform after long-term use. It is also convenient for daily cleaning and maintenance and can be kept clean and tidy by simply wiping it.
