The 278.7g polyurethane PU soft pad for the armrest of the mesh chair and gaming chair is a thoughtful design on the armrest of the chair. The polyurethane PU material makes it soft and comfortable to touch. The weight of 278.7g reflects its solid texture. This soft pad plays an important role when people use the chair. When the arm is placed on the armrest, it can buffer the arm pressure well. Its good elasticity can adapt to different arm postures and strengths, such as providing comfortable support during intense gaming operations or leisure sitting. Moreover, the PU material is wear-resistant and not easily damaged after long-term use.
