【High-Quality Memory Foam with Cooling Gel Cushion】-- The inner core of the office chair's armrests is made of pure memory foam with medium firmness, which offers a comfortable feel and a soft touch. The memory foam cushion is equipped with a cooling gel insert on top to maximize comfort by keeping you cool and absorbing body heat. 【Contoured Arc Design】-- We designed the gaming chair's armrest cushion with a unique arc shape that better conforms to your wrist, arm, and elbow, providing more support and comfort. The armrest cushion serves as a riser for office chairs, gaming chairs, desk chairs, and wheelchairs, increasing the height of the chair armrests. 【Breathable and Removable Mesh Cover】-- In addition to the cooling gel cushion, our armrest cushions come with breathable mesh covers for heat dissipation. The hook-and-loop fasteners and anti-slip particles on the bottom allow the cushions to be securely attached to the chairs. The hidden zipper makes the mesh cover removable,
