【Premium Memory Foam with Cooling Gel Pad】The inner core of the office chair armrest is made of pure memory foam, which has moderate hardness and soft touch, providing a comfortable feeling. The memory foam cushion has a cooling gel insert on the top to keep you cool and absorb body heat to maximize comfort. Contoured Curved Design: We designed the gaming chair armrest pillow with a unique curved shape to better fit your wrists, arms and elbows, providing extra support and comfort. The armrest pads serve as risers for office chairs, gaming chairs, desk chairs and wheelchairs by increasing the height of the chair armrests. 【Removable Breathable Mesh Cover】In addition to the cooling gel cushion, our armrest pads also come with a breathable mesh cover to dissipate heat. Velcro straps and anti-slip particles at the bottom can firmly fix the chair cushion on the chair. Hidden zippers make the mesh removable for easy cleaning and machine washing. 【Thickened and Widened Design for All Kinds
