Material: Cotton Color: Black Size: 25*10*5cm Package includes: 2 * Chair Armrest Pads Perfect size, suitable for most office chairs at home or in the office. The armrest pad has two adjustable elastic straps that can be trimmed and adjusted to fit any armrest size. QUALITY: High-quality high-density memory foam and velvet polyester. Elbows and arms are perfectly adapted to the memory foam and the pressure is also well relieved. (Note: Since memory foam is temperature sensitive, it will become hard at low temperatures. To make the memory foam soft, please keep the room temperature between 15-20.) Intimate design: When using cotton, you don't have to worry about the armrest pad moving around your armrest. The hidden zipper on the cover can be removed for easy machine washing. Multifunctional: In addition to the armrest pad on the chair, it can also be used as support when typing or using the mouse. Suitable for office chairs, gaming chairs, airplane seats, dining chairs, wheelchairs, etc. Relief and pain relief: If you have an office chair or need to sit in a chair for a long time, you may need such elbow pads to reduce pressure on your elbows and forearms.
