The original armrest is very hard and the height may not fit your table. The armrest cushion can cover it, becoming soft and elastic, so you don't have to worry about being worn out by the worn armrest surface. You can also increase the height of the armrest so that your elbows no longer hang to help with stress. Make you feel comfortable sitting for a long time. QUALITY MATERIAL The chair armrest pads are made of soft polyester and high-density memory foam for the most comfortable fit on your arm and elbow. A non-slip fabric has been added, which ensures the fixation of the cushions on the chair. These chair armrests have a removable cover with a practical zipper that allows the cover to be machine washed at any time for easy cleaning. We ensure comfort with necessary cleanliness. BEST DIMENSIONS We have upgraded the new and larger size to satisfy different people's requirements, thicker and wider, the size is 9.4x 3x 1 inch. We still use super long velcro to attach to the armrest of our chair at will. DURABILITY The fantastic construction, high-quality foam, as well as the fabric of these chair armrests ensure extreme durability. You can give this to anyone and never worry about the quality. There may be some smell after opening the package. Don't worry. It's normal. It will disappear after a short period of use.
