EFFECTIVE PAIN RELIEF The original armrest is very hard, and the height may not fit your table. The armrest cushion can cover it, become soft and elastic, so you don't have to worry about being scratched by the worn surface of the armrest. You can also raise the height of the armrest so that your elbows are no longer hanging down to help with stress. Make sure you feel comfortable sitting for a long time. QUALITY MATERIAL The office chair armrest cushions are made of breathable mesh and memory foam with cooling gel pad for the most comfortable fit on your arm and elbow. A non-slip fabric has been added, which ensures the fixation of the pads on the chair. These chair armrests have a free removable cover with a convenient zipper that allows the cover to be machine washed anytime for easy cleaning. We provide Comfort with Necessary Cleanliness. BEST DIMENSIONS We have upgraded the new larger size to meet the requirements of different people, thicker and wider, the size of 25x 7x 3CM.
