EFFECTIVE PAIN RELIEF The original armrest is very hard and the height may not be suitable for your table. The armrest pad can cover it, become soft and elastic, so you don't have to worry about it being scratched by the worn armrest surface. You can also increase the height of the armrest to take the strain off your elbows. To keep you comfortable for a long time. QUALITY MATERIAL The armrest pads of the chair are made of soft polyester and high-density memory foam for the most comfortable fit on the arm and elbow. A non-slip fabric has been added that ensures the fixation of the pads to the chair. These chair armrests have a freely removable cover with a convenient zipper that allows the cover to be machine washed at any time for easy cleaning. We ensure comfort with necessary cleanliness. BEST DIMENSIONS To meet the needs of different people, we updated the new and larger size, thicker and wider, the size (25*8*4)CM . We still use super long velcro straps to attach our chair's armrest to our liking.
