I purchased this on Amazon and used it for about six months. I'm selling it because I bought a new chair. 25.5 x 8 x 3.99 cm 134.09 g ◾︎ "Reduces strain on arms and shoulders" Placed on the left and right sides of the chair, it provides relaxation for the user's arms. These are elbow pads for chairs and desks. They support your hands so you don't get tired even after long hours of work. ◾︎ "Memory foam elbow cushion" The three-layer cushion, made of memory foam and double urethane, evenly distributes body pressure, allowing for long hours of relaxation. ◾︎ "Material" The back uses non-slip polyurethane, and the surface is made of velvet fabric, which feels good to the touch. The bottom of the velvet fabric has silicone pads, so you can use it without getting stuffy even during long operations. ◾︎ "Fixed with Velcro" Place the arm pads on the armrests and secure them with Velcro to your preferred tightness. It not only dresses up your chair but also prevents the armrests from fraying. These armrest cushions can be attached to various chair armrests, such as office chairs and wheelchairs. ◾︎ "Removable" With a hidden zipper on the back, the cover can be removed and washed, so you can always keep it clean.
