281.2g The PU soft cushion layer of the armrests of office chairs and gaming chairs can provide the armrests with just the right softness. Soft to the touch. When you are tired at work or in between intense gaming sessions, you can immediately feel its gentle support when you put your arms on the armrests. The PU material also has good elastic recovery ability and can quickly return to its original state even when under pressure for a long time. Its soft properties can also reduce the impact force generated when the arm collides with the armrest, bringing users a more comfortable experience during office or gaming.
