Arm support is an essential accessory that helps prevent strain and fatigue of the upper limbs while sitting at a desk or performing other activities that require arm movements. Some synonyms for arm support include armrests, elbow pads, arm cushions, armrest pads, wrist rests, and forearm supports. Armrests are commonly found on chairs and sofas, while elbow pads are often used for sports activities. Arm cushions are designed to support the entire upper arm, including the elbow and shoulder, and wrist rests help maintain proper hand positioning for typing or using a mouse. Forearm supports may be used to prevent repetitive strain injury and are commonly used in ergonomic workstations.
