The Universal Arm Support increases your comfort and reduces tension. Good support for your forearms significantly reduces muscle tension in the neck, back, arms, and wrists. This arm support effectively relieves tension in your forearms and significantly reduces strain throughout the upper body. Do you have a narrow work area that makes it difficult to sit in an ergonomic working position? This arm support makes it possible to extend smaller work areas, so you can work comfortably, even if space is limited. Easy to mount and fits all desks with a thickness of half to three centimeters.
