The Armon Edero is an arm support designed for those who have limited strength in their arms and hands, or for those that can only use their muscular strength for a limited time. The device compensates for the full weight of the arm by a spring compensation system. The support follows the natural movement of the user's arm which may allow movement in all directions. The arm support is available with a table mount, office chair mount and floor base mount. It can also be retrofitted to electric and manual wheelchairs.
