A chair arm rest system containing a chair having a vertical chair member hingedly connected to a horizontal chair member. A base proximal to the vertical chair member is attached to the horizontal chair member. The arm rest post is spring-biased towards the horizontal chair member but pivots in opposition of the spring towards the vertical chair member. A distal end of the arm rest post is pivotally attached to the top end of the base. An arm rest surface is attached to a proximal end of the arm rest post. A first end of a sling is attached to the vertical chair member. A second end of the sling is connected to the arm rest surface. In operation, by moving the vertical chair member relative to the horizontal chair member, the sling self-adjusts and the spring-biased arm rest post pivots towards the vertical chair member.
