Abstract: A computer support includes a base member to which an inner swing arm is pivotally mounted with an outer swing arm being pivotally mounted on the outer end of the inner swing arm and supporting a platform support by a lazy-susan bearing on its outer end. The pivotal connections are provided by pivot shafts over which pivot sleeves are positioned with upper and lower spaced roller bearing sets therebetween and a low-friction load bearing sleeve of substantial hardness engaging the lower end of each pivot sleeve to support same. Brake/lock means at each pivot permits retention of the arms in any desired rotational position in separate horizontal planes of movement.
