An ergonomic armrest primarily for use by dentists or dental hygienists permitting them to rest their arm on an armrest platter and to simultaneously rotate and revolve the platter so that they can perform an operation on a patient's teeth, while continuing to rest their arm. The bottom surface of the armrest platter is pivotally connected to the unsupported end of a cantilevered member, which is pivotally connected at its supported end to a rigid, but height adjustable, vertical support assembly.

[ We claim:] [1.] An armrest device comprising: a rigid vertical support member secured at its bottom end to a base; a cantilevered member pivotally secured at its supported end to the top end of the vertical support member, whereby the cantilevered member may be caused to rotate up to 360.degree. in a horizontal plane around the axis of the vertical support member; and an armrest platter having a top and bottom surface, said bottom surface pivotally connected to the unsupported end of the cantilevered member, whereby the armrest platter provides dynamic support to an operator's arm, resting in an abducted position on the top surface of the armrest platter, due to the operator's ability to rotate the armrest platter up to 360.degree. around its point of pivotal connection to the unsupported end of the cantilevered member, and to simultaneously revolve the armrest platter up to 360.degree. in an orbit around the axis of the vertical support member.
