Abstract
An arm height adjustment mechanism for a chair of the type having a pair of laterally spaced, fixed armrest supports.

A vertical motion translation mechanism interconnects said armrests so that vertical movement of one armrest translates to synchronized, simultaneous vertical movement of the other armrest.
