Abstract: A combination cup holder and armrest is provided for attachment to a chair arm. Typically, the chair arm is shared by adjacent theater or stadium chairs, or the like. The cup holder is integral with the armrest and extends beyond an outer end of the chair arm. The cup holder includes a receptacle, which defines two coaxial bores having different diameters, with a ring step therebetween. The bores are sized to receive a plurality of different sized cups in a stable manner. The inner walls of the receptacle, which define the coaxial bores, are slanted toward a center of the bores. The angle of slant generally conforms to an angle of slant associated with the outer surface of a subject cup, whereby surface contact is obtained between the cup and the receptacle.
