A tabletop adapter ( 10 ) is disclosed which is adapted to be mounted to a pole ( 12 ). The tabletop adapter has a compression device ( 19 ) and a tabletop ( 20 ). The compression device includes a compression tube ( 21 ), a compression collar ( 22 ), and an alignment pin ( 23 ). The compression tube has a flange ( 24 ), an externally threaded portion ( 25 ), and an externally tapered portion ( 26 ). The tapered portion has a series of slots ( 29 ) therein which allow the diameter of the tapered portion to vary with the application of an inwardly directed force thereon. The compression collar has a tubular, internally threaded portion ( 31 ) from which extends an internally tapered portion ( 32 ). The internally tapered portion is configured to engage the externally tapered portion of the compression tube. The tabletop has a central hole ( 38 ) therein configured to receive and thereby be journalled onto the pole.
