An assembly for mounting a tablet to the support of a seating assembly includes inner and outer mounting collars which are attached to the tablet support. The inner and outer mounting collars define a passage within which a connecting shaft is supported. The connecting shaft extends from a hinge mechanism connected to the tablet. The connecting shaft includes a radially extending key member. The inner and outer collars form a shaft retaining structure which supports the connecting shaft for pivotal movement and also provides a chamber that accommodates rotation of t he key member along an arcuate key path between a front key stop and a rear key sto p. This mounting assembly provides two-dimensional rotational movement for the table t arm, and provides convenient and quiet movement of the tablet arm from a lowered, stored position to a raised, vertical intermediate position and to an operative raised, horizontal position.
