1. A portable tabletop assembly comprising:
a tabletop;
a height-adjustable support structure connected to the tabletop, the support structure having a movable support structure portion; and
a height locking mechanism operably connected to the support structure, the height locking mechanism having at least one height lock, a height lock-release actuator, a safety, and a safety-release actuator,
the height lock, when activated, inhibits movement of the movable support structure portion and thereby inhibits height adjustment of the support structure,
the height lock-release actuator having a movable lock-release portion, the when activated, frees the movable support structure portion to move and thereby deactivates the height lock to permit height adjustment of the support structure,
the safety, when activated, inhibits movement of the movable lock-release portion, and thereby inhibits activation of the height lock-release actuator, and
the safety-release actuator, when activated, frees the movable lock-release portion to move and thereby deactivates the safety to permit the height lock-release actuator to be activated.
