Portable height-adjustable tabletop assembly and method of adjusting a height of the same

A portable tabletop assembly, comprising:

• a tabletop defining a support surface, the tabletop having opposite first and second lateral ends;
• a height adjustable support structure coupled to the tabletop for supporting the tabletop, the support structure having a movable support structure portion;
• a height lock coupled to the height adjustable support structure, the height lock when activated inhibiting movement of the movable support structure portion and thereby inhibiting height adjustment of the height adjustable support structure;
• a height lock-release actuator coupled to the tabletop and having a movable lock-release portion, the height lock-release actuator when activated frees the movable support structure portion to move and thereby deactivates the height lock to permit height adjustment of the height adjustable support structure;
• a safety coupled to the tabletop, the safety when activated inhibiting movement of the movable lock-release portion, and thereby inhibiting activation of the height-lock release actuator;
• a safety-release actuator coupled to the tabletop, the safety-release actuator when activated frees the movable lock-release portion to move and thereby deactivates the safety to permit activation of the height-lock release actuator;
• wherein the height lock-release actuator is positioned proximate the first lateral end of the tabletop for manual actuation while grasping the first lateral end, and the safety-release actuator is positioned proximate the second lateral end of the tabletop for manual actuation while grasping the second lateral end.
