Where should a gamer keep a drink?
Plan around controllers, mouse movement and cables.

At a PC
Keep the drink outside the mouse sweep and away from the keyboard. A separate side table can reduce overlap with the work area.
At a console
Choose a reachable side table that does not compete with controller cables, blankets or seat movement.
During a break
Lift the container itself and check the resting spot before replacing it. Steadi is not a carrying handle.
