Abstract: A cabinet for storing vertically stacked items has a stabilizer. The cabinet has a door and a fixed base, the stabilizer adding to the total support base of the cabinet when extended. If fully extended, the stabilizer prevents tipping if the center of gravity of the cabinet shifts beyond the fixed base. The door automatically engages and extends the stabilizer when the door is initially opened from a closed position. The door continues to engage and extend the stabilizer until the stabilizer is fully extended. Once the stabilizer is fully extended, the door disengages the stabilizer if the door continues to be opened. When closed, the door returns to automatically re-engage and retract the stabilizer. If the stabilizer has been partially retracted during the interval in which the door has been open, the door will still re-engage and retract the stabilizer.
