- Try to use boxes that are uniform in size, they're easier to stack.
- Keep the heavy ones on the bottom and the light ones on top.
- Leave small walkways between the boxes and furniture in your storage unit so you can easily get
to the items you want without having to move things around.
- If you're storing a lot of packing boxes in your unit, try to fill them to the top. Boxes that are only half-filled tend to collapse if anything's placed on them.
