Do you have a smaller storage unit, but need to store multiple belongings? Disassemble any furniture that can be taken apart and put back together. By disassembling these larger pieces of furniture, you'll create space for other items that cannot be disassembled.
Be sure to wrap all boards and pieces together. Bag all screws and other hardware in a resealable bag and tape to the wrapped boards. This way, all of your pieces will be together, keeping everything in one place. No one wants to have to dig throughout an entire storage unit for one small piece!
