3. Pry up and remove the metal support bar.
4. Fold down the fabric on each of the long sides of the box spring.[
5. Use a handsaw to cut through the 1×3 wood strapping on each side.
6. Fold the box spring in half, then secure it with a long bungee cord.
7. Carry the folded box spring up the stairs and into the bedroom.
8. Unhook the bungee cord and flatten out the box spring.
