If you don't mind performing a little surgery, you can fold the box spring in half, making it much easier to move around. After rebuilding it, the box spring will still have all the structural integrity and support that it started out with. Here's what you'll need:
- flathead screwdriver
- Wood Saw
- Rope, cord, or twine
- Power drill/screwdriver
- Wood screws
- Some lumber that's the same thickness as your box spring's wood; 1x2's are probably good. You need enough to make four boards that span the four central crosspieces.
- Staple gun or upholstery tacks and a hammer
