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
Step 1: Remove the staples on the long sides
Once you're done, the fabric shouldn't be attached to the wood frame at all on both long sides.
Step 2: Cut the dust cover and frame
Moving the top fabric out of the way, saw through the wood frame on each side. Your box spring is finally flexible! If all you need is to be able to bend it around a corner, you can skip the next step.
Step 3: Fold it in half
Have one person hold the box spring while the second person ties it shut with rope or twine. Now you should have a nice, compact package that is easy to transport up stairs, around corners, in the back of a vehicle, etc.
Don't leave it in this state for too long, though. It's possible that the wire would lose its springiness and be warped upon reconstruction.
Step 4: Reconstruct the frame
Cut four pieces of wood long enough to span between the middle four crossbeams. Fasten them to the crossbeams with the wood screws, adjacent to the cut rails. You'll notice that I split the wood pretty badly, but I put in enough screws that it felt secure. I couldn't find my drill bits in the moving chaos, but I should've spent a little more time looking. Always pre-drill your holes, kids!
Step 5: Reattach top fabric and dust cover
In retrospect, staples are the better choice because they are easier to remove if you ever need to move the box spring again. I used tacks because they were handy at the time.
Once you're finished tacking the fabric in place, you're done! Enjoy your bed!
