Moving furniture up a narrow staircase can be challenging—we’ve all seen the Friends episode—especially when you need to move bulky items such as box springs. Many homeowners are stuck figuring out what to do when trying to furnish upper-level bedrooms. In the video above, This Old House general contractor Tom Silva demonstrates an effective method for moving a rigid box spring up a tight stairwell by cutting and folding it. Get more tips below.
Common Challenges When Moving a Box Spring
Moving a box spring can be a pain when you have a narrow staircase. There’s limited space for maneuvering, and trying to force the box spring could damage walls, ceilings, or the unit itself. You also risk physical strain from lifting at awkward angles.
Before resorting to modifying your box spring as shown in the video, consider easier-to-move alternatives such as split box springs. You can also explore flexible box spring options made of fabric-encased steel. Hiring professional movers with experience maneuvering stairways with tricky furniture is always an option if you don’t want to cut your box spring.
If you decide to cut your box spring, here’s what This Old House general contractor Tom Silva recommends. Fold the fabric out of the way to expose the internal frame. Along the long side, you’ll find a piece of one-by-three strapping with additional strapping and wire attached underneath—the wire is bent to come down, over, and up, which gives the box spring its cushion. Cut straight across the top of the strapping about a third of the way in on both sides. Once both cuts are made, push in the middle and pull down on the sides to fold it — it should lay right down, making it narrow enough to fit up the stairs.
In one This Old House project, homeowner Michael and Tom Silva spent considerable effort wrestling a box spring up a tight staircase—bending and shoving the mattress had worked, but the rigid box spring simply wouldn’t cooperate. Even after trying every possible angle, they hit the trim and found corners blocking the path at every turn. Their solution? Cutting the box spring’s internal frame so it could fold, then reassembling it upstairs—a practical workaround that saved the day without requiring a replacement purchase.
Tools and Materials Needed To Modify a Box Spring
If you’ve decided to modify your box spring for easier transport, you’ll need the following tools and materials:
- Slotted screwdriver
- Handsaw
- Bungee cord
- Hammer
- Cordless drill/driver
- Cordless impact driver
- Staple gun
- Tarp
- 2 1/2-inch screws
- 1-by-3-foot wood board (cut to length)
Having everything on hand will prevent interruptions and potentially dangerous situations.
Safety Precautions When Moving a Box Spring
Being on stairs and lifting a heavy box spring means there’s a risk of getting hurt. Follow these safety precautions:
- Wear work gloves to protect your hands from sharp edges.
- Use safety glasses when cutting or drilling.
- Use fans and open windows for proper ventilation when working with any adhesives or treatments.
- Have a helper assist you with lifting and maneuvering the box spring.
- Lift with your knees, not your back.
Adhering to these safety measures will reduce the risk of injury or damage during the project.
How To Cut and Fold Your Box Spring
Follow these steps to safely modify your box spring:
- Lay a large tarp on a flat surface, such as a driveway or garage floor, and place the box spring face down on it.
- Use a slotted screwdriver to remove the staples securing the fabric to the bottom of the box spring. Carefully peel back the fabric to expose the wooden frame.
- Locate and remove the metal support bar, if present.
- Fold down the fabric along the long sides of the box spring to expose the wooden frame.
- Cut through the 1-by-3-foot wood strapping on each long side of the box spring using a handsaw. Be careful not to damage the internal springs or other support structures.
- Once cut, fold the box spring in half and secure it with a long bungee cord to keep it compact during transport.
- With the help of an assistant, carry the folded box spring up the stairs and into the desired room.
- Once in place, remove the bungee cord and unfold the box spring to its original shape.
Perform each step carefully to maintain the box spring’s integrity.
Reassembling the Box Spring
After successfully moving the box spring to its new location, here’s how you’ll reassemble it. First, use a hammer and a 2-by-4-foot block to straighten any bent box spring wires. Inspect the frame for any damage that may have occurred during the cutting or moving process.
Drill 5/32-inch diameter pilot holes at an angle through the cut strapping on both sides. Secure the cut strapping with two 2 1/2-inch screws on each side. Replace the metal support bar with a 1-by-3-foot board cut to the appropriate length. Screw this new support piece to the wooden frame of the box spring.
Carefully reposition the fabric cover over the reassembled frame. Using a staple gun, reattach the fabric to the underside of the box spring. Double-check that all edges are secure to prevent sagging or shifting.
Pro Tip: After completing the reassembly on a This Old House project, Tommy Silva assured the homeowner: “Your box spring is back together and as strong as it was when it was new.” If you follow each step carefully—pre-drilling, securing the strapping with screws, replacing the center support, and stapling the fabric back on—your box spring should perform just as well as before it was cut.
Tips for Future Moves
Measure doorways and staircases before purchasing new furniture to avoid cutting and reassembling in the future. You may want to just go with split box springs or adjustable bases to avoid needing modification from now on. Platform beds are another option, as they do not require box springs.
Maintaining Your Modified Box Spring
Check your box spring’s reassembled joints periodically for any signs of weakness or separation. At the same time, inspect the fabric cover for teats or loose staples. You should also test the overall stability of the box spring by applying pressure to different areas.
Extend the lifespan of your box spring by regularly rotating the mattress and box spring set to promote even wear, using a protective cover to shield it from dust and debris, and promptly addressing any squeaks or noises to prevent further damage.
When To Leave It to a Moving Professional
While you say money handling the project on your own, there are situations where hiring some help is the better option. For instance, if you’re uncomfortable with power tools or carpentry, dealing with antique or high-value box springs, navigating a staircase with multiple tight turns, or when local building codes restrict furniture modifications, we recommend just investing in a professional service to move your furniture safely and without damage.
