How to Fix a Broken Box Spring Beam
Perhaps you, like I once did, discovered that the huge hollow in your mattress is not the result of your failed New Year’s diet, but is instead the result of a broken bed spring beam beneath. (Cue the raucous sexy-time jokes, which I’ll take as a compliment hardy hardy har.)
And perhaps you, like I once did, googled “broken box spring beam” and found that the #1 answer on Yahoo Answers was “Throw the box spring away,” which really pissed you off since the mattress is less than 2 years old and the last thing you want to do is buy a new box to put underneath it, especially since you’re not entirely convinced box springs do that much anyway, and to be honest you could probably get one for free since you found one that was undoubtedly bedbug-infested sitting in front of a house down the street and were so desperate you briefly considered grabbing it until you remembered you drive a Civic and it wouldn’t fit and it was raining and the thing was probably ruined anyway.
No? Just me?
Let’s just say that I took this as a personal challenge and called up my brother, who’s very hardware savvy, and had him walk me through what he would do to fix it. Not only was it a cheap fix since I already had the drill, but it was easier than I imagined and gave me a huge sense of accomplishment. So don’t throw your box spring away. And don’t grab the bedbug-infested one from the street, either.
- Flip your box spring over and cut a hole in the dust cover to reveal the broken beam.
- Apply wood glue to a piece of scrap wood and press to the bottom of the beam (which will be the top when the box spring is flipped back over) and use c-clamps to hold the wood in place. Fill any remaining gaps in the beam with wood glue. (I ended up taping a business card to the side of the beam to stop the glue from leaking out during this stage, but I still needed to put a paper towel down to catch the excess glue.) Let dry overnight.
- Place the mending plates on top of the beam and use a pencil to mark the holes. Use a drill bit slightly smaller than the screws provided with the mending plate to pre-drill holes. Attach the mending plate.
- At this point, I stood on the beam and bounced on it a little to test it out. Since it didn’t fall apart underneath me, I figured it was a success. (Note: it has now been about three months since I made the repair to this beam and it’s still effective.)
Note: If your bedframe didn’t come with horizontal support beams, you should definitely pick up some 1x4s and have them cut to fit your frame. When I bought my bed, I assumed that since my bedframe didn’t come with any, I didn’t need them. Now I have a feeling that if my box spring had more support it would have taken longer to break. So I strongly recommend supplementing this fix with horizontal support as well.
