Over time and use, even the strongest bed frame begins creaking and sometimes bending. When this happens, you could go out and buy a new bed frame, or you could make the repairs yourself. Bed frames are comprised of basic parts including beams and joints. These parts are easily replaced, and your bed will be as good as new.
Remove the mattress from the bed frame. If you are fixing a queen or king sized mattress, you may want to have a helper for moving the mattress.
Look at the entire frame to see if you can find the break. Check the joint areas especially carefully, as the joints may become warped over time, causing the frame to sag.
Press down on the frame's supporting sides to feel for any weak spaces. If the frame is wood, listen for squeaking or cracking.
Disassemble the broken section of the frame at the joints using a screwdriver.
Replace any broken joints or frame beams on a metal frame. Coat any squeaking joints with beeswax on a wooden frame, and reassemble the frame.
Place the mattress back into position and test the bed.
