Cracks And Splits

After removing the cushion and mattress out of the sofa, turn the sofa upside down. Check all the wooden parts of the bed frame if there is any crack or split or not. The splintered and cracked wooden frame makes the sofa loose. It starts sagging because of it, and your sofa gets unstable too. You can fix sagging as well.

Joints are where the sofas wooden parts are kept together at 90 degrees with bolts and staples. Now the problem can be in this part of the sofa too, check them thoroughly. With heavy use, the screw hole gets stripped and loose. They don’t tighten up anymore, no matter how much you try with a screwdriver. Loose screws mean loose frames, which result in a sagging sofa bed. Now to fix this stripped screw hole in which the screws will keep sliding, you need glue. Inject glue in the holes and let it dry. When the glue cries off, cut the extra part with a coping saw.

Metal Parts
