The sofa sat up to make a noise.
There are three main reasons why the sofa sits up and makes a noise: the sofa wooden frame is loose and unstable; the snake spring on the sofa's bottom rubs against the wooden frame to make a noise; and the leather rubs against each other to make a noise.
1, wooden frame loosening noise, first distinguish the place where the noise is produced. If the wooden frame is not loose enough to make a sound, see clearly where the sound is, add nails and wooden cubes at the sound place.
2. The sound produced by friction between the snake spring and the wooden side can be pulled away from the snake spring where the friction occurs, or the wooden side can be cut off with a knife until there is no sound on the seat.
3. Leather rubs against each other to make a sound. Leather protectant can be applied to the rubbing place to make the leather soft and smooth, so that there will be no rubbing sound.
Sofa installation is not solid, loose
1. Sofa loosening is mainly due to: Sofa installed in some places where the screws are not tightly screwed, resulting in the use of the sofa for a period of time and loosening phenomenon; or the sofa hole is too large, leading to screw down, resulting in loosening phenomenon; or sofa in the transport process, by heavy objects squeezing or bumping caused loosening.
2, if the screw is not tightened, screw the screws or reinforce them with self tapping screws.
3. If the hole is too big to cause loosening, first loosen the down-to-earth screw, drill a smaller hole with a nine-centimeter splint or wooden square, put it on the down-to-earth hole, and then screw the gasket.
