Sofa - if unwanted noises occurr
Ho to fix a squeaky bed
Our sofas contain a number of components that can cause noises. One that is easy to derive and fix is the creaking of the Nozag springs. The noise is caused by the friction between the spring and the bracket.
Here's what you can do
Turn over the sofa to reach the springs.
Check the springs one by one by pulling them quite hard. You will hear if it stays quiet or squeaks. Make a note of which and how many springs make noise and where they are located.
