I have an Ottoman Divan Bed that looks like this:
The top part is made of MDF, unfortunately the bit where it opens on the right hand side has sunken in a little bit in the middle right. As a result the edge of the bed is very squeaky on that side and the mattress feels lower.
Whats the best way to repair this MDF without damaging the fabric? Or atleast reduce the squeaking and make the MDF flatter?
