The ultimate trick for beaten and sunken furniture. I think all of us at home have even one battered furniture.
What you will need: an iron, some water and a towel. (You can use an old shirt that you do not need)
Pour water in stricken area
Now cover the area with a cloth
Set your iron to the highest temperature and iron upside down and cyclically your fabric to dry.
The wood will absorb water and swell with the result back to the original position. Repeat the process as many times as necessary.
As soon as you will repeat several times your wood will look like new.
