Stretch out the steams. Then cut only the threads and not the fabric.
Then add upholstery foam until you get the level of the cushion you like.
To seal the cushion side, use a needle and thread.

Remove the wood particles from the sofa to make it clean.
After you have cleaned the area, now you can install the new board in its place.
Let the glue dry for at least 3 hours.
