The back of my slipper chair has 2 support rails. Before I removed the fabric, I could see those rails pushing against the old fabric. The last upholsterer did not add anything between the fabric or the rails. The picture is of the back after fabric was removed, and before tear down was completed.

The chair back curves and I will add webbing and Dacron, but I'm worried the wood might still show through. What else can I do to make sure they don't, and to give it a nice round look?
