Another alternative is sheets of baking foil, just put a little against the chair (or where ever he pees the most)
Most dogs hate the sound of the urine hitting the foil and it either scares them or just makes them stop.
It could be the new rocking chair, or it could just be a behaviour change.
Give the deterrant a go first and see if that helps, if not then it might be time to re-train him to go outside.
