Fix the cover, pad the keys with sponge or foam plastic strips, wrap the piano face with felt, and wrap the corners with sponge or foam plastic. If the pedal can be removed, it should be removed. If it can't be removed, it should be put on a foamed plastic sleeve with grooves and then tied. If it is tied with a rope to facilitate lifting, put a thick sponge or cotton gloves on the place where the rope touches the corner.
