Unique design ideal for chin, neck, and shoulder comfort. Corduroy material has flap which hooks over chinrest, covers chinrest barrels, and lays on back as a shoulder pad. Foam inserts may be put in or taken out for height adjustment. Elastic bands secure rest to back. Relatively thin design allows it to fit in most cases without having to be taken off, an advantage for beginners. Instructions included. Large size fits 4/4 violin and 17-14" viola. Colors may vary.
