A very kind reader just discovered this cd player for her elderly mother:
It is mounted on the wall. Once the cd has been placed inside, the user only has to pull on the cord to operate it! The person who recommended this said her mother lives in an assisted-living facility. The cd is changed periodically by the staff. She wrote a large sign that reads, "To hear music, gently pull on the cord." Click on the link for more information and photographs of the unit.
