Could I get some suggestions for a very simple CD player?

I am looking for suggestions for my boyfriend’s mother who has early stage dementia. She is wanting a CD player. Just one of those small ones. But she has a hard time figuring out how to make it work.
If there could be one with maybe just a play button and a stop button, that would be perfect. She would only need to put one cd in at a time and wouldn’t care about skipping around.
She definitely wants a CD player and not something for MP3. She is adamant about that.
