My physical therapist has this prone pillow. I love it.
My physical therapist has this exact product, which is why I wanted it.  It is very comfortable on the face, puts my neck into a neutral position that relieves pain, and I can breathe well.  Some reviewers have commented that they do not like the foam part by the chest, but I personally really like it.  It's like a cushion for my female chest and I think it's very comfortable.  Both cushions attach with velcro.  At physical therapy, I'm there for neck issues, so after doing the training program and exercises, they will put heat or ice on my neck with a TENS unit or comparable device.  Lying on my stomach instead of sitting up in a chair helps my muscles relax and get the full benefits of the modality.  Now I can do it at home after I complete physical therapy with my own ice pack and TENS unit.  I like to put my arms up on the sides by my head.  It's very comfortable, but I wouldn't want to lie on my face for any extended periods of time because of the pressure on my forehead.  You really start to feel it no matter what your face is in after 15 to 20 minutes.
