I have never been able to sleep comfortably without having a pillow between my legs while I sleep. It helps keep my back aligned and it also helps keep pressure from resting one knee on top of the other. With that said, I've always used a regular pillow, not a specialized pillow. When I saw this, I was very excited to have an actual pillow made to contour to my legs. Unfortunately it did not feel as soft as my regular pillow. It is easy to push down with a hand, but admittedly feels awkward between my knees.
