Having to take fill out of a pillow, then having to decide how much should be put back in to be comfortable is a stupid idea. Too much work! There should be a way to automatically adjust the height. Also, if someone else in your family wants to use pillow then the whole process has to be repeated. My pillow is still unused as the height is uncomfortable for my neck. Guess I'll have to find a cat or dog who won't mind what it is lying down on.
