I first tried an inflatable neck pillow (too stiff and scratchy) and then one
of those filled with styrofoam beads (too soft, it gave no support). Neither worked very well. This one I love. Made of memory foam, it keeps its firmness so that your head remains upright. It always molds right back into shape after being compressed. The deep blue cover is very soft. The cover has a zipper so it can be removed for laundering. It has an elastic strap so that you can attach it to a suitcase or carry-on. Because of this pillow I can now sleep on long flights.
