I use it as everyday pillow; I no longer use regular-size pillows because of cervical problems and this pillow works very well. I have tried shredded foam and polyester-filled pillows, in search of resilience, softness and support. They all work well at firts and then the filling gathers at the two ends and the center flattens. No such problem with this pillow. It keeps its shape. By the way, I don't know why they say it has a "zippered carrying case" unless they mean by that the ordinary zippered plastic bag it comes with? However it has a nice zippered cover of some kind of velvety material. Would definitely recommend.
