Very plush and comfortable but it's not supportive enough to hold your head up while trying to sleep on an airplane. I bought it because from the pictures it looked pretty tall and would hold your head well. I find my cheap blow up pillow to be more supportive. It might work better for folks with a thick neck (I wear a 15" collar).
Have juzt used the pillow on a trans-Atlantic flight and the pillow snugs up well to support your neck. A real neck saver. Could use just a little more cushion behind the head but overall well done. Think you need to be careful when taking it off or the velcro strip may seperate over time.
I am ecstatic about the pillow. My neck feels much better now when I travel via airplane, car, bus, or train. The only thing that is a drawback is the velcro closure which is a bit abrasive on the chin and neck. A double drawstring would be a vast improvement.
