Causes neck strain because it's too bulky in the back. Pushes your head forward.
This pillow was too bulky. The back portion is so thick it pushes my head forward causing strain on my neck. Attempted using it on an international flight and winded up using it as a lumbar pillow (it worked nicely for that but not why I bought it) and used the flimsy airline pillow on my neck. Super disapointing. Not sure how so many others have had positive reviews. I can only assume they bought it as a gift for someone else or haven't actually tried using it in flight. Would not recommend.
