First off I never write reviews- so please believe me this has earnt it’s 5 stars. I also never sleep on planes until now! I snoozed my way through both 7hr overnight legs of my trip. It is incredible!You may look like an idiot, but direct feedback from my envious economy seat mates is by the end of it you are going to be anything but.It’s really straight forwards to use, easy to get in/out of. Fully stops any head lolling without any need for constant readjustment or overheating. It holds you head securely but gives your body freedom to shuffle. With this plus noise cancelling headphones it’s like a full sensory deprivation chamber in a seat. I plan on never taking a plane trip without it again
