Trust me.I've either tested or researched every single neck pillow out there. And this is the only one that actually works.See, a true neck pillow must do two things: 1. Prevent your head from dropping forward and 2. Keep your head from falling to either side. And the ONLY way to do both is to somehow attach your head to the airplane seat.So regarding this review: It’s like wearing a headband that attaches to the seat with a big piece of velcro. This way your head stays motionless. The nice thing is that they’ve incorporated a perfectly black super-comfortable eye mask as well.(There is another style that could also work as a neck pillow but it has never been brought to market. It’s called the Head Hammock and it’s based on the same idea: only that one holds your chin instead of your forehead.)Photo from Airbus A350-1000 Qatar Airways Economy.It really works.Remember to tell the flight attendant to wake you for meals or else you might sleep all the way through.
