"Danish company RESTAHEAD has developed an alternative to the inflatable neck pillow most of us use in the hope of getting some sleep in an upright airplane seat. RESTAHEAD is a flexible and adaptable neck support that gently supports and relieves your neck muscles, giving you a real chance to get some rest."
"If you want to get through your flight without a stiff neck, the neck support from RESTAHEAD might be able to help."
"It can be adjusted so that your neck rests in a natural position and your muscles can relax."
"If your head tends to fall toward the flight attendants’ elbows in the aisle when you start to drift off, stop it with this neck support, which can be shaped to support both your neck and head."
