Most neck pillows aren’t made for cars.
They were designed for plane seats.
Wide backs. Fixed headrests. Upright posture.
Cars are different.
Side forces. Seatbelts. Forward lean. Sudden stops.
That’s why head drop happens even when someone feels “comfortable.”
Why Traditional Neck Pillows Fail in Moving Seats
Support only works when it stays in place. In a moving car, most neck pillows don’t.
They tend to:
- Push the head forward when sleeping upright
- Provide too little side support to keep the head secure
- Flatten over time or shift their filling, losing shape and comfort
Padding alone can’t solve movement.
The issue is the support in motion.
Where Neck Pillows Get It Wrong
Most neck pillows assume:
- Still seating
- Vertical headrests
- Minimal side movement
Cars involve:
- Lateral motion
- Forward lean
- Seatbelts crossing the body
That mismatch is why comfort alone isn’t enough.
Plane seats stay upright.
That difference changes everything.
Napperoo SideRest Solves the Car Problem
Napperoo SideRest approaches the problem differently.
Instead of resting loosely around the neck, it aligns support with the body as it’s held in the seat.
That keeps the head from tipping forward or sideways when the car moves.
It stays where support is needed.
If you’ve felt that forward pull in cars, this is what fixes it.
