child safety seat
A seat used to protect babies and small children when riding in a car or other vehicle.
Also known as a child seat, baby seat, car seat, or booster seat.
In August 2024, the Japan Automobile Federation (JAF) announced that it was considering raising the recommended height for using child seats from under 140 cm to under 150 cm, leading to a meme in Japan that characters who have a height under 150 cm must now use a child seat, even if they're not a child.
