Booster seats are designed for a child who has outgrown a forward facing restraint, and uses a car’s lap/sash belt. It is important that the sash part must cross your child’s shoulder and not run across their neck. Most booster seats come with a sash guide to guide the seat belt into the right position. Parents can, and still do, use booster seats as there is nothing preventing the use of a booster seat. Booster seats come in a number of variations a straight plain booster seat and a booster seat/ forward facing child restraint, and a rear facing forward facing and booster seat in one seat (There is only one Child restraint in the category which is the INFA LUXI Child restraint).
