A booster car seat is the final stage before children move to a traditional seat in a car. Parents need to know when is the best time to transition them into a booster seat, and when to graduate into an adult seat. Guidelines include not only age, but weight and height are also considerations in the safety of your children.

Booster seats come in three models: backless seat, high back only, and a removable back (high back to backless). The goal of a booster seat is to provide height so the seatbelt can stretch safely across their body. It should be midway between the shoulder and neck, across the sternum, and lap belts should go across the upper thighs for maximum protection.

Large bones in these areas are able to better withstand the force from a collision – that is why they need to be properly placed on your child. If the seatbelts are not in the proper position, there is potential for serious injury.

Vehicle seat safety is continually changing from one child to the next. Parents should always ensure that their booster car seat has not expired, and are compliant when transferring it from one child to another.

Examine the Weight and Age Measurements

Booster seats tend to have a maximum weight of 30 lbs. for high back booster chairs, and 40 lbs. for backless booster seats. The minimum age requirement tends to be three years old.

Yet despite these minimum thresholds, it is not advisable to move your child to a booster seat until they have obtained the proper height and weight requirements of their current seat. For most forward facing five-point harnesses, this is 65 lbs.

The information on height and weight requirements can be found in the instruction manual for their car seat. Examining your child to ensure they are physically and developmentally ready to sit in a booster car seat and have a proper fit must be taken into consideration.

Boosters Should Position the Seat Belt Properly

Safety seat belts are used in conjunction with a booster seat to ensure optimal safety. They need to be able to position the belt properly on your child to provide the best restraint.

Highback boosters are recommended for everyday use as they position the shoulder belt better. They provide side-impact protection and are a more comfortable resting place should your child fall asleep while you are driving.

Parents are advised not to rush into removing the back too quickly on the booster. A backless booster seat should be used as a portable booster seat for travel and carpooling. If the vehicle does not have head rests or a low seatback, then highback boosters will provide your kid with head support.

Know Your State’s Laws on Booster Seats

Requirements vary from state to state regarding booster seats. Learn what the law says for your area before purchasing a seat. However, state laws don’t always convey best practices and can be based on weight as opposed to age/height. These two factors are the most important for proper belt fit and need to be taken into consideration regarding the safety of your child.

The rules offer general guidelines and often work for most children. However, when it comes to your child’s safety, everything needs to be taken into consideration.

The American Academy of Pediatrics recommends children use boosters until they are 4’9” and/or 8-12 years old.

Avoid Using Compact Boosters

While Bubblebum, Mifold, and Incognito may appear to be attractive and convenient, they are cumbersome to use. Each time your child needs to use the seat, the lap belt needs to be re-threaded through the loops.

Incognito should only be used for older children and Mifold may encourage slouching as there is no cushioning for the knees to naturally bend.

These seats should be used as a spare or just for travel. They often do a better job than sitting without a booster seat.

Traditional, lighter backless boosters are easier to use and are better for your child.

Do Not Use a Booster Seat on a Plane

They are not designed for airplane use, as planes have only lap belts. Should your child need one, parents can check their booster seat as luggage or rent one from a car rental company when you arrive.

Tips for Children Riding in Boosters

Children who have exceeded the weight or height requirements for a forward-facing car seat should be placed in a booster. They should remain in the booster until the adult seat belt can be properly fitted to their body.

Generally, this is between the ages of 8-12 years old or when they are 4’9”.

Your child has outgrown the forward-facing car seat when the following has occurred:

  • The top height or weight has been met from the seat with a harness as listed in the car seat’s manual
  • Shoulders rest above the top harness slot
  • Tops of the ears are at the top of the seat

Installation Tips

While using a booster seat, read the vehicle’s manual and car safety instructions for the seat before installing it. Seats often come with a plastic clip or guides to position the shoulder and lap belts.

Booster seats require both the shoulder and lap belt to keep children safe. You cannot use just a lap belt. It won’t prevent your child from injury.

If your vehicle only has lap belts, they will work fine for rear-facing only forward facing convertible models. The seat needs to have a harness in order for the child to be safe. A backless booster alone cannot be used for cars with only a lap belt.

Parents can also see if shoulder straps can be placed in their car, use a travel vest, or consider purchasing another car.

There are many things to consider when purchasing the correct booster seat for your child. The booster seat should be safe. Many highback booster seats come with side, rear, and front impact safety features in the event of a collision. Some have frames that will crumple like the hood of a car when impacted for shock absorption.

Highback chairs are recommended over boosters for cars. They offer the greatest protection in an accident, are completely padded, and are ergonomically designed. They support the child better and are safer.

Backless boosters are recommended if you are travelling from one car to the other for convenience. They are completely portable, comfortable, and have good storage. However, in an accident, they aren’t as safe as there is no padding around your child to absorb impact.

They also cannot be used if there are only lap belts as well. They need both lap and shoulder belts in order to work.

There are many features that make traveling in the car comfortable and practical for parents. Easy to clean cup holders and washable fabrics make clean up effortless. Storage areas keep things neat and tidy.

Some seats are created with a slim fit. This allows parents to place three children across the middle of a car, or along the backseat. Previously, car seats were too bulky to accommodate this. Now, the seats are slenderer and the cup holders fold in to create additional room. The backseat is no longer cramped.

When selecting a car seat, make sure that it fits your child’s height and weight. These are the most important factors in keeping your child safe. While the age requirements are a general guideline, the other two factors are the real indicators as to whether your child is ready for a booster seat.

Many seats also come in convertible models. They are designed for newborns up to the age of ten. While they save money in the long run, parents may want to make sure that they continually meet safety standards each year as they are always changing.

All car and booster seats come with an expiration date that parents need to watch out for. If caught, there may be some repercussions as the seat could be deemed as dangerous.

Parents should pick a seat for their budget, and with their needs in mind when picking out a booster seat. Take each variable into consideration, and picking a seat will be effortless.
