When it comes to picking a booster seat for your child, you can’t go wrong with any of the models we’ve talked about here! It all depends on what needs you and your children have in a booster.

Booster Seat FAQ’s
Do I have to use a booster seat? Why is it so important?
Many parents let their kids sit in the car with the regular seat belt once they’ve outgrown their convertible car seat. However, this is a very dangerous mistake! Many children, even pre-teens, are still too small to be sitting in the vehicle seat without a booster seat.
The purpose of the booster is to elevate children to a height that allows the vehicle seat belt to be properly positioned across the child’s lap, hips, and chest without digging into their neck. Many children require a booster until they are about 4 feet 9 inches tall, which is normally between ages 8 and 12.
Many booster seats, such as the UPPAbaby ALTA, ensure you have proper seat belt positioning that prevents a phenomenon known as “submarining“. *Submarining is when small children slide under the lap belt during a collision. This can lead to excessive injury and death.
It’s always better to be safe than sorry. Although kids like to be independent and sit in the car without a booster as they get older, using a booster for kids that just aren’t quite tall enough can save their life or save them from unnecessary harm in the event of a crash.
When should I transition from a convertible car seat to a booster seat?
Keep your child in their convertible car seat as long as possible as it will offer the best protection if you get into an accident due to the 5-point harness. However, it’s important that you familiarize yourself with the car seat manual and transition your child to a booster once they reach the height or weight limit of the seat, whichever comes first.
An easy way to know if your child has exceeded the height limit is to check the harness position. If the car seat has the harness in the utmost position and the child’s shoulders are still above where the shoulder straps come out of the car seat, they are too tall for their car seat and it is probably time to transition to a booster.
What are the differences between a harness mode booster, high-back booster and a backless booster?
The three main booster modes are harness mode, high-back belt positioning mode, and backless mode.
Harness mode is found in boosters with a 5-point harness, similar to what you’d find in a convertible car seat. Boosters with this mode allow you to use the seat as your forward-facing car seat from a younger age, and then transition to booster mode with the vehicle seat belt later on. (The Britax Grow With You ClickTight Plus is the only booster in this comparison article with harness mode.)
High-back belt positioning mode refers to the booster mode that has a tall seatback and uses the vehicle seat belt to keep your child in place rather than an incorporated harness. High-back belt positioning boosters are great for kids that are just growing out of their convertible car seat. This is because this mode ensures the vehicle seat belt is positioned properly across the child’s lap, hips, chest, and shoulders for optimal safety.
Backless mode refers to boosters that do not have a seat back attached. These are often used for older kids that just need a little extra height to ensure the vehicle seat belt is positioned properly.
Booster seats in general, whether with or without a back, will help keep your child safe in a car accident. However, high-back boosters are recommended if your vehicle seats don’t have a headrest or if the vehicle seat back is not very tall. The back rest that the boosters provide in these scenarios offer essential support that keeps your child’s neck and head steady and safe from harm in the event of a crash.
Backless boosters can be used for vehicles with headrests or taller seat backs that already offer added neck protection.
Always refer to your booster manual for how and when to use each mode.
How should the headrest and seat belt be positioned in a booster seat?
We recommend always reading the car seat manual for instructions on how to best install and position the headrest to ensure proper seat belt alignment on your child.
As a general guide though, the headrest should be installed at a height that allows the shoulder belt to be positioned directly in the center of your child’s chest and shoulder. The seat belt should not be digging into your child’s neck. The lap belt should be snug across the child’s thighs.
What if my child is embarrassed and feels “too old” for a booster seat?
Due to the fact that many parents stop using boosters before they should, some kids will notice and wonder why they have to use a booster seat if their friends don’t. This can cause them to feel embarrassed when they’re the only one still in a “car seat”.
If your child is feeling this way, sit down with them and explain to them that you want them to be safe and that a booster seat allows them to be as safe as possible.
Another great option is to let your child pick the color of his booster and then show him how to get buckled. Giving your children freedom and independence helps them feel more excited and less anxious about using a booster.
Also do your best to refrain from calling their booster a “car seat” as this can make some children feel like babies.
