Best high-back booster seat

Which high-back booster seat is best?

​​Watching your child grow and hit new milestones is always exciting. If your toddler is getting too big for their car seat, it’s time for yet another change — transitioning to a high-back booster seat. If you’re looking for a high-back booster seat that can grow with your child and transition to a backless booster, the Graco Tranzitions 3-in-1 Harness Booster Seat is an ideal choice. 

What to know before you buy a high-back booster seat

Recommended age limits

Birth to 2 years old

When your child is first born until about 2 years old, they need to be in a rear-facing car seat. 

2 years old up to 65 pounds

When your child is at least 2 years old, they can transition to a forward-facing car seat. However, rear-facing is safer for children as long as they haven’t outgrown their seat, so there’s no need to transition your child if they aren’t ready.

At least 40 pounds and 35 inches tall

Children at least 40 pounds and 35 inches tall can use a belt-positioning high-back booster seat or backless booster seat.

Types of booster seats

  • Harness high-back booster seats are usually the same thing as a forward-facing car seat. They have a lower weight limit than the required 40 pounds to use a belt-positioning booster seat. However, even if some children hit the required height and weight limits of a booster seat, they are safer in a harness booster seat if they cannot sit correctly in a belt-positioning booster seat.
  • Belt-positioning high-back booster seats don’t have a harness, but instead, use a clip to hold the seatbelt in the correct position. 
  • Backless booster seats are only recommended once your child is tall enough that the seat belt correctly lies on their chest and shoulder without cutting into their neck.

What to look for in a quality high-back booster seat

Height and weight limit

The most important things to look at when buying a new booster seat are the height and weight limits. You’ll want to check that your child is big enough to use the booster seat while also ensuring they won’t outgrow it in the next six months or a year. 

Easy installation and portability

If you’re going to be installing the booster seat once and never moving it again, easy installation and portability might not be a big concern. However, for those who need to switch booster seats between vehicles or bring them on an airplane, it’s essential to ensure the seat is straightforward to install and light enough to move around.

Machine-washable cover

Kids always seem to get something all over themselves and everything around them. Whether it’s markers, food or even getting sick, a machine-washable cover will make it easier to clean up any mess.

How much you can expect to spend on a high-back booster seat

High-back booster seats cost $30–$200. The cost of high-back booster seats is primarily based on the brand and amount of features. 

High-back booster seat FAQ

Should you buy a used car seat if it’s in good condition and not yet expired?

A. Because there is no way to tell if a used seat has been in a car accident, experts recommend not buying used car seats. 

Where is the best seat in the car to place a booster seat?

A. Booster seats should never be placed in the front seats. The center seat in the back of a vehicle is considered the safest place for a car seat or booster seat. However, not all center seats are equipped for booster seats and some cars with bucket seats don’t have a center seat. For that reason, experts recommend putting your booster seat wherever it can be correctly installed. 

What is LATCH?

A. LATCH stands for Lower Anchors and Tethers for Children. It is a system designed to allow users to correctly install child safety seats in cars without having to use seat belts.
