Best Booster Seats

Verywell / Sabrina Jiang

Car seats can be confusing, to say the least. There are so many different types and varying guidelines, so it can be really tricky trying to figure out when to move your child to a booster seat (or even know what a booster seat is).

Booster seats are designed to sit a child up high enough in a seat so that they can safely use the car’s seat belt. However, since it’s safest to keep kids in a five-point harness for as long as possible, there are a lot of forward-facing car seats that will convert into high-back booster seats when your child is big enough to transition.

When you first start shopping around, remember safety is of the utmost importance, and you should consider how the type of booster seat you choose will fit in your vehicle. And, don’t forget to think about how your child feels about the booster seat, whether it’s easy for them to climb in and out of, or if they’re genuinely ready for the big switch. 

We’ve collected some of the best booster seats on the market to help you narrow down your search a bit.

What is LATCH?

Most cars manufactured after September 1, 2002, are required to include a LATCH system (Lower Anchors and Tethers for Children). Designed to make installing car seats safe and less complicated, this method allows caregivers to safely install car seats using anchors as opposed to the car's seat belts.

What to Look for in a Booster Seat 


Once you’re confident that it’s time to make the move, keep in mind that every booster seat sold in the US must meet all federal safety standards so, no matter what, when they are installed and used properly they will keep your child safe. That being said, specific designs vary and you’ll want to choose the one that is best suited for your vehicle, child, and your family’s lifestyle. 

Something to consider is the size of your vehicle’s backseat and how many car seats/boosters you’re trying to fit. You may need a seat that is more narrow in order to safely install the seat. 

Alisa Baer, MD Pediatrician & Co-Founder of The Car Seat Lady, LLC, says that one of the features in highback boosters that kids love most is one parent may want to skip: armrests. This is because their design alone helps to “eliminate [a] very common” safety concern. She explains, “Studies show that nearly half of all boosters are misused in one specific way - where the vehicle lap belt is routed over the top of one or both of the booster’s armrests. This is particularly dangerous as the lap belt is directly over the child’s soft belly, which is exactly where the lap belt should never be". Choosing a seat without armrests helps to eliminate this common installation error.

The most important thing you will need to consider when choosing a booster seat is your child’s height, weight, and general readiness to transition from a five-point harness front-facing seat to a booster seat. A representative from the National Highway Traffic Safety Administration (NHTSA) tells Verywell Family that parents should “keep your child in a forward-facing car seat with a harness and tether until he or she reaches the top height or weight limit allowed by your car seat’s manufacturer.”

However, their maturity also plays a role in whether or not it’s time to transition. “The biggest mistakes we see parents make is switching to a booster seat before the child is ready and moving out of the booster seat too soon,” a representative from the University of North Carolina (UNC) Highway Safety Research Center says.

“Booster seats are intended for older kids who have outgrown the limits of their harnessed car seats and are mature enough to sit correctly in a booster seat. For many kids, this may not be until they are 6 years old or older".

Ease of Use for Child

By the time your child is in a booster seat, they’re more independent, so consider how easy it will be for them to climb in and out of the seat and whether or not they can reach the seatbelt to properly click it in and out as needed. 

Additionally, you might want to have your child help you find the best booster for them. “Kids who are old enough to ride in a booster seat are also old enough to have an opinion about some of the comfort and style choices. Kids are more likely to ride in a booster seat without complaint if they have had a voice in choosing the seat" says the UNC Highway Safety Research Center.

This doesn’t mean you don’t have to relinquish total control, though, do your research and narrow your choices down to two or three designs that meet all of your needs, and then have your child choose which of them they like best. 

Booster Type

There are four different booster seat types, according to the NHTSA: a booster seat with a high back, a backless booster seat, a combination seat, and an all-in-one seat.

High Back

  • Lifts the child up so the vehicle’s seat belt fits properly (NHTSA)
  • Provides head and neck support and can minimize whiplash (NHTSA / Dr. Baer)
  • Ideal for vehicles that don’t have headrests or high seat backs (NHTSA)
  • Kids sit with less leaning and squirming as opposed to backless (Dr. Baer)


  • Boosts the child’s height so the seat belt fits properly (NHTSA)
  • Ideal for vehicles that have headrests (NHTSA)
  • Does not provide support to child’s neck and head or protect against whiplash (NHTSA / Dr. Baer)
  • Good for any time a child is riding in someone else’s vehicle; taxi, Uber, friend’s parents, family member, etc. (Dr. Baer)
  • Good for kids who have outgrown their highback booster but have not passed the five-step seatbelt test (Dr. Baer)
  • The vehicle’s seat is too narrow to fit a highback booster (Dr. Baer)


  • Transitions from a forward-facing car seat with a five-point harness to a highback booster seat (NHTSA)
  • Good for parents looking for a seat with longevity (NHTSA)
  • Has all of the advantages of a standalone highback booster seat


  • Converts from a rear-facing car seat to a forward-facing car seat with harness to a booster seat as the child grows (NHTSA)
  • Some, not all, will convert into a backless booster seat
  • Offers all of the benefits of a highback booster and a combination seat
  • The best option for longevity


When can a child stop using a booster seat?

The American Academy of Pediatrics recommends children stay in a booster seat until they are big enough for a seatbelt to fit them properly and/or once they’ve reached the height or weight limit for the booster.

When do I switch to a booster seat?

The longer your child wears a five-point harness, the better, according to the American Academy of Pediatrics, so that means you want to keep them in one until they reach their forward-facing car seat’s height or weight limit (whichever comes first).

At a minimum, children should be at least five years old before transitioning to a booster seat, assuming they haven’t met their car seat’s height or weight limits before then.
