Best Britax booster seat

Which Britax booster seats are best?

Kids grow fast, and during those early years, it seems like you’re constantly having to buy new accessories and equipment. One of those pieces of equipment that can creep up on you is a booster seat, which you’ll need to purchase when your child outgrows their car seat. 

Safety is a priority, and you’ll want a product you can trust. Britax is a brand known for making quality products, and they have a line of booster seats that can fit your needs. The best booster seat for you will be determined by the age, height and weight of your child. However, an all-around top pick is the Britax Grow with You ClickTight Plus Harness-2 Booster.

What to know before you buy a Britax booster seat

When to switch to a booster seat

Every child is different, but you want to keep your child in a traditional, forward-facing car seat with a harness until they surpass the height and weight limit. That’s when they should graduate to a booster seat

Laws vary per state, but some require a child to be seated in a booster seat until 8 years old. Also, keep in mind that most car seat belts won’t properly fit passengers any shorter than 4 foot 9 inches, so a booster seat is necessary until your child meets the height requirements.


You always want to put your booster seat in the back. In some states, it’s illegal for a child to sit in a booster seat in the front. If the center rear seat has a three-point seat belt, that is the safest place in the car for a booster seat. However, if it only has a lap belt, it’s best to opt for either the left or right rear seat. 

What to look for in a Britax booster seat

Types of booster seat

  • High back booster seat: This is similar to a forward-facing child seat, and sometimes, they are one in the same. Some have a three-point harness, others a five-point harness and some can be used with the seat belt. 
  • Backless booster seat: This is exactly what it sounds like: a booster seat that doesn’t offer back support. It’s the next step up when your child outgrows a high-back booster. These are ideal for older kids, and they are less expensive. 

Machine washable cover

Kids make a mess, and that includes when they’re in the car. Luckily, you can at least keep the booster seat clean because most Britax models come with a detachable cover that is machine washable. 

How much you can expect to spend on a Britax booster seat

A Britax booster seat is on a mid- to high-level price point for booster seats. Depending on the features, benefits and size of the booster seat, it can cost you between $75-$350.

Britax booster seat FAQ

Can my booster seat be passed down to my other children?

A. Yes! But safety standards change, and booster seats have an expiration date of about 6 years. You should always check the sticker on the side of the booster seat to verify the exact date it expires. If you are under the 6-year mark, the seat has never been in an accident and it is in good shape, it is safe to pass down to your other children.

Should I purchase a used booster seat?

A.  Maybe. A used booster seat should only be purchased if you are very familiar with the previous owners and absolutely positive the seat was not involved in any accidents. If you cannot verify that information, we do not recommend you purchase a used booster seat. It’s not worth the risk.
