25 Best Booster Seats of 2019 – Harness, High-back, and Backless

Children grow fast! When your child has outgrown the weight and/or height limits for their forward-facing child safety car seat, it usually means that they’re ready for a booster seat. If you have used a convertible car seat that can support booster mode, it’s okay for you to still use that seat. But if not, you need to shop the best booster car seat for your kid at this time.

Booster seats are designed to keep your child safe before they can use the vehicle seat belt alone as a grown-up. They can help position the vehicle’s safety belt properly on your child through the shoulder and lap, providing the maximum protection to your child’s neck and chest in case of any accidents.

However, booster seats should be used when your child is ready for that. It’s not recommended to move them to a booster seat too early and keep your child in a harness car seat for as long as possible. Ask yourself below four questions before transition your child to a booster car seat:
> Is your child at least 5 years old?
> Is your child at least 40 pounds?
> Are the shoulder and lap belt available?
> Can your child sit properly the entire trip without leaning forward, slouching, playing with the shoulder belt, etc?

If you can answer “Yes” to all the questions, your child is safe to use a booster seat and you can shop one now.

But first, you should know which type of booster is the best option for your child? Generally, there are two types of booster seats: high-backed boosters, backless boosters. Some high-back booster car seats have the harness for safety, and some booster car seats can work as both. You can always pick up one for your child.

> Best Overall – Britax Frontier ClickTight Harness-2-Booster Car Seat

Britax Frontier ClickTight Harness-2-Booster Seat

If you’re finding the best booster seat with harness, the Britax Frontier ClickTight is a good consideration. It’s very easy to install and use, thanks to the ClickTight technique. This booster seat comes with 9-position harness to keep the children safe from they’re 2 years old until they weigh over 120 lbs, generally in their 11-12 ages.

The Frontier ClickTight is a forward-facing only car seat but can work with the harness and then transition to a booster seat as your child outgrows the harness weight or height limitation. When used as a forward-facing harnessed seat, the Britax Frontier ClickTight allows for children from 25-90 pounds, with a height limit up to 59 inches.

After your child reaches the 90 pounds weight limit or 59 inches height limit, you can simply convert the seat from harness to booster by safely tucking away buckles and straps within the seat. When using in booster mode, the Britax Frontier ClickTight has a higher weight and height limit, from 40-120 pounds in weight and up to 62 inches in height, making this booster seat the best option for large and tall kids.

The Britax Frontier ClickTight comes with a SafeCell safety system, including a steel frame, energy-absorbing base and patented V-shaped tether, to provide a better safety. The impact-stabilizing steel frame offers superior strength at the connection point to the vehicle for the car seat’s stability. The V-shaped tether minimizes seat rotation and keep your child stable by reducing forward movement during a crash. While the impact-absorbing base helps reduce the force of a collision. Plus, 2 layers of side impact protection provided by the deep energy-absorbing shell assures you that this car seat is safer for protection.

The good: The Britax Frontier ClickTight is a great booster seat with harness for safety. The SafeCell system consisting of the frame, base and V-shape tether ensures perfect protection, along with the 2 layers of side impact protection.

The broader range in weight (25-120 lbs.) and height (up to 62”) makes the Frontier ClickTight the best choice for tall kids, or allows a longer time in the belt-positioning booster seat.

When to Buy a Booster Seat

When your child outgrows the weight or height limit of the forward-facing child safety seat with harness, it’s time to convert to a booster seat. This generally happens during your child’s 4-5 ages, some big or tall kids may need a booster seat when they’re 3 years old because they reach the forward-facing seat limitations faster.

However, it’s not recommended to rush to move your child to a booster seat before they’re ready. And the child safety experts suggest to keep your child in a harness seat as long as possible.

Of course, you need to prepare the booster seat before your child needs it. If you have use a combination seat that supports booster mode, like all-in-one convertible seats, you don’t buy another booster seat anyway, just remove the harness and transition it to booster mode.

Things to Consider to Look for the Best Booster Car Seats

> Your child. You should always take your child’s weight and height into consideration before picking up an appropriate booster seat, after all, it’s them who stay in the car seat for a long time. Your child’s age is a useful reference, some booster car seats states their age requirements, like 2 years or 4 years old. If your child grows faster and taller, you might need a booster seat that features a higher weight/height limit and is great for big kids.

> Your budget. The booster seats are priced in a wide range. Some have a cheap price under $100, even under $50; a few costs hundreds of dollars with premium materials and additional features. But you can always find a suitable and safe booster seat within your budget.

> Your vehicle. Even the booster seats are not as bulky as convertible car seats, they come with different sizes and design. Some booster seats feature a wide width may not fit well for compact cars, especially those boosters with two built-in cup holders on both sides, they may not even fit 3-across.

> Growing with your child. As your child grows, they may not want to stay in a car seats with backrest, a booster seat that can be used in high-back and backless modes are preferable at this time.

How to Install a Booster Car Seat

xxxx

Types of Booster Car Seats

High-back Booster Car Seats

Also called Belt Positioning Boosters:  Comparing with backless boosters, they have a back and head support which goes up past the child’s ears. They usually require a lower minimum weight limitation than backless booster, and can be used for smaller toddlers. Many of these models allow you to remove the back and turn the seat into a backless booster – this option is very helpful for travel and for storage. You can check our top-rated 5 boosters with back and backless list at the bottom.

Belt-positioning Boosters with Harness

Featuring a similar design and belong to the high-back boosters, they function either as a car seat with a 5-point harness for children up to at least 40 pounds OR a belt-positioning booster for kids over 40 pounds. Transition from harness seat to a booster, you just simply remove the harness and use the vehicle’s safety belt to secure the child. However, the back is usually not removable on these models.

Advantages of high-back boosters: they usually come with an adjustable headrest that gives the best positioning of the shoulder belt for easy installation. The included headrest also provides necessary head support in vehicles with low seat backs. They are also better than a backless booster at keeping a sleeping child placed properly in the safety belt.

Backless Boosters

These are specialized cushions for children to sit on. The booster raises the child up off the vehicle seat for a better seat belt fit. Backless boosters all have seat belt guides which keep the seat belt over the correct place on the child’s body. Sometimes armrests serve as the seat belt guides, other seats use metal tubes or rings.

Advantages of backless boosters: They are more lightweight, compact, and less expensive than a high-back booster seat.  Making the children appear less “babyish”, they’re often preferred by older kids.

Combination/All-in-One:

There are three kinds of combination seats: one is the high-back booster seats with 5-point harness to ride smaller toddlers; another is the high-back boosters with a detachable backrest that can be removed when your child is ready with no back support; and the last is the one that combines all three features into one – harness, high-back and backless.

Advantages of combination boosters: They can use for a longer time through your child’s toddler to the youth ages and saves money to buy multiple booster seats.

Frequently Asked Questions

What age can a child move to booster car seat?

You can always find the minimum weight and height limitations of a booster seat in its product description, 30 pounds or 40 pounds for most booster seats. Generally, if your child’s weight or height falls into the range, you can move him/her to the booster.

Some booster seats may also state an age requirement, like the Britax Pinnacle ClickTight for 2+ years toddlers and Clek Oobr for 4+ years kids.

It’s strongly recommended to keep your child in a harness seat as long as possible before moving them to a booster seat, even if their weight, height or age has reached the minimum requirements.

When can kids stop using (sit without) a booster?

The answer depends on your child’s size and age, and the law in your state. Laws aside, kids aren’t ready to switch from a booster seat to seat belts until they’re at least 4 feet 9 inches tall and can pass the five-step test below – typically between ages 8 and 10.

To judge whether your child is ready to ride with a seat belt alone, test the fit of your vehicle’s belts from time to time. Buckle your child into the back seat without a booster seat, and consider the following:

Does he sit all the way back against the car’s seat?
Do his knees bend comfortably at the edge of the seat?
Does the lap belt naturally rest below his belly, touching the top of his thighs?
Is the shoulder belt centered across his shoulder and chest?
Can he stay seated like this for the whole trip?

If you answer no to any of these questions, your child should still stay in the booster.

Do booster car seats expire?

The short answer is yes. All child safety seats have a life-span after they leave the factory where they are manufactured. Most manufacturer have stated an expiration date on the seat, or mold it onto the shell on the back of the seat, some even introduce on their official site. We also include the lifespan for most booster seats in our list. If you can’t find it online, you can call the customer service for help to check. The expiration date of most booster seats is six (6) years from the date of manufacturer, if it is not specifically announced.

Can a 3-year toddler use booster car seat?

That depends. Generally, when your child’s size (weight and height)  meets the low requirements of a booster car seat, you can switch a booster seat for him/her. But it’s always recommended to keep your child in the last stage of forward-facing harness seat as long as possible. Or you can ride them in some booster seats with a 5-point harness, like the Chicco MyFit.

What is the law for booster seats?

That depends on the highway safety law of each state. Every US state has made the laws to require the driver or operator to ride the children with a child passenger safety restraint system, like a car seat or booster seat or travel vest. In most states, the child less than 57 inches in height are required to stay in a booster seat. This may vary based on each state’s specific requirements, and you can read our car seat laws to find the local of your state.

What is the safest booster seat on the market?

Actually, all the booster seats meet the federal safety standards and go through rigorous tests before it selling on the market. The safest seat is the one that fits your child’s age, weight, height and behavioral maturity, can be properly installed in your vehicle and will be used correctly every time the child rides in it.
