The Best Harness Booster Seats Currently on the Market: Top 11 Choices

Graco Tranzitions 3 In 1 Harness Booster Seat - Best Booster Seat with Harness

Our best pick choice goes out to the Graco Tranzitions.

If you are familiar with the previous Nautilus version of the seat, you will love the improved Graco Transitions booster seat.

The luxurious and narrow design allows you to install several car seats in the backseat.

This forward-facing booster seat is one of our favorite models when it comes to traveling. It's just the right weight, suitable for parents on-the-go. Plus, you won't have to splurge on it since it has a budget-friendly price.

The Graco Tranzitions 3 in 1 seat has a unique design.

Not only do you use it as a harness booster and a belt-positioning seat, but you can also use it as a no-back booster when the time is right.

That being said, the booster is equipped with SimplySafe to adjust the harness system that changes to the harness and the headrest in eight height positions.

The seat contains blow-molded plastic, which volumes down the seat's weight but still keeps the insides comfortable.

You might think that it's not as comfortable as heavily padded seats, this design proves to be an excellent energy absorbent component. 

Reportedly, the booster seat works impressively well in car crashes.

Several parents who had the experience commented that the seat was intact after the crash. However, you cannot use the seat from that point on. Always replace it after a collision of any sort. 

Depending on your vehicle, the installation can be tricky sometimes.

Since the booster is relatively narrow, the shoulder belt path is installed high up. Cars with a shoulder belt on the side or high up on the seat-back will experience some issues. 

Furthermore, the seat is equipped with a latch for top tethers and the lower anchors.

But, be aware that this is only suitable for children weighing less than 45 pounds, who need to be secured in a harness mode. 

  • Machine washable pad
  • Car crash tested
  • 3-in-1 seat
  • Tricky installation with shoulder belt 

Chicco MyFit Harness + Booster Car Seat - Best Side Impact Protection

The well-known brand Chicco has earned the respect of its trustworthy customers worldwide. Even though some consider the products "too high," we feel that price justifies the quality of the product.

Here is why you should consider the MyFit Harness+Booster Car Seat.

The Chicco model is a favorite since it's packed with features that we all love to have in a booster.

Starting with the convertible car seat function, this booster is suitable for children who require a 5-point harness and for older ones secured via a seat belt.

When using the booster in a forward-facing position with the harness, weight requirements are 25 to 65 pounds. On the other hand, the belt-positioning booster can be used by kids weighing 40 to 100 pounds.

The benefits of using this kind of booster lie in its ability to accommodate a younger audience and those who are transitioning to a backless booster.

Uplifting comfort is a big plus on boosters.

The reclining function of the Chicco high back booster is not necessary for safety, but it's a must-have when it comes to comfortable rides.

There are four reclining functions of this model, and they can be adjusted to a preferable level. A padded harness with one pull-tightener will keep them comfortable and safe in their seats for growing toddlers.

As for safety, the Chicco forward-facing car booster takes the win.

The Duo Guard 2-layers shell protects your kids with the energy-absorbing layer and a side impact protection.

Your kid will be secured safely with the use of a Lock-Sure belt-tightening system that provides a snug fit during long rides.

  • Latch system

Britax Grow with You ClickTight Harness-2-Booster Car Seat - Best For Bigger Cars

Britax acclaims one of the strongest reputations in the car seats and booster world.

By continually pushing the boundaries on the innovations, Britax delivers one of the most impressive boosters/car seat combinations.

This booster can be used as a forward-facing for children between 25-65 pounds. It offers a 2-point harness that accommodates the children's growth.

The great thing is that you won't have to splurge on both the car seat and a booster. Britax has it all.

When your kid is ready for a high back booster, the car seat transforms into one and offers all the support and comfort a kid needs.

The high back booster mode offers a 22" belt path that is suitable for children up to 120 pounds.

The Grow with You seat is packed with safety features such as Click Tight installation and side-impact protection when it comes to safety.

You won't even have to worry about adjustment; the booster offers a harness that is quick to adjust and a multi-position recline technology designed to keep kids comfortable.

One of our favorites is that you don't need to take out the harness when you plan on using the seat as a high back booster.

Simply tuck the belt straps in the seat pocket and switch to a harness mode when you desire.

This has proved to be quite beneficial, especially if you have two toddlers by your side that require a seat switch each time.

The tricky part of the forward-facing booster seat is that it's not suitable for smaller cars or three across car seat installation.

It is on the lightweight and narrow side, but the expandable cup holders make it challenging to fit into a smaller vehicle.

Graco Nautilus 3 In 1 Harness Booster Seat - Best Safety Features

We already talked about the upgraded version, but what about the original one?

Graco Nautilus car booster seat is a 3-in-1 system with a whooping 120 lbs weight capacity.

Still, keen on the upgraded version? Let's see why you should consider this one as well.

Safety First: This booster has caught our attention mostly due to the safety features and capability to hold your loved ones snug throughout the ride.

It meets all the necessary requirements and even passes the New Car Assessment Program (NCAP), proving it can withstand a car crash.

The safety is that much enforced by the energy absorbing layer and a 5 point harness system that keeps children in place during bumpy rides.

With its steel frame, the Graco car booster seat is bound to serve you for a long time. However, even though it is durable in construction, it's pretty bulky if you ask us. Taking it out of the car was quite the chore.

The 3-in-1 system is designed to fit the rear-facing babies to toddlers who need a backless booster seat.

When it's time to dismantle the seat, you can follow the detailed manual instructions and switch the mode within 5 minutes.

Getting the harness belt to loosen up and adjust was pretty easy. However, tightening them is where we struggled the most. But, the good news is that you do not need to rethread the belt.

For anyone who dealt with rethreading, you know the hassle of it. So, having a booster that requires an easy system of adjustment is truly a relief.

The bottom line is that it's one of the best choices for a 3-in-1 booster seat. The safety features, comfort, and style are all on point.

So, if you are deciding between Nautilus and Graco Transitions, we hope we solved your dilemma.

  • 5 point harness

KidsEmbrace 2-in-1 Harness Booster Car Seat - Impeccable Design For Marvel Fans

Are you willing to put a unique spin on the conventional booster seat for your youngest Marvel fan?

The Kids Embrace harness booster seat is a safe and comfortable option bound to make every ride as fun as it gets.

Be honest, how many times did your kid refuse to get in the booster seat?

With KidsEmbrace, you will have no such problems. The brand offers a variety of different designs, from Disney characters to Nickelodeon ones.

According to NHTSA's recommendations, kids should remain in belt-positioning seats until they reach 57 inches in height. This booster seat allows children from the age of three and up to use it. One of our favorite features is the functionality of the booster.

It converts from a harness to a high back booster as your kid grows.

You can either use it as a forward-facing seat, built for children weighing between 22 and 65 pounds or as a convertible car seat belt positioned seat.

However, it cannot transition to a backless booster. (If you need one, we have a separate article on that topic here).

Even though the attraction is unique, the KidsEmbrace harness booster is entirely safe for children. It meets all the necessary USA safety requirements by IIHIS.

With the patented energy absorption layer, the booster provides optimal safe rides and side-impact protection technology.

The high back booster offers a 5 point harness with three harness positions designed to fit your child's age, weight, and height.

Finally, we would not recommend this booster if you have a smaller car. The seat is quite cumbersome and does take up space in the back seat.

For all of you with extra backspace, this will be a great purchase.

  • Machine washable pad
  • Impressive design
  • Convertible car seat booster
  • Heavy
  • Cumbersome

Evenflo Chase Harnessed Booster - Comfortable Companion For Long Car Rides

The Evenflo Chase harnessed booster seat is a favorite among parents who value safety, style, and comfort for their kids.

It will follow all the full adventure rides through childhood and keep the young ones safe with many features and accessories.

The harnessed booster seat is thoroughly tested for structural integrity, ensuring your child is safe in vehicle transportation.

As it should be with all booster seats, the side impact protection meets all the applicable federal safety regulations.

Having in mind that the booster is tested for rigorous crashes, you can rest sure knowing kids are safe in the back seat.

The model offers a 5 point harness system that secures children up to 40 pounds. After the child has surpassed this weight, your next step is switching to a booster seat.

Most of the parents commented that the installation of this car seat booster is easy and straightforward. The lightweights of the product do the job that much easier.

We bet that most of you will be thrilled to know that the Evenflo Chase is quite the budget-pick compared to other booster seats.

It's considered the best pick for those who want to cut down on expenses at such a low price but still have a durable and safe booster.

The determining factor of whether children will like the booster is most definitely comfort.

The Evenflo booster offers ComfortTech technology. Moreover, the seat is constructed from three separate layers that help ease the pressure points as the kid grows.

The seat also offers four different buckle positions.

If you want to use it as a belt-positioning booster, know that the buckles are fit to accommodate the exceeding growth.

  • Impressive comfort
  • Lightweight
  • Accommodates to the kid’s growth
  • No rear-facing mode
  • Light padding

Cosco Finale DX 2-in-1 Booster Car Seat - Best For Smaller Children

2-in-1 car seats that offer both the harness support and seat belt safety have been all the rage over the past few years. However, they are known for their high prices

The budget will not stop you when it comes to the Cosco Finale booster car seat.

With a $60 price point, the forward-facing booster seat will fill all of your expectations and support your little one in the best way possible.

What surprised us the most is the minimal weight of 30 pounds for the harness mode. This weight limit is suitable for tinies passengers who are not just yet ready for a booster seat mode.

What might present an issue is the only one set of the crotch buckle mode. This could be an issue for smaller kids, leaving them with a bit of extra space. However, it's a perfect fit for bigger ones.

Also, the harness mode seems a bit shorter for kids weighing around 65 pounds. However, considering this is the limit weight, you might want to convert the harness setting into a booster seat belt.

As for the high back booster mode, the belt guide is tricky to install in some vehicles. 

The reported problem regards the belt not retracting. Luckily, you only need the belt guide to adjust the right fit. Parents didn't even have to use it most of the time.

When your child reaches age 6 or 7, he/ she will probably need another booster since this one does not have an adjustable headrest.

You can do so using the latch system for the installation but only for children weighing around 50 pounds.

Please consult with the vehicle manual to determine the right way of securing the seatbelt.

  • Affordable
  • Convertible car seat booster
  • Suitable weight limits
  • Installation can be tricky 

Evenflo Maestro Sport Harness Booster Car Seat - Best Car Crash Safety Tested

The booster seat by Evenflo Maestro Sport is not as glamorous as some of the other expensive models, but it will surely deliver the best quality for a safe ride.

You can select from a few color patterns and make sure your ride is just as stylish as comfortable.

The Maestro Sport forward-facing booster is designed for kids who have outgrown the rear-facing seats and are now ready for adequate protection.

Even though you will get a few years out of the use, the height selection is not as generous as with other models.

Our main issue with this booster car seat is that it offers only one belt guide position

This can be tricky when your kid is in the transitional phase regarding height. The headrest is not adjustable, and it does the job that is much more problematic.

It means as soon as your kid turns 6 or 7, it's time to get another seat. This is not in all cases, but many parents commented that they did not get further use out of it.

All Evenflo seats have been tested for 2x federal car crash safety. This includes side impact protection, flammability, temperature alterations, and structural integrity.

The latch system can be used for children up to 50 pounds, meaning it can sometimes serve for belt positioning rides. However, some had problems securing the latch system as well as tightening the harness.

We suggest keeping the manual handy at all times to track the child's height. Since the height and weight limitations are pretty low, chances of outgrowing a booster are high.

All in all, this is a suitable budget-friendly option. If you are carpooling or leaving the kids for a weekend at grandparents, this can be a great backup booster.

  • Cup Holders

As you can see, the 5-point harness offers additional stability and security for your kids while on the go. They will move freely but cannot slip away or get hurt, and the seat will be stable and secure as well.

So, the belt won't limit or repress them, and they will be more comfortable while wearing it.

Mess is an unavoidable part of every journey. Thus, your kids can easily spill their drinks and snacks all over the seat and vehicle seat.

But, that's not a reason to worry since you can easily remove the seat pad and wash it in a washing machine. Next, you can leave it in a dryer to fully dry and be fresh and ready for more extended use.

Buyers Guide for the Best Harness Booster Seat

1. 5-Point Harness Vs. 3-Point Harness: Which One Is Better?

best harness booster seats 2020

You want a harness booster seat, but you are still debating whether a 5-point or a 3-point harness is better? Let's sum it down.

The whole logic behind the issue is the more straps, the merrier.

A 5-point harness is designed to protect the kid's neck, shoulders, and hips. Two straps are covering the hips, two shoulder belts, and one between the legs.

On the other hand, a 3-point harness booster lacks the two straps that protect the hip area.

Right then and there, you can assume that 5-point booster harness car seats are better for optimal protection. And guess what? You're right.

There have been numerous situations where a kid simply wiggles their way out of the strap. However, the odds are less likely if you secure them in a 5-point one.

2. What Are the Benefits of Harnessed Booster Seats?

Getting harnessed booster car seats is not only a smart decision, but some state's car seat laws also require it.

Booster seats with harness are designed to keep your little one in place during bumpy rides.

By restraining kids in harness, the crash's effects will less likely strike them, since this technology works towards protecting them as best as possible.

During a collision, the movements are limited. 

Any applied force will be spread into the booster seat, covering the kid's soft areas such as the abdomen.

3. Weight and Height Requirements

As you can notice, most of the harness booster seats have a threshold of 40 pounds as the ultimate weight limit. But, this is not the situation for all of them.

Booster seats with a harness can sometimes secure around 65 pounds of weight while still keeping the child snug.

We recommend you wait a bit before turning your harness booster car seats into a convertible car seat with belt restraint.

Always read the car seats manual to check the right weight and height for a seat belt booster.

According to the NHTSA, children should remain in a harness seat until they are at least five years old.

If the child wiggles and slips out of the seat belt booster, it's not the right time to move from a harness one.

Once the child overgrows the harness seat, he/she is ready for a seat belt booster. As long as you install it adequately, you have nothing to worry about.

4. Safety Requirements

Picking the best harness booster seat goes beyond just having cup holders and colorful designs. Always check if the booster seat meets all the necessary safety requirements.

For starters, check if the seat follows The National Highway Traffic Safety Administration's standards.

Then, inspect if the booster is still in good shape or expired. Yes, booster seats have a limited life span.

Just like regular car seats, the booster can usually last up to 6 years or more.

The best solution is to buy a new one, but if you are going for a second-hand one, make sure it hasn't been in an accident or expired.

5. Installation

best harness booster seat for 4 year old

Installation is the key if you want a stress-free ride.

Though it can't always be guaranteed, you can choose from two options: The first one is installing the booster by using the vehicle's seat belt. The second is using the well-known LATCH system (tethers and lower anchors).

The system works pretty quickly, and it's recommended as the safest installation route. You need to attach the seat to the anchors in the back and the ones behind the seat.

Don't worry if you don't get it right the first time. 

The best thing is to practice several times before your child uses the booster. In this way, you avoid the stressful situations of installing the seat in a rush.

Here is a link we hope you will find helpful.

6. Accessories Make All the Fun

You will find a lot of harness booster car seats on the market that have extra features. They are not essential, but it sure is fun to have them as an additional feature.

Our favorite one is the cup holders.

Of course, we cannot use them enough for being a nifty little helper for toys and beverages. Children love them!

Since harness limits their movements, cupholders act as their own storage space where they can sneak in a snack or two.

You can also look for adjustable armrests and headrests since they can significantly elevate the entire booster seat's comfort.


What is a 5-point harness booster seat?

A 5-point harness booster car seat is a specific child passenger safety restraint system with five attachment points to restrain your children at the hips and shoulders.

The harness will keep them stable and safe in the car seat. Thus, it will keep their crucial body parts supported.

In the case of an accident, the harness will transfer the crash forces to the rigid points of the kid's body into the seat.

So, your little ones will remain intact and fixed in the car seat.

Are 5 point harness booster seats safer?

A 5 point harness is designed to protect your child at shoulders and hips during the ride. 

In a car collision situation, the harness transfers the force to the mentioned restrained areas and back into the seat, reducing the risk of serious injuries.

A 5 point harness is also known for keeping the optimal position of the child throughout the ride.

So, in a nutshell, a 5 point harness booster car seat is a safer option than the belt positioned one.

What is the weight limit for a 5-point harness?

The weight and size mainly depend on the car seat models. Some may support more proportions, others less.

Typically, booster car seats have 5-point harness systems supporting and accommodating children between 65 and 90 pounds.

Once your children reach and overgrow that limit, they can continue using the car seat with the seat belt system of your vehicle.

best harness booster seat

How long should my child be in a 5 point harness?

Following the American Academy of Pediatrics instructions, kids should remain secured in a 5 point harness forward-face car seats/boosters until they reach the weight and height criteria given out by the car seat manufacturer.

As you can see, most booster seats with harnesses have the upper weight limit of 65 pounds, but this is not the case in all boosters.

This is why we always recommend you keep the manual handy in case you need to consult with it.

How to install a 5-point harness booster seat?

Follow the safety procedure below:

1. Check that the car seat matches the child's weight and height - the 5-point harness supports kids between 20 and 65-85 pounds and more than one year old. So, ensure the seat is correct for them. 

2. At 40 pounds and a booster seat, your kid should use the vehicle lap and shoulder belt. Some seats supporting 80-100 pounds might be used without harness straps.

3. Place the seat in the vehicle's back seat, in the central position, if possible. If not, place it behind the driver or passenger. 

4. Select only one method to install the car seat - check the manual 

5. Attach the car seat - read the manual to find the correct angles, and see how to use the seat belt or LATCH installation, and the vehicle's manual for the proper placement

6. Tighten the vehicle belt or lower anchors - LATCH - the set mustn't move more than 1 inch when you shake it

7. Buckle the child into the seat 

8. Apply the harness for kids between 20 and 40 pounds ( or between 65 and 85 pounds based on the model). They should be older than one year. Harness straps must be at or above their shoulders.

9. Ensure the harness straps are flat and snug on the child's shoulders.

10. Ensure the chest clip is sharply at the kid's armpit level.

11. The kid's back must be flat against the back of the seat.

Are 3-point harness car seats safe?

Yes, they are. The 3-point harness straps are designed to cover your children over the shoulders and between the legs.

The harness acts more like a seat belt than a traditional harness created for a racing-car style. Thus, it's best for children between 4 and 12 years rather than infants and toddlers.

Infants and toddlers use the 5-point harness with additional hip straps to help spread impacts and forces in the case of a car crash.

It's a crucial part of the harness, as it takes much force and spreads it across the children's torso.

What is the difference between a 3-point harness and a 5-point harness?

Both harness systems have the same purpose - to keep your child stable and secure while inside the car seat. However, there is a massive difference between the two systems.

Namely, both harness units contain leg and shoulder straps, covering crucial body parts and keeping your little ones fixed and optimal in the seats.

However, a 5-point harness system has additional hip straps to help spread and redirect the external pressure and impacts in the case of an accident.

This is essential in the forward-facing car seat mode, as the harness receives all the forces and pressure and then spreads it across the kids' torso.

Thus, it keeps them stable and unchanged for exclusive use.

What is the difference between a 4-point harness and a 5-point harness?

As their names suggest, the four and 5-point harness systems differ in design. Both serve to keep passengers safe and stable in the seats, yet the crucial difference is in the straps.

The 4-point harness provides 2 shoulder straps covering your shoulders and reaches the harness slots in your seats.

Then, it mounts in the harness slots. These straps mount and connect to the rear area of your motor vehicle. And its primary purpose is for off-highway use.

The 5-point harness, on the other hand, is a type of restraint that covers shoulders and legs, keeping passengers stable and secure in the seats.

However, the system offers additional hip straps covering the hips of the passengers and receives external force and impacts in the case of a car accident.

So, you can use it for your kids and for all travel types.

How many types of seat belts are there?

best harness booster seat for travel

There are multiple seat belt system types based on the type of the motor vehicle and its primary purpose.

However, the most prominent seat belt types include the following seat belt models:

- lap belts

- sash belts

- automatic seat belts

- three-point belts

- belt-in-seat - BIS systems

- five-point harness

- six-point harness

But, you can choose the best one for your needs according to the vehicle's purpose and type.

Are chest clip car seats illegal in the UK?

Yes, it is. According to the UK car seat laws, it's currently illegal to sell a car seat with a chest clip as a part of the car seat.

The main reason for this is that the official requirements claim that you must release a child from the car seat in one movement.

So, chest clip car seats are forbidden.

Are chest clips illegal in Australia?

According to the official Australian/New Zealand Standard AS/NZS 1754, the chest clips are forbidden both in Australia and New Zealand as a part of the children's restraint systems.

These are only allowed in the USA.

Why do Americans use chest clips?

A chest clip is a rugged plastic unit added to the USA car seats. Their primary purpose is to prevent the forward rotation of children in a car accident.

An American car seat uses the chest clip to keep the straps adequately placed on the shoulders.

In addition, if the chest clip is too low, the straps might be wider on the shoulders. On the other hand, if it's too high, it may be in the way of the children's throats.

When can a child use a harness booster seat?

According to numerous experts, it is best to place your kids between eight and twelve years old in the booster car seats.

However, it also depends on the weight and height of your little one.

Namely, sometimes your kids grow too fast; therefore, they need a harness booster faster than some other kids, or they still need a forward-facing harness car seat.

So, you need to follow the recommendations and labels, and if you're not sure, ask CPSTs.

What is the most comfortable booster seat?

With the ComfortTech that includes three separate layers of protection and pressure point relief, Evenflo Chase Harnessed Booster is our best pick for comfort in booster car seats.

  1. Question – I have two Britax “Grow with You” click tight booster seats for my kids, who are 9 and 11 years old.
    They have exceeded the height and weight limit for the 5 point harness, so they can now use the seat belt option instead.
    However, I feel that the 5 point harness is safer in case of accident because it keeps their hips and shoulders in place.
    Do you have any insight as to why the manufacturer recommends to switch to the seat belt option rather than continue to use the 5 point harness for bigger kids?
    Thank you in advance for your insights.
