Graco car seat booster: Best Child Safety Booster Car Seats

  • by

Current booster ratings

IIHS ratings take the guesswork out of selecting boosters most likely to provide good lap and shoulder belt fit in a range of vehicles. Unlike child restraints with built-in harnesses, booster seats rely on vehicle safety belts to restrain children. Boosters are supposed to make adult belts fit children better and are for kids who have outgrown their forward-facing restraints.

Consumers can check the National Highway Traffic Safety Administration’s website for recalls on boosters and other child seats.

Manufacturers with top-rated boosters can use this logo in their advertising.

The Institute puts the booster seats it tests into four categories:

  • BEST BETs are seats that provide good belt fit for typical 4 to 8 year-olds in almost any car, minivan or SUV.
  • GOOD BETs provide acceptable belt fit in most cars, minivans or SUVs.
  • Not Recommended don’t provide good belt fit and should be avoided. There are currently no boosters on the market with this designation.
  • Check Fit applies to booster seats the Institute has tested that have varied results depending on child size and vehicle model.

Proper fit is key

Our ratings identify boosters most likely to provide good lap and shoulder belt fit. Safety belts are designed with adults in mind, not kids, but when a booster seat is doing its job, the vehicle belt will fit a child correctly. That means the lap belt will lie flat across a child’s upper thighs, not across the soft abdomen, and the shoulder belt will cross snugly over the middle of a child’s shoulder.

Checking booster fit

Both the lap and shoulder belts must fit your child correctly.

Lap belt fit — The lap belt should lie flat and on top of the thighs, not higher up on the abdomen.

Good lap belt fit:
outline = arm rest removed to show belt positionPoor lap belt fit:
outline = arm rest removed to show belt position

Shoulder belt fit — The shoulder belt should fit snugly across the middle of the child’s shoulder. If it falls off the shoulder or rests on your child’s neck, it won’t work as well. An improper fit could encourage your child to move the belt to a dangerous position, such as behind the back or under the arm.

Test protocol

IIHS assesses boosters using a special dummy representing an average-size 6 year-old. Engineers measure how three-point lap and shoulder belts fit the dummy in each of the tested boosters under four conditions that span the range of safety belt configurations in vehicle models. An overall rating for each booster is then assigned based on the range of scores for the lap and shoulder belt measurements.

Graco TurboBooster Review – Updated Model

(Last Updated On: December 2, 2021)

Graco TurboBooster

The Graco TurboBooster has been a solid, well-fitting, popular booster seat for many years for good reason!  It is lightweight, very simple to assemble and use, and fits a wide variety of children well.  It’s also budget friendly, making it a good choice for many families.  The TurboBooster we know and love has seen a few small but important updates so we’ll take a look at this old friend with fresh eyes.

Carpooling Essentials

  • Easy to set up without (very much or any) adult assistance
  • Easy to carry
  • Consistent belt fit


The TurboBooster comes out of the box in five pieces: two armrests, a bottom, and two back pieces. The manual, registration card, screws for the armrests and the shoulder belt positioning guide for backless mode come in a plastic bag.

Do NOT throw away the screws!

Don’t throw away any of it, actually – it’s all very important!  Be sure to fill out the registration card  or register your seat online right away.

Graco TurboBooster assembly

The manual has clear assembly instructions.  Here’s an overview:

First, put the lower back support and the headrest pieces together, then attach the soft goods.

Graco TurboBooster screws in the armrests

Next, attach the two armrests to the bottom part of the booster, and install the screws that came in the package with the manual.

The TurboBooster will not perform as intended in a crash without the screws – don’t forget them!

Graco TurboBooster assembly

To attach the high back portion of the booster to the bottom, line up the U shaped hooks on the bottom of the backrest with the bars on the base.  Make sure that none of the soft goods are in the way, and lift the backrest up.  It will click into place, then the booster is ready to be used!

Improved Base to Back Connection

The new connectors are a great design improvement – the backrest and bottom portions of the older versions of this seat notoriously fell apart if you tried to move it from car to car. This new version, however, is pretty darn secure, and can be moved with ease.

The final assembly step is to route the shoulder portion of the vehicle seat belt through the shoulder belt guide, then make sure that the lap belt is under the armrests.

Headrest Adjustment

Graco TurboBooster headrest adjustment

To adjust the height of the headrest and belt guide, squeeze the red handle at the top of the seat, then pull up.  Do this as the child grows to ensure that the red belt positioning guides are slightly above the child’s shoulders.

Vehicle Headrest

Graco TurboBooster gap between booster and vehicle seat

When using the TurboBooster in high back mode, it does not require a vehicle head rest behind it. The manual specifically states that the vehicle headrest should not create a gap between the vehicle seat and the booster seat. If the head restraint pushes the headrest forward, adjust or remove it so the seat will sit flush against the seat back.

Check your vehicle manual to make sure that removing the head rest is allowed — if the head rest is creating a gap and cannot be removed from the vehicle, you’ll need to try a different seating position. Remember, though, that in backless mode, the child must have head support to the tops of their ears.


Graco TurboBooster does not permit overhang

The manual prohibits the booster from extending off of the vehicle seat in any way.  This restriction could make the TurboBooster incompatible in some shallow seating positions. Be sure to check how the booster fits on the vehicle seat when choosing where to use it in your car.

Fit to Child

High Back Mode

5 Years Old

Graco TurboBooster 5 years old

This model is 5 years old and at the top of the charts for both height and weight.  He’s 47 inches tall and a solid 84 pounds.  He is new to non-harnessed car seats, but is booster training in his dad’s truck on short drives around town. Believe it or not, he still fits within the weight and height limits of his Britax Frontier in his mom’s car!

When using the TurboBooster in high back mode, the shoulder belt crosses his collarbone, but is a little high on his neck. The lap belt is nice and low on his hips, touching his thighs.

The first few times he tried to climb into the TurboBooster, the seat moved around on him a bit, and he had to get out and start over.  After a few tries, though, he figured out how to climb in without moving the booster seat out of position.

He does not have much hip room to spare in this seat, but he claims it’s “comfy” regardless.  He is able to sit all the way back, and properly route both the lap and shoulder belt portions under the armrests. When he tries to buckle the seat belt, he has to rotate around and lean over fairly far to connect the belt pieces, but he’s learning quickly how to remove the extra slack this creates and to ensure that the shoulder belt remains in the belt guide.

More About Our Model

A wider booster would likely be more comfortable for this model, but he has no complaints about this seat.  The headwings and high back are a good reminder for him to sit up straight,  though I doubt he has room to slump because he has broad shoulders and behind. He particularly likes the cupholders, and the fact that they slide in and out. Perfect for hiding treasures!

Since he is at the top of the charts for height and off the charts for weight, this seat will not last him as long as most other children. But if your little is of average height and weight, this is a great seat that will fit them well.

Note About the Shoulder Belt Guide

The vehicle seat belt does slip out of the shoulder belt guide rather easily in the course of regular use.   It is very easy to slide the belt right back in, but make sure that someone checks every time the child buckles in that the shoulder belt is still in the guide.

6 Years Old

Graco TurboBooster: 6 years old

This model is 6 years old.  He weighs 42 pounds and is 42 inches tall.  The TurboBooster fit him well, he was able to buckle himself in without any issues, and he found the seat comfortable.  It’s this kind of consistent belt fit that makes us such big fans of the TurboBooster!

We removed the padding insert in the headrest with this model.  The TurboBooster fit him better without that insert.

8 Years Old

Graco TurboBooster 8 years old

This kiddo is 8 years old.  She weighs 45 pounds and is 46 inches tall.   The TurboBooster fits her well.  She finds it very comfortable and she likes the slide out cupholders.

7 Years Old

Backless Mode

Graco TurboBooster 7 years old

This model is 7 years old, weighs 100 pounds, and is 54.5 inches tall.  She is right at the weight limit for the TurboBooster, and close to the height limit of the high back booster portion of the seat.  Even though she is within the stated limits of the seat, she has already outgrown it in high back mode. The headrest is too low, making the vehicle seat belt curve below her shoulder.

When we took the back off the seat, she got a much better fit in the TurboBooster.  She doesn’t have a lot of room to maneuver the seat belt, but she’s a booster pro and was able to buckle herself in with no issues.  The shoulder belt fit was great, so we didn’t have to use the seat belt positioner that comes with the seat.  This is the same booster she uses in her mom’s car, so she was an old pro.

7.5 Years Old

Graco TurboBooster: 7. 5 years old

This model is 7.5 years old, weighs 63 pounds, and is 50 inches tall.  She’s got plenty of room to grow and enjoys the novelty of the occasional backless booster ride.  The TurboBooster is easy enough for her to carry around and set up in the vehicle so it would be a great carpool option for her!

Important Information: Where to Find

FAA Approval

Graco TurboBooster FAA label

The TurboBooster requires a lap and shoulder belt, so it (like all boosters) is not FAA approved. However, the backless portion of the seat is light and compact enough that it could easily be carried on board the plane and stored in the overhead bin. Then you will be sure to have it at your destination.

The label prohibiting use on aircraft is on the bottom of the backless portion of the seat.

Manual Storage

There is a handy spot on the bottom of the backless booster portion of the seat to store the manual.


Graco TurboBooster manual storage and date of manufacture

This TurboBooster has a 10 year expiration. You can find this information in the manual, and also stamped on the bottom of the seat.  The date of manufacture label is on the bottom of the backless portion of the seat, too, and will show when the seat was manufactured.


  • Budget friendly
  • Does not require vehicle head support
  • Converts to backless mode
  • Has cup holders
  • Easy to use
  • U-shaped hooks on bottom of the backrest that securely connect the back to the base


  • Narrow seating area
  • Requires assembly, specifically screws in the armrests
  • Booster cannot hang over the edge of the vehicle seat
  • No lower anchors

Overall Thoughts

I have very few complaints about the TurboBooster. It provides a good belt fit for both the shoulder belt and lap belt for most booster-ready children. It is easy to put together and use, it is reasonably priced, and, according to my model,  relatively comfortable.  It is lightweight, making it a good choice for travel, and easy to move between cars.  The cupholders are a nice bonus, but make sure no perishables get tucked away in there – that could be gross!  All in all, this updated version of the seat takes everything we liked about the earlier version and makes it better.

Great car seat for toddlers and older. I like that it’s thin. We have a small car and with another baby on the road, I needed something less bulky than my other Graco car seat. This one is super thin. Very well made and easy to install. I love that my little one can grow into it and it has different settings for every age of her car seat travel. Definitely recommend! It is very beautiful and graceful. The lid is also easy to remove and wash. The price is pretty…

Bought this car seat for my 5 year old daughter – we used Nuna Rava on her, which we love, but we are ready to sit on the booster to change dishes. Installing this chair is an absolute breeze. I have two big problems with this seat: 1. It makes the loudest beep when your child is in it – there is foam on the sides of the seats and every time your child is in the seat or you drive on a bumpy road, the car seat makes unbearable sounds from the friction of the foam . ..

I bought this seat for my 7 year old daughter who is 46 inches tall and weighs about 43 pounds. It has evolved from a forward-facing seat belt system and now uses the high-back reinforcement feature. She likes it because the car seat belt is more comfortable. and less annoying to use. She is very annoyed by the straps that wrap around her legs and groin area. As expected from Graco, the car seat comes with good documentation and instructions for…

The car seat has a minimum weight of 22 pounds and is forward facing only, so it is not suitable for children under 1 year old. The rear-facing seat provides more support and security, so ideally this Graco car seat should not be used until the rear-facing seat has exhausted its capacity. It’s also a great “grow with me” seat that offers seat belts, then a high-back reinforcement for proper seat belt position…

I needed another car seat for my eldest daughter who will soon outgrow car seats too, so we bought this Graco baby seat that works if we need to repair it. My family has been using Chicco car seats for 7 years now and they love the quality so this Graco can be compared to our experience with Chicco. The Graco car seat looks good with plenty of padding and is much lighter than our Chicco car seats which is great when you need to move…

The chair has a lightweight yet durable construction. The deep headrest provides good head protection, the sidewalls cover the child’s shoulders in a side impact.


The car seat has a number of convenient adjustments that allow you to adapt the seat to the age and height of the child.

The headrest is adjustable in height to ensure that the child fits properly in the seat as they grow.

To raise the head restraint, use the gray button located at the back, in the upper part.

There are 7 height adjustment positions for the head restraint.

A special anatomic insert is provided for babies. A small child is tightly fixed in the chair, which ensures greater safety.

Up to the age of four, the child is secured in the car seat with a five-point safety harness.

The shoulder straps are equipped with wide and soft pads made of thick non-slip fabric.

There are plastic holders on the sides so that the belts do not interfere when the child is seated.

Before placing the child in the seat, you need to unfasten the lock by pressing the red button in its center. Next, stretch the straps to their full length. The belts are pulled out by pressing a button in the slot in the lower central part of the seat. After landing, the belts are reduced to one point and fixed in the lock. The lock is framed by a soft lining that protects the child’s groin from injury.

Graco Endure Child Restraint

The harness system tightens with a strap located under the button.


At the age of 3-4 years (height above 95 cm), the child is fixed with a regular car belt. The chair transforms into a group 2-3.

The five-point harness and buckle are attached to the chair base using metal holders. When transformed into a group 2-3, they are completely removed.

Group 2-3 (15-36 kg)

The child and seat are held in place by the vehicle’s standard three-point seat belt. The belt passes through special guides.

Before the child sits in the seat, the diagonal strap must first be guided into one of the red plastic guides under the headrest. They are located on both sides and are used depending on where the child seat will be installed in the car. The guides are located very conveniently, so the belt is carried out easily.

After the child is seated in the seat, you need to connect the two straps of the car belt under the armrest, pull it up to the lock and click it into place. It is important that the belts are not twisted and well tensioned.

Material quality

The fabric is soft, pleasant to the touch, does not irritate the skin.

Car seat cover can be easily removed and machine washed at 30 degrees (delicate wash).

Car seat frame made of high impact plastic.


Instructions in Russian included.

The instructions are located on the side, in the inner pocket of the upholstery.

There are pictograms with installation information on the side of the chair body. Mounting schemes are as simple and clear as possible.
