The Graco Tranzitions 3 in 1 harness booster seat is an ideal choice for you! Why?

Well, the car seat offers an extraordinary design from the very beginning. Thus you can use it for forward-facing children, and booster children, in both modes. Isn't that perfect?

But, what are other benefits? Hmm, read out Graco Tranzitions 3 in 1 reviews below.

Graco Tranzitions 3 in 1 Reviews: Should You Buy or Shouldn't You?

1. Overall design

Let's start from scratch.

I was astounded by the overall design when I first opened the package.

At first, the car seat seems bulky and robust, but it's not. I didn't need my husband to help me unpack it, as the car seat's weight measures only 12.5 pounds! Thus, the booster seat is one of the lightest car seats in the market, compared to other similar units.

Its proportions measure 19 (seat length) x 17.4 (seat width) x 26.5 inches (seat height), but the seat depth is also significant, measuring 10.5 inches. So, my child fully relaxes wherever we go out, and they have enough room for limitless moves.

However, if you're an active and always busy parent like me, you will need something like this booster! Why?

Well, as I have said previously, the Graco Tranzitions 3 in 1 booster car seat quickly and effortlessly transits into the forward-facing seat for your toddlers.

Of course, it's not an all-in-one car seat, so that you will need a separate rear-facing infant car seat, but it will operate great for toddlers and older children.

The booster car seat supports children 22-65 pounds in the forward-facing harness, and it keeps growing. Secondly, you can use it in the booster method in all three modes. Hence, you will find:

- highback booster mode: highback belt-positioning booster seat for kids 40-100 pounds

- backless booster seat for kids 40-100 pounds

- harness car seat with the 5-point harness system or forward-facing and booster kids

However, when you use the 3 in 1 harness booster seat in the belt-positioning booster or backless booster mode, make sure your child is strong and developed enough to wear the vehicle seat belts properly.

Remember: the shoulder belt must cover the shoulder and chest, and the lap belt must cross the upper thighs, not the stomachs.

And I like their dedication to safety features, so Graco has increased the minimum weight from 30 to 40 pounds.

2. Who is the Graco Tranzitions car seat intended for?

Well, I believe the primary focus is on active parents, as the car seat is extremely lightweight, portable, and convenient for car travel, so it will be quick to take it in and out of the car.

So, whether you set off an outdoor adventure or run errands, the Graco Tranzitions will be the right car seat for you. At least, it works well for my kids and me.

In addition, you will love its narrow design; as I said, it's not bulky or too complicated. So, you can place three across easily. However, you can also fold the two removable cup holders, and it will offer even more space for your little passengers.

But, for your confidence, ensure the vehicle seat fits the Graco Tranzitions car seat proportions, so when you add two more, there isn't a crowd and limit.

3. What about safety features?

Don't worry - I have covered all the crucial points.

Now, I'm a mother, and I always want the best protection for my children. So, I gladly choose the Graco Tranzitions car seat as my number #1 choice.

The harness booster car seat is a safe, secure, sturdy, and reliable car seat, specifically created for your peace of mind.

Firstly, the 3 in 1 harness booster car seat is strictly & rigorously crash-tested, so it meets & exceeds all FMVSS, NHTSA, and other safety rules and regulations.

In addition, the 3 in 1 highback booster, backless booster, and belt-positioning booster have also been side-impact tested for the safety of the 5-point harness system.

Now, the main point here is that the Graco Tranzitions seat doesn't have ESP and EPP foam lining for energy-absorbing benefits and complete side-impact protection. Instead, the 3 in 1 harness booster offers a blow-molded plastic design with energy-absorbing features, showing their maximum car collisions. Moreover, the same plastic design and quality are used for crumple zones and car bumpers for maximum security.

However, I always recommend numerous alternatives, such as Britax, Chicco, or even other Graco models with the side-impact protection you might use.

But, our 3 in 1 harness booster car seat also benefits from the safe adjust harness system. Namely, the 5-point is a no-rethread harness system, so you can change it for your kids as they grow. So, you don't have to install and reinstall it repeatedly.

In addition, the safe adjust harness system is additional support for your child, as the harness straps and, in general, harness covers their most vital body parts, so your kids cannot fall off or slip away from the seat while riding in the back.

In addition, you can find numerous testimonies on how the Tranzitions car seat saved their children's lives when their car flipped, including mine. That's why I'm fond of it.

4. Installation: Pass or fail?

Ugh...Overall, many parents reported and estimated the 3 in 1 harness booster as effortless and pretty simple to install and use. But, we still have others complaining about the right fit and secure installation process.

You already know that the harness booster benefits from the adjustable harness, ensuring headrest adjust and harness adjust benefits in one simple motion. So, the car seat will follow the excellent body posture of your children and make it more convenient for more prolonged use. Still...

We have parents with installation hiccups. So, let me tell you: the backless booster/high back booster mode/harness mode car seat contains both installation types: LATCH system, and vehicle seat belt installation.

But, you can encounter problems regarding both types if you don't follow the instruction manual.

Namely, regarding the LATCH system, the car seat includes lower anchors with hook attachment points instead of push-on attachments. Therefore, parents with deep-seat anchors in their vehicles will have struggles when attaching the lower anchor straps for a more secure and tighter snap.

And when using the seat in the harness mode, don't forget to attach the top tether correctly for more stability, even if you don't use the lower anchors anymore.

Regarding the seat belt installation, the Tranzitions seat and ease of setup process depends on the vehicle seats and seat belt systems. But, the seat belt path will show you the proper method and way to install it properly, but you may encounter struggles regarding:

- If you anchored all the critical points correctly

- If the vehicle's shoulder belt attaches to the front or side of the seat instead of the back side

I have tried both options, and I must admit, I was annoyed when things didn't go smoothly as I expected. But, after a few attempts, I managed to install it both ways.

You can choose only one option, so check what's more straightforward.

Also, I highly recommend the following procedure when it's hard to find the best solution:

- Watch videos on YouTube with Graco installation (you will see either parents or trained CPSTs)

- Stick to your instruction manual & follow the step-by-step procedure

- Read as many comments as possible on Amazon and Graco official websites to find similar problems and solutions

5. What about comfort benefits?

Of course, I wouldn't forget.

Unlike other booster seats, our Tranzitions seat is pretty straightforward to use. Thus, the Graco car seat is specific since it offers growing room and coziness for children to remain inside for an extended period.

The seat has a crotch strap on the base to make longer rides comfy. Also, the crotch strap is adjustable to two different positions for more convenience and security during the ride. Its measures are 6 and 7.5 inches, and you can moderate them as you like.

And due to the well-known 3 in 1 design, you can easily switch between the harness mode or seat belt mode, depending on the kid's needs.

However, the NHTSA & AAP recommend exact height and weight limits for car ages and stages. So, follow the rules and stick to the proper modes until your kids are ready for the next level of car seats.

Of course, with an adjustable harness, eight positions of the adjustable headrest, and a soft and supportive seat pad, your kid can wholly lean back and relax fully for the most enjoyable ride.

The harness covers the most critical body parts and offers more safety and comfort if the kids use the seat for an extended period. In addition, they won't be limited or pressured - the pads will provide more coziness and softness for trouble-free uses.

But, the dual cup holders make the best out of the seat.

Namely, the cup holders are the perfect solution for kids' snacks and drinks, and they will keep your little ones occupied when riding long distances. So, they'll remain happy in the vehicle's back, and you can focus on the road better. At least that's my case.

And, the seat fits almost all SUVs, cars, or minivans.

6. Maintenance

All parents like keeping their car seats clean and fresh for more robust uses. I like that as well, and if I could, I would clean my car seats every five minutes! But, unfortunately, I cannot help it; I'm a perfectionist, sorry.

So, you'll be thrilled to know that the car seat offers the quickest and most uncomplicated cleaning and maintenance. As you will see, the car seat has a removable, machine-washable seat pad, so you can clean it effortlessly and make it fresh for subsequent use.

But, the seat also includes a machine-washable fabric of the seat cover for instant maintenance. In addition, the machine-washable seat pad and cover are dry-safe, so you can instantly clean and place them back for more fragrance and scent.

But, if you have messy kids as I do, the seat will be user-friendly as you can remove dual cup holders as well and clean them with water and soap.

Finally, you can wipe them clean and place them back into their place. So, the cup holders will be valuable and practical for longer rides with kids.

7. A room for improvement? Hell YES!

Don't get me wrong - this is an excellent car seat; it's just that it can be better.

Many complain that armrests are too short, especially if they have bigger children.

In addition, numerous parents complain about its cheap and straightforward design. But, the seat isn't really what you pay for. It has innumerable benefits, and you need to rely more on them.

But, of course, you're always free to switch to alternative options if you're not satisfied with what you can get.

8. What are the alternatives?

a. Graco Atlas 65

One alternative is the Graco Atlas 65 2 in 1 Harness Booster Seat.

The seat is also ideal, as it offers a 5-point harness safety system, easy transition from a forward-facing to a booster method, and an adjustable harness for growing children. Also, both booster seats have an easy one-hand motion for adjusting the headrest and harness.

Finally, they have similar height and weight limits, the same working modes: rear-facing not included, and similar comfort features.

However, the two seats differ in the following points:

  • The Atlas model is heavier and bulkier compared to Tranzitions
  • Atlas has two seating modes, whereas Tranzitions has three

Thus, the Tranzitions model might be more advanced.

b. Graco Nautilus 65 LX

Another alternative is the GRACO Nautilus 65 LX 3 in 1 Harness Booster Car Seat.

The Nautilus model is considered more advanced, the next generation of the Tranzitions.

Both models have the same design, adjusting modes, two types of installation, and adjustable headrests and harnesses. However, there are some differences:

  • Nautilus has one cup holder instead of two
  • Nautilus is heavier and bulkier than our model
  • Nautilus is more expensive
  • Tranzitions lack reclining options, and the former has three
  • Tranzitions lacks side-impact protection, and Nautilus has energy-absorbing foam and steel-reinforced frame

c. Graco Tranzitions SnugLock

Yet another alternative might be the Graco Tranzitions SnugLock 3 in 1 Harness Booster Seat.

The seat is actually the same seat as the original model, just slightly advanced. Both models are similar in design, but the SnugLock model is an upgraded version of our original travel-friendly car seat.

Both versions are lightweight, durable, and sturdy enough for all travel types. In addition, both are FAA-approved and user-friendly.

But, the main difference is that:

  • SnugLock is more costly
  • SnugLock offers nine harness and headrest positions, whereas the original model has only eight
  • SnugLock has wider armrests
  • Both installation types are more effortless and improved than with the first model

But, overall, it offers the same functions as the previous version we have reviewed so far.


Is Graco Tranzitions a good car seat?

Yes, it is. Overall, the model is an excellent seat for long distances and all travel types.

You can install it for more stability either with the seat belt or LATCH, and it will show excellent resistance in car accidents.

Even if its frame cracks, your child remains intact. It's also easily adjustable and convertible to different modes.

Is the Graco Tranzitions 3-in-1 FAA approved?

Yes, it is, but only if you use it in the harness mode. Otherwise, you cannot use it for aircraft, as the booster seats, in general, are forbidden for the aircraft.

But, the seat weight meets the rules and regulations, and if you use it as a harness seat, you can travel by plane.

Does Graco Tranzitions have a LATCH?

Yes, it has the LATCH system for installation, although it might be hard for you to install it for the first time. But, you have to follow the attachment point and find the hooks instead of the button for the proper attachment.

How do you loosen the straps on Graco Tranzitions?

You can loosen them by pulling the shoulder and stomach straps. Next off, the straps will loosen, and you can place your finger on the straps.

Check the tightness with the pinch tests - if it's too loose, tighten them for more stability.

You conduct it by pinching the strap and ensuring there's no slack between your fingers and everything is snug and tight. Otherwise, your kid can fall off.

What age is Graco Tranzitions for?

It's made for kids between 3 or 4, to 8 to 12 years old.

Does Graco Tranzitions fit 3 across?

Yes, due to its narrow design. And, you can remove cup holders for even more space.

What is a 3-in-1 booster car seat?

It's a seat that switches from a forward-facing harness to the belt-positioning or backless booster seat, following your kid's growth and development.

Graco Tranzitions 3 in 1 Reviews: The Final Thoughts

If you don't want to spend much money on rear-facing seats, forward-facing car seats, and booster car seats, make sure you purchase the Graco Tranzitions 3 in 1 harness booster seat.

The car seat will be the option for long car rides, with convertible car seat mode, harness booster mode, belt-positioning booster mode, and the backless booster mode, depending on your kid's needs.

So, why don't you put your mind at ease & enjoy the comfiest rides with the 3 in 1 safe car seat usage? Don't miss it!
