Graco Affix Youth Booster Seat

Graco Affix Youth Booster Seat vs Highback Turbobooster Car Seat

The Graco Affix Booster Seat is an Amazon bestseller that you really can’t go wrong with. It’s a great seat with some great features, and it’s been tried and tested by parents across the world.

There are plenty of neat features that come with the seat. For example, you can switch it to a backless seat, which helps to prolong the longevity of its lifespan. The headrest is also fully adjustable and designed to give maximum comfort to your child while on the move. This is incredibly important, especially on long car journeys.

Graco says that this seat has undergone extensive crash and impact testing to provide buyers with as much peace of mind as possible when transporting their little ones. The seat also contains EPS energy-absorbing foam liner for added comfort.

The Affix car seat can be used for children from 30 to 100 pounds (or 38-57”), meaning they are adequately comfortable during the first car rides of their toddler lives. After this, you can convert the seat to the backless system when they grow bigger and continue to use the car seat as your child grows (which, as you know, is often scarily quick!).

This seat also features what Graco call ‘Safety Surround Side Impact’ technology, which has been developed to protect and support your child’s head and body. However, perhaps the most important benefit of Affix is the latch system. This means your seat can be securely locked into place and will not budge, even when on the move.

Not all car seats offer this and it’s a surefire way to ensure your child’s seat isn’t going anywhere. This is a massive plus point.

There are loads of reviews on Amazon for the Affix and it currently has a rating of 4.6 out of 5 stars. In fact, 74% of all reviews are 5-star rated, which shows it’s well-loved by parents from all walks of life. However, we’ve gathered some of the best reviews so you can get a better understanding of what real moms and dads think.

  • Many parents love that it’s so easy to assemble and found the latch system very easy to use.
  • It’s been reported that this car seat is very comfortable and keeps their child upright when traveling.
  • A few parents did mention that at first, they had difficulty locating the cup holder until they played around a little bit with the car seat.
  • One parent had a very unfortunate accident in their car, but thanks to the Affix car seat her son “emerged without a scratch”.

Graco Highback Turbobooster Car Seat

Graco Highback Turbobooster Car Seat

The Graco Turbobooster is a very reliable seat with backing from the Insurance Institute for Highway Safety. That’s always a good thing to bear in mind when making a purchase. It’s been awarded ‘Best Bet Booster by the institute as it’s such a reliable, comfortable baby seat.

This helps to provide parents or guardians with peace of mind as we’re well aware that putting your trust into a product for your baby can sometimes feel a bit scary.

When it comes to listing features, the seat contains almost everything that the Affix boasts (including backless capability), with the exception of the latch security system. However, one feature which the Turbobooster has over the Affix car seat is the storage.

On the Turbobooster there are cup holders which are completely hideable underneath the seat. This means when they are not in use they can be conveniently tucked away out of sight. In comparison, the cup holder on the Affix can’t be hidden away.

The only real downside, when compared to the Affix car seat, is the fact that it has no latch system. This means the seat is never truly connected to the actual car seat and allows for a little wiggle room.


  • Suitable from 4-12 years of age.
  • Adjustable headrest.
  • Features cup holders that hide away.
  • Built-in storage.
  • Extra padding for added comfort.
  • Machine washable fabrics.
  • Meets Graco’s safety standards.
  • Side impact protection in both seat and headrest.


  • It’s ever-so-slightly cheaper than the Affix.
  • It won the ‘Best Bet Booster’ Award from the Insurance Institute of Highway Safety.
  • It features hideable cup holders.
  • It’s lightweight, so it’s easy to move from car to car.
  • It’s super comfortable.
  • It’s been extensively crash tested to meet or exceed US safety standards.


  • No latch system to strap the seat directly to the actual car seat.
  • It’s not the best choice with cars that feature a forward-leaning headrest.

Parents’ Opinion

Like the Affix, the Turbobooster has plenty of reviews on Amazon – again with an average rating of 4.6 out of 5. 72% of reviews are 5-star rated, so it almost perfectly matches the Affix if you compare the two side by side with their reviews. To make life a bit easier, here is what some parents are saying:

  • One parent raved that their “four year old thinks its very comfortable and loves the dual cup holders and armrests”.
  • Another parent liked that their children could sleep comfortably and upright, while their backs and necks remained supported.
  • The armrests are well-liked, as is the fact you can use it without the backrest.
  • A few people struggled with the weight limit.

The Verdict

In our opinion, both seats provide adequate support and safety for your child, but the Affix seat gives you extra peace of mind knowing the seat is locked firmly in place during a journey. This means the Graco Affix Youth Booster Seat is our top choice this time.

We think it’s worth spending the extra ten dollars for the added security for your little one. We also prefer the look of the Affix seat – it looks a little more upmarket and modern than the Turbobooster, particularly in the black and red finish.


Question: What do they both come as with as standard?

Answer: Both have the removable back option to allow for growing children and eliminate the demand to purchase new car seats frequently. They also both come with storage such as cup holders and a tray sizeable enough for devices such as toys and handheld gaming devices, etc.

Question: How do I clean the fabric on both car seats?

Answer: The fabrics on the Graco Affix Youth Booster Seat and Turbobooster are removable and machine washable. Metal and plastic parts may be cleaned with water and mild soap.

Question: How do I attach the back of the Highback Turbobooster to the base?

Answer: You’ll find ‘U’ shaped hooks on the bottom of the backrest will interlock with bars on base. When you’re attaching the backrest to the base, make sure no part of the seats covering interferes. Them, push the backrest up once it’s securely attached to the base. Your car seat is now ready.

Question: What is EPS foam?

Answer: In a nutshell, it’s a type of foam that’s mainly used on car interiors and special seats that are designed to protect the person sat in it from impact. EPS foam gives great protection and adds a huge safety element to the car seat, which is what makes Graco a trusted brand.
