Cybex Solution Q-Fix Review

The Solution Q-Fix is one of Cybex’s high back booster offerings.  The Q-Fix has been on the market for some time now;  offering both comfort and ease of use features.  Today, we’ll take a close look at this booster.

Cybex unboxing.

Straight out of the box, the Q-Fix comes in two main separate pieces, the lower portion and the upper portion.  While it does come separate, it is important to note that the Q-Fix should not be used without the upper portion attached.  It is a high back booster only. There is a tag on the seat to indicate that it should not be used without the back and another warning label on the seat itself. The assembly of the top and bottom portions of the seat is very straight forward.  Line the pieces up and move the top portion up so that they snap into place.  Once together it’s a very solid seat that is not prone to the back falling off.  While the back falling off while carrying is not a safety concern, some parents find that it’s annoying and prefer to use a seat that stays intact during movement.



Cybex Q-Fix Headrest Warning label



Cybex_LSPWhen the seat arrives, the linear side impact protection bolsters are not attached to the seat either.  These need to be attached to the torso wings of the seat during assembly.Cybex_LSPAttach

The linear side impact protection bolsters have three posts which connect them to the torso wings  To connect them to the torso wings, line them up with the holes on the torso wings and slide down to attach.









Manual Storage

Manual Storage


The manual is shipped loose within the packaging. There is a pocket on the back of the seat that can be used to store the manual when it’s not in use.  We always suggest keeping the manual with the seat so that it’s readily accessible should questions arise at any time.









The rigid lower anchor connectors that come with this seat are a little bit different from most anchors we see in use today.  I’d never seen anything quite like them before!

Cybex_LACollageInstead of being separate pieces, they are on a bar that rotates towards the seat when they’re not being used.  The rigid lower anchor connectors rotate towards the back of the seat when they’re in use.  Since they are fixed on the bar, it makes attaching the rigid lower anchors slightly more cumbersome than more typical lower anchors.

The bar is free moving as well, so they have to be lined just right in order to attach them to the lower anchors.  Once they are attached to the lower anchors, grab the lower anchor adjustment handle, and push the seat into the seat back. You’ll know the seat is in correctly when the indicator on the lower anchor connectors are in the green.

Good to go!

Cybex has a very specific set of rules about how the booster must sit on the vehicle seat.

The vehicle head restraint must not interfere with the booster, the booster seat must not overhang the vehicle seat, and the backrest of booster must rest against the vehicle seat.

These rules can account for an excellent fit when all of the conditions are met but it could make fitting the Q-Fix a challenge in vehicles that have fixed head restraints, seats with small footprints, or overly contoured vehicle seats.

One of the unique features of the Cybex booster is the reclining headrest.  There are three positions on the headrest that can easily be moved by the child to adjust the headrest to minimize head slump.



The belt guide on the Cybex is  unique as well. Once the seat belt is threaded into the belt guide, another red piece keeps it in place.


With my vehicle and set up this was fantastic because it made it hard for the belt to come out of the guide.  The belt guide is also fairly open, meaning the belt didn’t get caught in the belt guide and not retract correctly.  That’s always a plus!








Fit to Child

Two finger width measurement.

The Q-Fix requires that the headrest be positioned two finger widths above the child’s shoulder.  This makes it seem like it needs to be higher, but is the correct position for the shoulder belt for this seat.











Cybex Q-Fix fit: 7 year old model


Now that both of my daughters are of booster age, I was able to get two opinions of the seat and see how two totally differently sized children fit in the seat.

Both of my girls initially thought the seat was squishy and comfortable.  Bonus points from the little one because of the bold color!  I first used the seat with my oldest daughter, who is 7 years old, stands 50 inches  tall, and weighs 49lbs.

The belt fit on her was optimal and she enjoyed the automatic adjustment of the torso wings. As the headrest is raised, the torso wings adjust outward to provide a comfortable fit.  She was not too terribly impressed with the reclining headrest.  As a seasoned booster rider, she knows how to properly sit and how to stay upright while sleeping so this wasn’t as important for her.

Staying upright while sleeping and sitting properly are two of most important factors to consider when deciding when to put a child in a booster vs. a 5pt harness.  You can read more about when to make the transition in our article here.



Cybex Q-Fix Fit: 5 Year Old Model

My other daughter is 5 years old, 44 inches tall, and 46lbs.  She is brand new to the booster world and was very excited to show me how she could sit still and buckle the seat all by herself.

The Q-Fix provided an excellent belt fit for her.  She was more pleased with the reclining headrest than her sister was.  She said it reminded her of her pillow in bed.  This would be a great feature for kids who are just learning to use a booster.








Cybex Q-Fix Leg Overhang

Cybex Q-Fix Leg Overhang


The one complaint that both of these models had was that they said they felt like they were sliding forward.  The depth of the seat is 13.5 inches, which is rather shallow.  Both my girls’ knees bent far beyond the edge of the seat, which caused the feeling of sliding forward. While this was a downside for my vehicle and children, the depth of this seat would be beneficial for those with vehicle seats that are small front to back.  Remember, Cybex does not allow the seat to overhang the vehicle seat.





Overall Impressions

Q-FixThe Q-Fix cover is nice and plush, and the seat comes in a variety of colors.  The range of bold colors can be appealing to a child.  The Q-Fix would not be a good seat if you are trying to fit three seats across in a row.  While the base is quite narrow, the torso wings make it a quite bulky.  The armrests also do not fit well underneath other seats.

Overall, the Cybex Q-Fix provide an excellent belt fit for a booster.  Because of the relatively shallow seat pan, the Q-Fix might be better suited for a child with shorter legs.  The Q-Fix would be a good booster to use with a child who is booster training because of the reclining headrest feature.

Cybex did not provide a seat for this review and as always, opinions are that of the author.
