Cybex Cloud Q Car Seat Review

The Cybex Cloud Q car seat is $400 on Amazon

There has been much buzz about the new Cybex Cloud Q, a rear-facing-only seat that offers a recline option when not in the vehicle!  How does it measure up?

See below for our full Cybex Cloud Q car seat review
Last updated August, 2018

Installation With the Base

The installation with lower anchors on the Cloud Q base is virtually identical to the lower anchor installation on the Cybex Aton 2 and Cybex Aton Q. The recline foot has to be extended all the way to release the lower anchors from their storage; this can be a bit tricky to figure out.  Next, unfold the load leg and lower it to the floor.  The part of the base near the load leg should not be raised above the vehicle seat by the load leg.  The sequence that worked best for me was: unfold the load leg, place the base on the vehicle seat, use the lever to extend the load leg to the floor, then use the recline foot to ensure the correct level as shown in the level indicator. Otherwise, it can get very tricky to extend the load leg but not affect the recline of the seat.

It gets easier from here! The next step is to open the belt tensioning plate, then connect the lower anchors, using the lower anchor guides if necessary. Tighten the lower anchor strap, but don’t make it too tight or else the belt tensioning plate will not be able to close. You’ll soon find that there is a “sweet spot” where the latch strap is just loose enough that the belt tensioning plate will still close. Be sure to pull all of the slack to the adjuster side before tightening; there is a tendency for some of the slack to get caught on the other side. Close the belt tensioning plate to complete the installation.

Cybex does allow latch borrowing with this seat, vehicle permitting, but only up to a distance of 20 inches between the latch anchors.  This is a change for Cybex who in the past has allowed LATCH borrowing, vehicle permitting, for any distance.

Installing the base with the seatbelt proved to be much more difficult. The lap and shoulder belt together are routed through the blue belt guides, under the the belt tensioning plate. The belt guides have tabs under which the belt must be routed as well.  My own car, a 2016 Kia Soul, has an extra loop of fabric on the vehicle belt that made this almost impossible. Further, it takes quite a bit of effort to remove slack evenly along the belt. The manual suggests holding the lap and shoulder belts together and threading them through that way, but I needed an extra hand to use that method as the belt would bunch up.

After you remove the slack from the belt and tighten it, the next step is to close the belt tensioning plate and lock the seatbelt.  I expected this to be like the latch strap (and the previous Aton bases) where the base would be tight enough if the belt tensioning plate were closed after most of the slack was removed. However, because of the positioning of the blue belt guides, it’s necessary to tighten the belt virtually all the way and then close the belt tensioning plate. This is not an easy task!  After this is done, the seatbelt should be locked.

The recline foot is easy to use, though it must be used together with the load leg to achieve the correct result.  The level ball must be in the correct range for the baby’s weight.  The load leg must not change the angle of the seat, but the level ball is extremely sensitive and will move at the slightest pressure, including from that of the load leg.
The load leg may be used on a center floor hump as long as the load leg doesn’t change the angle of the base.  In my car, I could have used another “click” in between positions on the load leg, as I had trouble getting the load leg firmly on the floor while not changing the angle of the base.  Lowering the load leg before adjusting the recline foot seemed to help.

The Cloud Q may touch the seat in front of it as long as the vehicle permits it. Because the Cloud Q is very short front to back, this may not be an issue in most vehicles. We found the that the Cloud Q is narrow enough to install 3 car seats across the backseat of a vehicle in some cases.

Installation Without the Base

Installation without the base is done with the handle all the way towards the back of the vehicle. The vehicle belt is threaded through slots on the handle AND through slots in the carrier. If the belt is long enough, European belt routing is the preferred method.  Route the belt through both sets of slots and then after buckling, wrap the belt around the back of the seat and through the black clip. Lock the vehicle belt, and ensure that the red level line on the side of the carrier is level to the ground. If the belt is not long enough to use the European method, or if there is no shoulder belt, the American method is allowed as well, with the shoulder belt laying against the vehicle seat back.

Reclining When Installed: NOT ALLOWED

The manual states clearly that the car seat cannot be reclined while it is installed in the vehicle.  This is not possible to do when the seat is in the base, but it is possible when the seat is installed without the base.  Cybex has categorized this as misuse, which it certainly is, but we hope that the red tabs on the car seat will be enough of a deterrent.  Additionally, we’d prefer if the red tabs lock into place, since it’s possible to install Cloud Q without the base while the seat is reclined.  This is strictly prohibited by Cybex, and for good reason! Putting the car seat and the child in a position prohibited by the manufacturer could result in injury or death.

Linear Side Impact Protection (LSP) system

Like the other Cybex rear facing only seats, the Cloud Q features Linear Side Impact protection. It should be extended when the seat is installed in one of the outboard positions. The LSP that is towards the vehicle door should be extended. It should not be used in any other situation and should not be extended towards another car seat or person.  It extends when pulled out and retracts easily with a button.

Base Compatibility

The Cloud Q base has different shaped blue belt guides and a slightly different design than the previous Cybex bases. As such, it is not compatible with other Cybex seats.


Concerns Around Recline Feature

We encountered several challenges to using this seat correctly.

First, the infant insert.  The seat comes as shown, with the infant insert standing upright in front of the fabric flap (here, the flap is in beige). This places the straps at a height that is too high to accommodate most newborns.  The manual contains the sentence:

“The Cloud Q is shipped in the lowest position with the Infant Insert already in position.”

We have confirmed with Cybex that unfortunately, this is not the case.  The infant insert should be placed lower, behind the flap and against the crotch buckle as shown.  Cybex will be creating additional online resources this summer to help consumers with various aspects of using this seat, and the correct positioning of the infant insert will be included.

Second, upon recline, the crotch buckle and shoulder straps extend.  The reason for this is clear; if this did not happen, the car seat would not be able to recline!  However, this introduces a safety issue, in that a gap is created at the crotch.  The baby may wiggle down and/or pull his or her legs through the gap.  This would create a danger in that the child may be strangled by the chest clip.  We discussed this with Cybex, who would like to remind everyone not to leave the child unattended in the seat. It says this in the manual and on the seat as well.

We are afraid parents may regard this seat as a type of bassinet while it is reclined. What parent doesn’t try to accomplish something while their baby is napping?

Third, we found several issues with the straps. They tended to twist very easily, and on our seat and another we tested in a store, the straps got stuck and wouldn’t adjust after the seat had been reclined and then put upright.  Cybex has not heard this complaint from any other customers however.

Fourth, we experienced an issue where the tabs did not retract when the seat was put upright. Jostling the seat around a bit or taking out the child caused the tabs to retract. Cybex is working on a correction to this issue.
Last of all, at 13 lbs, this carrier is too heavy for many parents to carry around easily.


The seat has a small handle to use to engage the recline.  It looks easy enough, but it can actually be very difficult to get the hang of doing this; if you hold the handle of the seat with the other hand, that helps provide the leverage you need.

The red tabs that should prevent a baseless installation while the seat is reclined come out in the belt guides, but they do not lock in place when the seat is reclined. This makes it possible to thread the seatbelt through the belt guides and install it baseless while it’s reclined. Cybex is aware of this situation but feels the red tabs in the belt guide, and the language in the manual, are enough of a deterrent.  We join them in urging parents against installing this way as it’s not a safe installation.

Fit to child: Preemie

At 4 pounds and 17 inches long, our  “preemie” doll represents the average small preemie.  Due to the 8″ lowest harness height, this seat did not have an acceptable fit on our Preemie Doll, even with the infant insert positioned correctly. The straps were above the shoulders, which is not permitted.  Additionally, the flap in front of the infant insert doesn’t have slits for the straps, with the result that, as shown in the picture, the straps didn’t fit snugly around the preemie’s legs.

Fit to child: Newborn

Our newborn doll weighs 7 pounds and is 17 inches long.

When we reclined the seat, the infant insert rode up and did not fall back into position when the seat was put back upright.  

We reclined the seat a few times. After a few reclines, the infant insert had ridden up, and that created a crotch gap which meant that the baby could slip down so the straps were no longer below his shoulders.

Fit to child: toddler

Our 1 year old model weighs 16 pounds and is 29 inches long.

This doll fit in the seat with room to spare. There are two clicks left to raise the headrest.  It is a little snug around the shoulders though. Unfortunately, the seat is outgrown at 30″.  That is a shame for a seat with such a high shell height.

Where to Find

FAA Approval: The FAA approval label is found in two places: on the label on the side of the carrier and on the label on the underside of the carrier. The red sentence is clear and easy to read.

Manual Storage: The manual is stored on the underside of the carrier. This is convenient in that one would always have the manual even without the base, but it might be unwieldy to retrieve the manual if the child is in the seat.

Expiration: This seat and base have a six year expiration.  The expiration of the seat is clearly marked on the underside of the seat and within the manual itself, which is extremely helpful. The expiration of the base is clearly marked on the base.

Final Thoughts

We commend Cybex on offering a reclining seat.  Too often, parents leave children in car seats for too long, creating a dangerous breathing situation.  However, we feel that the Cloud Q has too many flaws for us to be able to recommend it. The dangerous crotch strap gap as well as the misleading instructions on the infant insert may lead to misuse, and the high carrier weight and twisty straps might make parents replace the seat early, a shame for a seat with such a high price tag.
