Our Verdict
The Cybex Cloud G Lux is a compelling, high-end infant car seat with a unique recline feature that lets little ones get cozier outside of the car. This seat has a sleek look, a busy shell, and is extremely easy to install using the rigid LATCH connectors. We love the attention to detail and the side impact wings, anti-rebound bar, and load leg. The carrier is heavier than most, but it has more padding and potentially more support along the back area than competitors. The seat features a SensorSafe chest clip, non-rethread harness height adjustment, and softer fabric. Unfortunately, this seat didn't perform that well in our crash tests, resulting in a below-average analysis assessment. It is also very expensive. We think there are better options in our lineup that are either cheaper, have better crash test results, or both.
Our Analysis and Test Results
Cybex is a German company that merged with Goodbaby International Holdings Limited. They make car seats, strollers, baby carriers, furniture, and more.

Crash Testing
The Cloud's crash test results are lackluster. While every seat we tested is presumed safe and has passed the federal guidelines, we run a faster crash test with a more modern sled to identify those seats that are better than average.
The chest clip sensor recorded relatively low results for g-forces (lower is better). This performance is better than most competitors. If the HIC sensor had followed this pattern, it would have performed better in our analysis, but alas, it did not. The HIC sensor recorded one of the highest amounts of g-forces. Lower sensor results are desired as they indicate fewer impact forces on the dummies used during testing. The combined chest sensor and HIC results created a lower-than-average analysis result.
The Cloud has rigid LATCH connectors that are easy to use, but it somewhat depends on your car and how easy the LATCH anchors are to reach.

Ease of Installation LATCH
Thanks to a rigid LATCH system and connector guides, installing the Cloud using the LATCH system is one of the easiest in the group. If you're worried about installation, this one is almost foolproof.
The LATCH connectors slide out with a button push, and then you pull them out.
Pushing them onto the vehicle anchors causes a color change indicator to turn green, providing peace of mind that you've done it right. There is also an audible click. The base has a little more wiggle than some other options with rigid LATCH, but it definitely isn't going anywhere, and there is no worry about trying to get a strap tighter.
The Cybex Cloud load leg has a color change that indicates when it is installed correctly, but the whole thing felt wonky to us.

The Cloud also has an anti-rebound bar and a load leg. The leg extends from its storage place under the base. Ours seemed to be somewhat wonky as it didn't like staying connected to the base.
It extends with a button push, and when properly placed, a green collar appears at the bottom.
The Cloud's needle level indicator seems to get stuck occasionally and has a narrow window for proper leveling.

Recline Adjustment
The cloud base has four recline adjustment positions to help attain the right angle for installation. There is a needle-style level indicator on both sides of the base. Occasionally, we had to “wake up” the needle with a tap on the base to get it to move and settle.
The Cloud's base has an adjustable foot to help you find the right installation angle.

The recline adjustment lever is on the base above the lockoff.
The grey lever at the top of this image is the Cloud's recline adjustment, which raises or lowers the foot end to find the right installation angle.

It is an outstanding design compared to those that press against the vehicle seat, making them hard to use. This lever is super easy to use, and the foot moves smoothly.
Threading the vehicle belt through the openings and under the lockoff on the Cloud is easy.

Ease of Installation - Belt
Installing the Cloud using the vehicle belt instead of the LATCH connectors is almost as easy, and one of the easiest in the group to install this way.
The belt pathway has a large center lockoff that helps create the perfect amount of tension and locks the base onto the belt.
The pathway openings are large enough to use with bigger hands, and the lockoff didn't require too much pressure to push closed.
The Cloud's base provides images and written instructions to help you complete the installation process.

There is plenty of room to feed the belt, and the lockoff lid lifts and stays out of the way. It didn't take as much belt-tightening as competitors to get a stable installation, thanks to the straightforward lockoff.
The Cloud uses the American and European pathways. We prefer the European path that uses the shoulder belt across the back fo the carrier.

Ease of Installation - w/o the Base
Installation without the base is the hardest method for the Cloud.
While not prohibitively difficult, the carrier's heavier weight would still have us looking elsewhere if we planned to primarily install sans base.
The Cloud utilizes American and European methods, with European being preferred. The pathway is intuitive and has blue markers and color coding to help you. The clip on the back of the carrier helps keep the vehicle's shoulder belt from sliding.
Once installed, it passed the wiggle test, but its overall stability wasn't super inspiring. While it didn't twist or tip, it didn't feel as snug as we'd like. Depending on the test car, we had to use rolled towels (as outlined in the manual) to get a more secure fit.
The Cybex Cloud harness is easy to put on and has a non-rethead height adjustment.

Ease of Use
The Cloud has a little more going on than most infant car seats, but it still manages to be one of the easiest options to use.
The Cloud's buckle requires a deeper depression than most, but we love the idea behind the SensorSafe chest clip.
Credit: Matt Lighthart
Buckle
The buckle has nice padding on the back for comfort, but open access on the front. The button is easy to press but requires pressing deeper down than most. The prongs need to be manually removed. The chest clip is a SensorSafe clip, and it slides smoothly. The button doesn't require much force.
This SensorSafe clip pairs with a phone app and can give you alerts related to temperature, the clip's closed/open status, and whether it is still closed (presumably the baby is in the car) after you walk away from the vehicle. The goal is to decrease the odds of accidentally forgetting your baby in the car.
The release button and tighten strap on the Cloud are placed in the open and unhiden, but the plastic bevel could get really hot in the sun.

Harness Tightening/Loosening
Tightening and loosening the harness is straightforward with the typical pull strap and button release. The button and strap are located inside a plastic bezel, making them easy to access for parents, but the edge limits how much passengers can reach. We like the idea, but we worry that plastic could get prohibitively hot in a car on a hot summer day. We tested it in a car all day at 75 degrees in the sun, and while it wasn't a burning temperature, it was hot enough to make us worry about 100 degrees in the sun in Arizona.
Harness Adjustment
The Cloud has a lovely non-rethread harness height adjustment you can do with your baby in the seat. We love this thoughtful design because it helps ensure a properly fitted harness for every ride. There is a pull loop to move the section up or down. The crotch strap only has a single position.
The Cybex carrier feels somewhat wiggly when installed on the base.

Carrier to Base Connection
The carrier is heavy and shaped somewhat differently than most infant car seats, with an elongated profile. While not prohibitively difficult, it does make it somewhat more cumbersome to lift and place on the base.
The Cloud is about average for putting the carrier on the base, and in at least one test we only got one side connected correctly.
Credit: Matt Lighthart
We had some difficulty connecting both sides during testing with an empty carrier, but it was more predictable with a baby in the seat. We suggest parents give the handle a good tug to ensure the connection is secure on both sides.
The back of the Cloud carrier has buttons above and below the belt retention clip. One releases the carrier from the base, while the other reclines it when it is not in the car.
Credit: Matt Lighthart
Removing the carrier can be tricky at first, but we suspect you'd get it dialed in if this were your daily car seat. There are two buttons on the back of the carrier: one operates the recline feature while the other releases the carrier from the base. Once you get the right button, removal is swift by lifting the carrier up and away from the base.
The handle on the Cloud rotates smoothly using two release buttons simultaneously, and there is no canopy interruption.
Credit: Matt Lighthart
Handle
The Cloud handle has four positions, which is about average. If the handle is locked in place, any position is allowed when driving. At the rotation point, there is a button on each side of the handle, which you press simultaneously to rotate the handle. We had no difficulty moving the handle, and no issue with the handle and canopy colliding.
The Cloud has one of the best canopies in the bunch.
Credit: Matt Lighthart
Canopy
The canopy is giant compared to most of the competition and has a taut and finished look, lacking in most seats. It is easy to open and close, and it stays open without looking frumpy.
When not in use, the Cloud's rigid LATCH connectors fold back on themselves, swiftly tucking out of the way.

LATCH and Manual Storage
The LATCH connectors on the Cloud are rigid and flip around when not in use. It is effective and efficient. The manual is stored under the car seat at the rounded point, not on the base, which is good if you need it when traveling without the base.
The Cloud lifts off the base easily, but we kept pressing the recline button instead of the release button on the back.

Comfort/Quality
While the Cloud performed admirably for comfort and quality, it didn't wow us compared to some competitors.
The Cloud fabric is soft enough and somewhat stretchy, but does not look frumpy.
Credit: Matt Lighthart
Fabric and Padding
The Cloud has a premium look and feel, with more padding than the average seat and soft but durable fabric throughout. The fabric has a little bit of stretch and give, but looks good and retains its shape. The padding is relatively thick and plus, but it compresses a little more than others. The back has more padding than lower-end seats, potentially providing more support.
The crotch strap/buckle and shoulder straps all have soft padding, and they utilize snaps instead of Velcro to keep them on. There is a stitched pattern on the inside of the seating area near the baby's head on the right side that isn't likely to touch the baby or be uncomfortable, but it is a strange design choice.
The Cloud has plenty of space between the canopy and handle, and both move independently of each other with a sleek fit and finish.

Handle and Canopy
There is plenty of space between the handle and the canopy, and they move independently. Whether the canopy is open or closed, it is not affected by the position or movement of the handle.
The material is thinner than most and only filters light instead of fully blocking it, but it isn't so thin that you can see the baby through it. Given the bigger size and the downturned shape, it covers more of the baby and potentially blocks the sun at lower angles.
The handle is a thin, rounded oval shape that is smooth on all sides. It isn't as comfortable in your palm as you'd expect, and it could have benefited from a thicker design or grip pad.
The Cloud's shell is somewhat busy with extra parts and a hatch-like pattern that increase the potential of it collecting dirt and grime.
Credit: Matt Lighthart
Shell
The shell on the Cloud is busy with a lot going on. There are the usual stickers to contend with, but the design of the side impact wing and the multiple parts that allow it to recline create a more convoluted shape than we usually see. We suspect it will be hard to keep clean, and as gunk or sticky stuff accumulates, it could impact its ability to recline smoothly or retract the wings. It also scratches easily and has an odd ledge that allows liquids to be trapped and absorbed into the fabric and padding.
We weigh each car seat, like the Cynbex Cloud shown here.

Weight/Size
The Cloud's carrier weight is 12.3 lbs, making it one of the heaviest in the group without wheels.
This makes it a poor contender for those who hope to carry it frequently or use it on travel. The lighter options are closer to 8 lbs.
If you have a compatible Cybex stroller, we understand being drawn to the Cloud; otherwise, there are less expensive and better-performing seats available.

Should You Buy the Cybex Cloud G Lux?
The Cloud G is a lovely-looking seat with a unique recline feature for use outside of the car. We think it is easy to install using LATCH and the vehicle belt. It is easy to use and offers good comfort and quality. However, it is expensive, and the crash test analysis was below average. Given that there are cheaper seats that provide a potential additional margin of protection over this seat, it wouldn't be one we'd recommend to a friend. If you totally love Cybex and want to pair it with a Cybex stroller, we think you'll be pleased with it and the thoughtful features, but otherwise, we'd look elsewhere.
What Other Infant Car Seat Should You Consider?
For a similar price, you can get the highest-scoring seat with the most impressive crash test results we've seen thus far. The Nuna Pipa RX is easy to install using all methods, is high-quality, and is easy to use. If your budget is smaller, the Romer Juni has impressive crash test analysis results that can save you money and is easy to install. If you want something even less expensive without sacrificing crash test results, the Britax Willow S should make your shortlist.
