BubbleBum Review
The perfect choice for travel and carpooling, but its lower quality and crash test result make it less ideal for everyday use
Credit: Abriah Wofford
The Skinny
The BubbleBum is one of our travel favorite booster seats. It is an inflatable cushion that boosts children up so the vehicle seatbelt properly aligns with their body for safe fitting. This favorite car seat is small and very lightweight, making it ideal for carpooling and traveling or for instances where children need to carry it themselves. While this product has some inherent issues, like the use of lower quality materials and some difficulty with seat belt retainers, we still think it is the best thing going for times when you may need to carry or transport a booster seat for safer driving. This option is not the best for everyday use as we prefer a booster with a high back, and its crash test results weren't anything to brag about. However, with one of the lowest prices in the group, this easy-to-buckle option makes a great add-on safety option for use when your full-size booster would be too cumbersome or heavy for the job at hand.

| Bottom Line | Great for travel and carpooling, but the quality and crash results make it less appealing as an all-the-time booster | Great choice for most families with better crash testing analysis, easy installation, and cozy seating for kids | Easy installation and use make this a nicer seat, but there are some that offer better crash test analysis | A comfy headrest and good crash test results make this lightweight choice an option that won't break the bank | This basic booster offers disappointing results in most metrics, including crash test analysis, making the low price less appealing |

Our Analysis and Test Results
BubbleBum is the first inflatable best booster seat invented by Grainne Kelly. Kelly came up with the BubbleBum idea when she got frustrated carrying around heavy and bulky boosters for her children. This booster meets and exceeds EU and US requirements. This innovation is the flagship product for a company that now makes a children's neck pillow and activity organizer for the backseat. The BubbleBum sells in more than twenty-eight countries.
Performance Comparison
The BubbleBum was not a top performer in our commissioned third-party tests with MGA Research, but it was better than the other backless booster we tested.

Crash Test
The BubbleBum earned a below-average result for crash test analysis compared to the competition. This analysis combines the sensor data results from commissioned crash testing performed at MGA Research. We ran a test slightly hotter than the federal guidelines and on a more modern-style sled to help determine differences in the competition.
The chest clip sensor data was actually impressive compared to the competition, with a lower recorded amount of G-forces (lower is better) than most. However, the HIC (head sensor) results were not as good as many competitors. The sensor data was in the top third of G-forces, and this brought down its combined analysis result. It still performed better than some of the high-backed options and better than the other backless booster we tested.
Backless vs. High-backed
In general, we feel a high-backed booster provides an added degree of safety by creating a shell similar to convertible car seats for possible side-impact collisions or vehicle intrusion from the outside during a crash. However, that being said, we feel any safety belt-positioning device is better than none, and the BubbleBum fills a niche where boosters are often skipped for the sake of convenience.

The design of the BubbleBum allows most booster age kids to buckle themselves in place because it isn't as wide and has no sides, armrests, or cup holders to hassle with.

Ease of Use
This is a simple booster with not a lot going on. The features and functions all work well and intuitively, giving it one of the highest results in the group for ease of use.
There is no installation method with this booster, and you only need to inflate it using the inflation tube to prepare it for use. The inflation is minimal and something most kids can accomplish without assistance.
The only real trouble our child tester had with the BubbleBum was the shoulder belt retainer. This plastic guide slides on a strap for customization for height, and if you aren't careful, it can easily get twisted at any point in the process.
Parents might have to help younger children guide the shoulder strap through the retainer before pulling the belt across their lap to buckle. Buckling the belt is easy and the BubblBum is so narrow it is not in the way.
The BubbleBum is a standout for size and weight, making it the clear winner for those who require a travel-friendly choice.

Weight and Size
The Bubble Bum is the most compact and lightweight option in the group by far. If carrying a booster or using it on travel or camp and carpooling is in your future, it is hard to find better than the Bum. This booster only weighs 0.9 lbs and is 11.3 inches when fully inflated and ready for use. Seriously, if space or stowing is important, this is the booster for you.

Additionally, this booster deflates and rolls up smaller. It is so small it will easily fit in a small backpack or even some adult jacket pockets. It is a perfect option for little ones who have to tote their own seats.
The BubbleBum is a backless option with no padded headrest or armrests, and the bottom can shift, making it less comfortable than competitors.

Comfort
This booster is narrow and has an inflatable base. It doesn't have much padding, and the fabric is rough and not at all soft.
The booster can shift as little ones shift, and kid testers did a lot of shifting of the booster on longer trips to keep it in place. The edge of the seat is also thicker and sticks up somewhat, which you can feel on the back of the legs and might be abrasive to bare legs wearing shorts. Last, because it is a backless booster, there is no support for the upper body, and car napping could be uncomfortable as kids slouch forward or to the side while sleeping.
Quality
This booster isn't the best quality compared to the competition. The padding is an air cushion, and over time, the cushion struggles to stay inflated, indicating a loss of air pressure somewhere and a quality assurance issue. We also experienced the booster not holding air at all after a trip on an airplane. Hard to say why, but given how travel-friendly it is, this was a bummer.
The fabric isn't as nice as it could be, and the seat's design means it will easily collect grime, and the material may not wear well over time. The Overall fit and finish are somewhat cheap and sloppy. Even though the product is inexpensive, the simple design could have been executed with higher-end materials and more attention to quality control.
The BubbleBum is a good, straightforward choice for kids in camp, carpooling, or travel. It is comparatively compact and easy to stow in a backpack.

Should You Buy the BubbleBum?
The BubbleBum is cheap, making it a shoo-in for many families. It is lightweight and compact when deflated so that little ones can carry it themselves. It is perfect for travel and carpooling, and we've used it with our children on travel and camp outings. Despite having a below-average crash test result, we think it fills the niche of travel-friendly like no other option, and the low price means it could be an excellent secondary seat used for travel only.
What Other Booster Seat Should You Consider?
Despite thinking the BubbleBum is perfect for carpooling or travel, it isn't our favorite for everyday use as we like a high-backed booster and better crash testing results. If budget is a concern, and that is why you are considering the BubbleBum, we think the Diono Cambria 2 is a good budget choice with better crash test results. If you can stretch your budget, or find a sale, we think it is hard to beat the Chicco KidFit Zip Air Plus 2-in-1 is an excellent option good for most families.
