BoostAPak Vs. BubbleBum – A Comparative Review


Going on vacation and not sure whether to take the BubbleBum or the all-new-to-the-US Safety 1st BoostApak? We put them head-to-head to help you decide which of these ultra-portable booster seats is best for you.

The BubbleBum is for children over 4 years old who weigh between 40-100 lbs; height range 40-57″

The Safety 1st BoostAPak is for children over 4 years old who weigh between 40-80 lbs; height range 43-52″

In this corner, wearing purple (and now also available in black) and weighing in at 1.1 lbs, is the BubbleBum. In the other corner, wearing lime green and weighing in at 3.5 lbs, is the BoostApak. Which one will come out on top?

Here are the two side by side. You can see the overall height of the BubbleBum is somewhat lower. Whether that’s a good thing or a bad thing is a matter of preference. The BubbleBum doesn’t have arm rests, but the ones on the BoostApak aren’t very substantial, so that one’s probably a toss-up.

The BoostApak is a bit deeper overall.

The BubbleBum has the advantage of being lighter than the BoostApak, but it needs to be carried separately or shoved into a backpack, whereas the BoostApak IS a backpack.

My son doesn’t like having to thread and unthread the seatbelt from the BubbleBum’s belt guides each time, but the required belt guide on the BoostApak also proved problematic (at least the first time–the seatbelt can stay in the guide if the booster is staying in the car). He preferred the BubbleBum’s cushiness to the hard seat of the BoostApak, but the BoostApak provided a little more leg support.

Because of the BoostApak’s low height limit, older boostered kids will likely outgrow it early, so that’s an important factor to keep in mind. The BubbleBum, of course, requires you to blow it up, and squishing it back into its carrying pouch can sometimes be a challenge.


How does this battle break down?

The BubbleBum wins three categories: Overall Product Weight, Child Height Limit and Padding/Cushiness.

The BoostApak wins three categories, too: Leg Support, Effort Required to Prepare the Booster, and Ability to Multitask.

Ease of Buckling was a Draw.

So the overall advantage is: It’s a tie!
