We just came across this review on Go Graham Go:
Portable and Foldable Booster Seat: BubbleBum
Now that Graham is in school our lives feel about 20 times more busy! We are constantly on the go to either ball games, church, parties, or other events. Because we work outside of the home we have to rely upon others to help us out sometimes. That means that we have to lug around and trade booster seats. Well, life just got a little more simple thanks to a product I was just sent for review called the BubbleBum.
BubbleBum is the first truly portable booster seat that I have ever seen and it is simple to use. Just take the BubbleBum out of the bag, twist off the air valve, blow up until the seat is fully inflated and place cap back on, position the seat in the back seat, pass the seatbelt through both sides of the seat restraint on the BubbleBum and buckle. Once you are finished with the BubbleBum just remove the air valve cap and roll until all of the air is expelled.
While I wouldn’t recommend using this as your primary booster seat, it truly has come in handy for those last minute pick ups! I like to store mine in the trunk just in case I need to hand it over to someone who will be picking Graham up. Keep in mind that this seat will need to be used with children who are 4 or older and weigh at least 40 pounds. I could see this also coming in handy in restaurants if your child needed a little extra boost at the dinner table (although this is not what it is intended for).
