You just want to keep saying it over and over. BubbleBum. BubbleBum. Ok, maybe it’s just me. Giggle. The BubbleBum inflatable booster seat for kids aged 4-11 is the coolest thing to help busy moms since the invention of the pool boy. It checks in at less than 1 pound and inflates in minutes. When not in use, simply deflate the booster seat, roll it up and stow away in the trunk or backpack for the next use. Perfect for travel with rental cars, cabs, carpooling and restaurants.
