The award-winning BubbleBum is the world's first and original inflatable, foldable and portable car booster seat. It's perfect for everyday travel, carpools, playdates, cabs, and vacations. The BubbleBum backless travel car booster is compact, narrow, and light. It's slimline design (13 Inches across) makes getting three car seats across the backseat of your car simple and easy. At BubbleBum the safety of your child is our number one concern. All our car seats are fully tested to meet and exceed all US Federal Motor Vehicle Safety Standards (FMVSS213) and European regulations for car seat safety (R44/04 for Europe). The Bubble Bum is designed for children ages 4 to 11, weighing from 40 - 100 pounds. As with all booster seats, it is designed for use with a standard 3 point adult seat belt that has been approved to ECE Regulation 15 or equivalent. The material we use is similar to that of a lifebelt making it durable and extra safe. The air bladder contains memory foam which adds structural integrity and comfort for your child’s journey. The BubbleBum adds extra boost to position the seatbelt correctly on your precious cargo and prevents your child slouching. It weighs just over 1 pound and comes with a convenient carrying bag and shoulder belt positioning clip. The cover around the air cushion is made of energy absorbing material. The Bubblebum bladder inflates in just seconds with a couple of breaths of air and deflates/packs down just as quickly. When deflated, it's small enough to fit in a child's backpack, purse or a suitcase. BubbleBum's cool, fun and funky designs appeal to kids and parents love the convenience and ease of use. BubbleBum car booster seats are the proud winners of multiple awards since our inception in 2009. These include the JPMA Innovation Award, Parent Tested Parent Approved Award, Mumsnet Best, National Parenting Publications Award, Family Review Centre Best of the Year Award and many more.
