BubbleBum is a lightweight car booster seat that inflates, so it's easy to store and transport when not in use. It's also an ideal choice if you're trying to fit three booster seats along the back seat as it will fit into a smaller space than most solid booster seats. The BubbleBum comes in a convenient carrying bag, and has shoulder belt positioning clips in place of arm rests. It deflates after use, and weighs just 600g, allowing it to be stored in a backpack, flight bag, trunk or even a large purse. It's an ideal choice for holidays, trips to grandparents to play dates. The unisex design is not only comfortable, it can also be wiped clean in case of spilled snacks or drinks. Easy and quick to inflate, it takes less than 30 seconds. Simply blow into the valve at the back. The inflatable inner is made from the same material as life rafts and the seat cover and webbing help the seat stay rigid.
