PORTABLE AND PACKABLE | Car seats no longer have to be heavy, bulky and impractical. The hiccapop UberBoost portable car seat inflates with only a few breaths (takes less than 20 seconds), and installs easily and quickly. Deflates and rolls up tightly in its own travel bag for compact fit in suitcases, carry-ons, large purse or backpack.
CERTIFIED SAFE FOR YOUR MOST PRECIOUS CARGO | Your child deserves a comfortable and safe car seat for those quick journeys in rental cars, taxis, Uber rides, on school trips or in car pools. Meets or exceeds all federal standards for car seat safety (FMVSS213 Federal Motor Safety Standard for USA).
STURDY, STABLE, SECURE | Non-skid base is designed to sit firm and steady on leather, vinyl or cloth seats. Provides soothing stability while riding and limits movement in case of an accident. Gentle on your upholstery.
PRACTICAL DIMENSIONS | Narrow yet roomy design allows you to fit 3 UberBoost inflatable car seats across the back seat of smaller vehicles, or fit 1 in between 2 traditional car seats. Perfectly accommodates large families, car poolers and busy soccer moms!
SECURITY AND COMFORT | Buoyant and extra comfy for small bottoms. (Your little one will love the ultra cushiony design!) Positioning clips ensure that child’s belt fits properly and comfortably across the lap rather than dangerously digging into the stomach, preventing internal damage in the event of an accident.
