WhizRider is the most compact, safe, and portable car seat option. This booster seat alternative is an award-winning, harness-style system that is worn like a vest and secured using built-in guides that work with your vehicle’s seat belt for optimal placement.


  • Weighs less than 1 pound 
  • Small as a medium cup of coffee
  • Convenient and easy to use – install in under 20 seconds
  • Perfect for ride-sharing, 3 in a row, for family travel and on-the-go
  • Tested safe – meets U.S. NHTSA regulations (FMVSS213)
  • WhizRider keeps the vehicle safety belt in optimal position (around top of shoulder, over upper thighs), preventing children from sliding forward or submarining.


Designed with your child’s safety in mind, WhizRider has undergone vigorous crash testing under US and European requirements, and actually exceeds US child restraint system standards.


Developed for modern families on-the-go, the WhizRider easily folds into a coffee-cup sized carrying case for easy portability. This ultra-portable, lightweight solution weighs less than one pound and installs in fewer than 20 seconds. As a result, WhizRider makes carpooling, ridesharing with Uber or Lyft, and using public transportation like taxis, buses, and trains a breeze. Additionally, the unique vest construction makes it easy to fit three car seats across, so you never have to worry about fitting everyone in safely again.


The result is a restraint vest that gives parents peace of mind and goes where you go.
