As a parent, you’ll appreciate that Olli belt-positioning backless booster has earned industry awards. But there's an even tougher audience to please: kids who won’t settle for ugly or uncool. With a carrying strap and a quick-release system, Olli gives kids the freedom to carry their own ride wherever they go – from your car to a taxi or even a plane.

Designed for comfort and convenience, the Olli is considered to be one of the best backless booster seats on the market because it’s built like the seat in your car. Clek's Comfort-Cube construction includes an additional layer of padding that protects against numb-bum!

  • Metal substructure provides stability to keep your child in a comfortable and safe position
  • Expanded polypropylene base delivers energy-absorbing capability to reduce the impact of those big bumps in the road
  • Molded polyurethane foam pad maintains its comfy shape for years of cushy feel
  • Clek Rigid-LATCH connectors attach securely to your vehicle’s lower anchors in seconds
  • Quick release system for easy removal by the child
  • Weighs only 5 lbs for easy portability between vehicles, through the airport, or walking through the city streets. It’s the perfect travel booster car seat
  • Fabric on the underside protects your vehicle seats from scratches or snags

CPS Techs

What is a CPS tech?

A CPS tech is a Certified Passenger Safety Technician. Our Cubby Moms who have certified as CPS techs are specially trained on how to properly install car seats and booster seats, ensuring they know everything there is to know about keeping children safe in vehicles.
Through required continuing education courses and hours of personal research and team training, our CPS techs are able to remain up to date on the latest technical information regarding child safety.
Question mark icon

How does a CPS tech get certified?

In order to become certified, each prospective tech must attend The National Child Passenger Safety Certification Training Program. After intensive classroom instruction, they must pass a variety of written tests, demonstrate their knowledge through hands-on skills assessments, and perform safety checks at a check-up event before becoming certified. They learn the ins and outs of car seat installation possibilities, installing car seats in different vehicles, harnessing methods, and more. The car seat and safety industry is constantly changing, so our CPS techs here at The Baby Cubby are an invaluable resource for parents purchasing a new car seat, or for ones who simply want someone to double check that their current car seat is properly installed.
