CLEK Fllo Convertible Car Seat Features:


Clekfoonf ExtendedClekfoonf ExtendedSafety Features That Matter

Extended Rear-Facing

Designed to international best practice allowing for most kids to remain rear-facing until their fourth birthday.

Anti-Rebound Bar

Prevents rebounding when rear-facing in a frontal collision and rotation in a side-impact collision; while also improving installation by nesting firmly and evenly into the flat part of the vehicle seat

Advanced Side-Impact Protection System

Protects the child with its adjustable headrest, deep side wings, and dual layers of energy-absorbing EPP foam for maximum side-impact protection.

Energy-Absorbing Crumple Technology (EACT)

Energy-Absorbing Crumple Technology (EACT) transfers crash forces away from the child and into the aluminum honeycomb deformable cores that are integrated into the seat base.

Fllo Safety Highlights:

What sets fllo apart?

  • Rebound bar provides 1-2 inches of extra legroom for the rear-facing child as they grow.
  • Removable seat cushion makes the rear-facing belt path easy to access. The cushion can come off without having to uninstall the seat, so it's easy to clean.
  • Built-in rear-facing lock-offs improve ease of use by tensioning and removing excess slack from the belt.
  • Adjustable crotch straps and 6 different harness heights provide flexibility in adjustment to fit a wide range of sizes and ages of children.
  • Meets or exceeds all applicable Federal Motor Vehicle Safety Standards (FMVSS213)

Did you know?

  • Motor vehicle crashes are the leading cause of death for children between the ages of 1 and 14 in North America.
  • The American Academy of Pediatrics recommends that children ride rear-facing as long as possible, preferably until they reach the limits of their rear-facing convertible seat.

Clek: Parental Instinct:

Sure, you have to make a lot of compromises as a parent. But when it comes to the safety of your kids? No way. When CLEK became parents, CLEK realized that none of the available car seats offered everything CLEK wanted: best-in-class safety, convenience and style. Every car seat seemed to come with a trade-off. More safety meant less convenience. More convenience meant less style. CLEK knew that the could do better, so CLEK did.

Safety Obsessed, so you can Enjoy the Ride:


Safety is the reason CLEK is doing this in the first place - to protect the well-being of CLEK children and yours. From thoughtful design to impact-reducing materials, all of CLEK's baby and toddler car seats and booster car seats are equipped with best-in-class safety features- and CLEK plans to keep on raising the bar when it comes to protecting your kids

Free of Brominated and Chlorinated Flame Retardants, Because We're Parents Too:

CLEK design car seats that use for our own kids. That's why CLEK became the first car seat company to remove brominated and chlorinated flame retardants from car seats in 2014. In 2018, CLEK introduced the world's first convertible car seats and booster seats made without any added flame retardants, featuring ethically sourced 100% Merino wool.
