About The Brand

Nachfolger built the world's lightest folding kids car seat. It's simple - because we need it. As fathers, we've had enough of carrying around bulky contraptions. And since they have had experience with car seats, they thought up ways to improve them. 
That's how the Nachfolger HY5 was invented.


Keeping children safe is our utmost priority. As such, we have a strict no-return policy for child safety products as it is not possible to ascertain the complete history (how it was used/if any parts of the product might be compromised) of the product before considering resale.
