What are ECE R44 and ECE R129?

ECE R44 and ECE R129 are international safety standards for child car seats.

A car seat must be approved under one of these standards in order to be sold and used in Europe.

ECE R44

  • Older safety standard
  • Seats are classified based on the child’s weight

ECE R129 (i-Size)

Both standards are legally accepted as long as the seat is properly approved and installed correctly.
