Group 0/1 seats are designed for children in the 0-18kg weight range. This group of seats is dedicated for children up to about 4 years of age. These are usually seats that allow the transport of children who cannot yet sit up unaided or their height does not allow them to use a car seat in the 9-18kg weight range. Seats in the 0-18 kg range usually have additional padding for the youngest children. This category of child car seats can usually be installed using the ISOFIX connectors, both in forward and rearward-facing positions, but we recommend that you transport your child in a rearward-facing position as long as possible.
