The new Baby-Safe 3 i-Size from Britax Römer offers the highest level of protection for your baby. The baby seat corresponds to the new i-size standard and is therefore based on the height of your child and not on weight, so you have more coordinated security. The extra flat lying position is also perfect for transporting your little one, as the neck muscles are not yet sufficiently developed to sit upright.

With the removable newborn insert, you can use the Baby-Safe iSense baby seat for a longer time. The baby seat grows with your baby up to the age of 15 months. The headrest and the belt can be adjusted several times and therefore optimally to the size of your baby. The lying position can also be adjusted and thus offers ergonomic seating comfort for your child. You can also adjust the sitting position (upright or lying down) with the Flex Base, up to 6 different angles are possible.

For more comfort and safety - Flex Base iSense

In the course of the first year of life, you will insert and remove the infant carrier many times in the car. For shopping, bring siblings to the day care center, to the pediatrician or to visit friends and family.

The Flex Base iSense makes it easier to install and remove noticeably. One click and the capsule is securely fastened in the car. Indicators also show you when the car seat is correctly attached. The height-adjustable support leg provides additional stability. Again, a Frabindikator indicates the correct setting. The patented ISOFIX system from Britax Römer reduces the forward movement of the seat in the event of an impact and directs the forces downwards. This means that your baby is even better protected and the risk of head or neck injuries is reduced.
If your baby is too large or too heavy for the baby seat, you can use the additional seat (Dualfix iSense from approx. 15 months to approx. 4 years) and also mount it on the Flex Base iSense. So you have 1 base, 2 seats and the best safety and comfort for your child for four years.
