i-Size safety without compromise for your growing baby
BABY-SAFE i-SIZE is Britax's first infant carrier that conforms to the new car seat regulation ECE R129 (i-Size). The seat provides safety and comfort for newborns up to 15 months, adjusting and protecting your child as they develop and grow to 83 cm in height.
Room to grow – Suitable from birth to 15 months
BABY-SAFE i-SIZE has been designed to conform to the new car seat regulation ECE R129 (i-Size), and is suitable for newborns up to 15 months, so they can fit into the seat up to 83 cm in height. The infant carrier has a newborn insert for extra support, also offering energy absorption in case of an impact. The insert can be removed and the height of the headrest adjusted, allowing for more space as your child grows.
Travel System ready
On busy days when you and your baby are out and about in the car, you can make the day go smoother by using the infant carrier on a pushchair. Simply take the infant carrier with your baby out of the car and securely click it onto the pushchair – and you're ready to go. All Britax Römer infant carriers can be fitted on any Britax pushchair with the Britax CLICK & GO® adapters.
Weight & SizeWeight: 4.8kg
Especially designed to give extra support to small babies. The included newborn insert with removable, energy-absorbing foam pads reduces the space and offers additional comfort.
Superior Side Impact Cushion Technology (SICT)
Britax's improved SICT offers superior protection in case of a side collision in two steps. It pushes your child away from the impact in a controlled movement and then deforms to absorb energy exerted on your child. To benefit from the protection, simply adjust and adapt the SICT on the side of the car seat closest to the door.
Allows for a more comfortable and more ergonomic position for newborns. Britax patented integral recline mechanism allows you to adjust the flatness of the lying position according to the child's height. The position changes automatically when adjusting the headrest, increasing the space to suit your child's development. The shoulder straps also adjust automatically when adjusting the headrest.
Easy adjustable headrest and harness
Britax padded headrest and harness can easily be adjusted with one hand to suit your child's height. Before you secure your little one in the harness, check to make sure the headrest is in the correct position – just above its shoulders.
Sun canopyThe sun canopy offers protection for your child from the sun (UPF 50+) and wind both in the car and on the pushchair. The attachment points are conveniently located on the sides of the handle so you can carry the infant carrier while the sun canopy is in use
5-point harnessWe believe a 5-point harness is the safest way to secure your child in a car seat because it keeps your child safe and tight in the seat's protective shell. In case of a collision, the harness distributes the forces of the impact across 5 points, two at the shoulders, two at the hips and one where the harness buckles between the legs. This helps to protect your child from all directions of impact.
Easy release with CLICK & GO® adapters
The infant carrier can easily be taken off the base or pushchair so parent can remain in an ergonomic, upright position while lifting the carrier up. Simply use the handle at the back of the infant carrier to unlock it from the base or pushchair and lift it off with ease.
Indicators to check correct fit
Our indicators let you know when the infant carrier is fitted correctly on the base or pushchair. The colour indicators show when the adapters are connected correctly as they change from red to green.

Britax Baby Safe i-Size Flex Base
The most ergonomic yet safe position for your little one
Vehicle seat angles vary from car to car. In cars with inclined seats you can adjust the base angle to a flatter position for your baby with the BABY-SAFE i-SIZE FLEX BASE. This provides the most ergonomic position for your baby while travelling.
Adjustable to the most comfortable yet safe angle for your baby
In cars with inclined vehicle seats, a baby's head may tip forward when they are in an infant carrier. With the BABY-SAFE i-SIZE FLEX BASE you can adjust the base angle, providing an ergonomic, flatter position for your baby, keeping them comfortable and safe. The base can easily be adjusted to 4 different positions for your baby's comfort, and also includes a handy indicator to show you when the angle is too flat.
In cars with inclined vehicle seats, there may be a risk of your baby's head tipping forward when they are in an infant carrier. With our FLEX BASE you can easily adjust the angle of the infant carrier for a flatter, more ergonomic yet safe position of your child during any journey
Height adjustable support leg
The support leg provides extra stability for the infant carrier base via the vehicle floor. It minimises the tilting and rotational movement and reduces the forward movement forces exerted on your child in a crash situation, helping to protect them. For a secure installation, the support leg can be adjusted to suit the height that's best for your car. The easy-to-read indicator shows you when the support leg is positioned firmly on your vehicle's floor.
The integrated handles, conveniently located on the side and front of the base, allow you to easily carry and move the base.
We know that parents of young children have lots of baby items to store so we have designed the infant carrier base with convenient storage in mind. The support leg folds up so you can easily pack it away in your car's boot or at home.
ISOFIX ratchet system
The ISOFIX ratchet system allows the ISOFIX arms to extend so you can easily fit or remove the infant carrier base from the ISOFIX anchorage points in the car. Once the ISOFIX connectors are engaged, push the base until it touches the back of the vehicle seat. This prevents the infant carrier from lifting upwards in case of an impact.
