Yes, the car seat is approved following the EU R129/04 safety standards. It's compatible with all i-Size seating positions and has been proven safe in both front- and side-impact crash tests. The belt installation offers flexible, daily use without compromising on safety.

Emerald B grows with your child from birth up to 12 years (40 – 150 cm). Thanks to its universal seat belt installation, it fits virtually any car — no ISOFIX required. Portable, lightweight, and quick to install, it makes switching between vehicles effortless. Four recline positions keep your child comfortable on every journey, from the very first ride home through every stage of childhood. Emerald B is the only car seat you'll ever need.

Emerald B fits children from birth up to 12 years old. For safety, always ensure the seat is undamaged and properly adjusted to your child’s size, age, and needs.

Yes, the newborn inlay is included. With the newborn inlay, you can use this product from birth, without needing to buy an extra infant car seat. It is specifically developed to protect your baby from birth (40 cm) up to 75 cm.

In harness mode (up to approx. 4 years old), your child can weigh up to 21.5 kg. In booster mode (up to approx. 12 years old), the maximum weight is 36 kg.

1. From 0 – 1 year (40 – 75 cm), with newborn inlay in rearward-facing position, using the integrated harness and the seat secured with the vehicles’ seat belt. 2. From 1 – 4 years (61 – 105 cm/21.5 kg), without newborn inlay in the safest rearward-facing position, using the integrated harness and the seat secured with the vehicles’ seat belt. 3. From 15 months – 4 years (76 – 105 cm/21.5 kg) in forward-facing position, using the integrated harness and the seat secured with the vehicles’ seat belt. 4. From 4 – 12 years (100 – 150cm), use in the forward-facing position, securing your child with the vehicle belt.

At Maxi-Cosi, we recommend keeping your child rearward-facing for as long as possible—up to approximately 4 years old (105 cm/21.5 kg)— as research shows it is the safest way to travel. In a frontal collision, rearward-facing travel better supports your child's head, neck, and spine by spreading crash forces more evenly across the body, helping to reduce the risk of serious injury. However, if you prefer, you can switch to the forward-facing position from 15 months (76 cm).

Simply pull the harness adjuster strap until the harness sits snugly against your child’s body. A good rule of thumb: if the harness is tight enough, you should only be able to fit one finger between the strap and your child’s chest.

There's no need to remove the harness when switching to booster mode. Simply store it neatly in the back of the seat, behind the backrest flap, with the shoulder pads attached. No loose parts, no risk of losing anything—ready if you ever need it again.

Use the integrated harness up to a maximum weight of 21.5 kg (approximately 4 years). After that, store the harness away and secure your child using the vehicle's seat belt.

The buckle can be neatly stored inside the seat using the integrated storage compartment. This keeps it safely out of the way when using Emerald B in booster mode, with no loose parts to worry about. Please check the user manual or instruction video for more information.

No, Emerald B is not foldable.

No, Emerald B does not have a rotation function. However, it can be easily changed from the rearward-facing position to the forward-facing position when your child is ready.

G-CELL technology is built into the side panels and headrest, absorbing impact forces and redirecting them away from your child. This ensures better protection for your child, especially for their shoulders, head, and neck.

Emerald B comes with a click-on G-CELL Bumper that provides extra protection on the window side. Simply attach it to the exterior of the G-CELL panel for enhanced side-impact protection. One bumper is included and can be easily switched from the left to the right side of the car, so your child benefits from extra protection wherever they sit.

No, this is not necessary unless you drop the car seat from a great height. When a car seat drops from a low height, this is not comparable to a (serious) crash, and it will not have to be replaced. If you have any doubts, please reach out to our consumer care team.
