Is it safe to use a second-hand Doona car seat?

NEVER put your child in a used infant car seat unless you know its history. A seat may be damaged or have been in a severe crash and have damage that is difficult to see.

Why does the Doona come with  a 5 point harness?

We believe that a 5 point harness better protects a child in case of an accident.

In case of an accident, forces are transferred to the car seat and to the child. The child’s rigid body parts (shoulders and hips/pelvis bone) can withstand the high load forces of a crash better than the soft body parts (lower abdomen). With a 5-point harness the child’s abdomen area is better protected and do not have to endure high loads.

The shoulder straps can be easily adjusted to the correct shoulders height, which ensures that the forces applied in an accident are best transferred to the car seat shell and the rigid shoulder bones of the child.

In addition, in case of an accident a child might be injected from the car seat, the 5-point harness ensures that the child is well secured and keeps the child in the safest position within the protective seat shell.

How does the Doona Side Impact Protection work?

Doona’s unique double wall structure, which enables the folding of its wheels into the Doona™ body, deliver an additional significant safety benefit. The two layers of durable, impact-absorbing plastic, along with additional layers of EPS, foam and textiles provide enhanced side- impact protection which better protects the baby in case of an accident.

How to use the breaks of the Doona?

The rear wheels are fitted with a braking system which allows you to use just one pedal to control both the rear wheels. To apply the brakes, press the red brake lock pedal located next to the right wheel. To release the brakes, press the green brake release pedal located next to the left wheel. The brake must always be on when putting the child in or taking him out. Always use the parking brake when placing and removing the child, or when standing still even for a few moments!

Always use the parking brake when placing and removing the child, or when standing still even for a few moments! Always check that the brake is fully engaged.

How does the Energy-Absorbing Foam work?

Energy-absorbing foam absorbs some of the impact forces that occurs during a crash, keeping your child from absorbing them therefore preventing or minimizing an injury.

The foam also acts as a barrier between your child and the seat shell and any other rigid objects such as the vehicle door or window.

How does the Doona Anti-rebound Protection feature work?

Unlike typical car seats, Doona’s unique structure enables positioning the handle against the back of the seat of the car, thus providing the baby with exceptional Anti-Rebound protection. In case of a collision, the Anti-Rebound handle will absorb the impact and prevent the Doona™ from rotating quickly towards the back of the seat, thus dramatically reducing rebound injuries.

  1. Rigid ISOFIX connectors on the car seat base which connect to standard anchor points in the vehicle seat.
  2. Reinforced adjustable support leg (also called foot-prop).

Some cars made prior to 2006, and all cars made from 2006 are equipped with ISOFIX anchor points.
