BuckleAlarm – an audible harness release alarm!

Children naturally tend to explore objects that spark their curiosity. That is why a special alarm is hidden in the buckle and activates when the harness is unfastened. If your child releases the harness while travelling, you can hear it and respond.

Rotating base – easier access to your child

On every journey, you save time and reduce strain on your back because the EasyTurn 360° rotating base and special harness holders make it much easier to place your child in and take them out of the car.

Enhanced protection in the event of a side impact

Side Impact Guard provides enhanced side protection: attach the special crash pad to the car seat on the door side, and move it to the other side when needed. This creates an additional protective zone that takes the initial impact and absorbs forces that could otherwise reach your child.

Enhanced protection on the vehicle-seat side

The car seat has an adjustable anti-rotation frame. What does this mean? It is an additional barrier that helps prevent the car seat from tilting towards the vehicle seat in a collision and protects your child's head from hitting the backrest. During travel, it also gives your child additional legroom.

Natural bamboo material

The bamboo fabric used for the cover is gentle on your child’s skin and antibacterial, while also providing suitable air circulation. This helps keep your child comfortable even on warmer days.

Better protection for the head and neck

The Tri-Guard technology used in the headrest combines three materials with different properties, including highly resilient Memory Foam. All to help protect your child’s head and neck as effectively as possible.

FAQ

How do I install the Harmony i-Size car seat in the rear-facing position?

The car seat is installed rear-facing for the 40–105 cm range using ISOFIX and the support leg. Children below 76 cm should use the reducer insert. Extend the leg, set the anti-rotation bar, anchor the ISOFIX arms and check the green indicators on both sides. Push the base against the backrest, adjust the leg so that it rests firmly on the floor, and confirm the green leg indicator. After securing your child, rotate the seat to the rear-facing position until it clicks into place and select one of the 5 inclination positions.

How do I install the Harmony i-Size car seat in the forward-facing position?

The car seat is installed forward-facing from 76 cm child height. First, fold the support leg, remove the car seat harness and turn the seat forward until you hear a click. For ISOFIX installation, anchor the arms to the vehicle seat anchors and check the green indicators; installation using the vehicle seat belt is also possible. Guide the shoulder belt through the headrest guide and the lap belt through the lower guide, fasten it and check that it is tight and not twisted. Finally, you can select one of the 5 inclination positions.

How does the buckle alarm work in the Harmony i-Size car seat?

The buckle alarm emits a short audible signal when the car seat harness is unfastened. It informs the parent if the child unexpectedly releases the harness. The alarm is located in the harness buckle.

How do I replace the battery in the Harmony i-Size car seat buckle?

To replace the battery, use a screwdriver to unscrew the cover on the back of the buckle. Then replace the battery and screw the cover back into place. This allows the buckle to use the audible alarm function again.

How do I fold the support leg before removing the Harmony i-Size car seat?

Before removal, press the support leg adjustment button and slide in its extendable section. The latch indicator will turn red. Then fold the leg, hiding it inside the car seat base.

How do I store the five-point harness in the Harmony i-Size car seat?

You can store the harness under the seat cover to prepare the car seat for the next usage stage. Loosen and unfasten the 5-point harness, then undo the metal fasteners on the backrest cover. Remove the harness covers and store this part of the harness, together with the metal connectors, under the seat cover. Remove the buckle from the crotch pad, pass it through the opening in the cover and place it in the compartment in the seat. Close the compartment and refit the cover. To remove the harness, follow these steps in reverse order.

How do I remove the five-point harness from the Harmony i-Size car seat?

To remove the harness, first move the headrest to its highest position and loosen the harness as much as possible. Unfasten the buckle, open the instruction manual compartment and remove the harness from the metal lever and metal buckle inside. Undo the fasteners on the backrest cover, pull out the shoulder straps from the front, and store the lap straps under the cover together with the metal connectors. Remove the buckle from the crotch pad, place it in the compartment under the seat cover and fasten the cover components again.

How do I adjust the anti-rotation bar in the Harmony i-Size car seat?

The anti-rotation bar can only be adjusted when the car seat is installed in the rear-facing position. Press the bar adjustment button and set it to one of the two available positions. Changing the setting helps you fit the bar to the vehicle seat and increase the space for your child’s legs.

How do I adjust the headrest in the Harmony i-Size car seat?

Set the headrest at the height of your child’s shoulders so that the shoulder straps are positioned correctly. Hold the harness tension adjustment button and loosen the harness, then pull the headrest adjustment lever. The car seat has 12 headrest adjustment levels integrated with the harness height adjustment. The harness should not run at ear level or above, or be positioned too low behind your child’s back.

How do I adjust the recline of the Harmony i-Size car seat?

To change the recline, press the adjustment lever and set the seat to the desired position. Gently move the seat until you hear a clear click confirming that it is locked in place. The car seat offers 5 recline levels both rear-facing and forward-facing. When rear-facing, use the reclined position.

How do I rotate the Harmony i-Size car seat to place my child in it?

The seat can rotate 90 degrees, making it easier to place your child in the car seat or take them out. Press the seat rotation button and turn the car seat sideways. Once your child is seated, press the button again and position the seat rear-facing or forward-facing. Finally, try moving the seat—the correctly anchored seat should not change position.

How do I remove the cover from the Harmony i-Size car seat for washing?

The cover is removable and can be machine washed. Set the headrest to its highest position, unfasten the harness and remove the harness shoulder pads. Start with the headrest cover by undoing the metal fasteners, then undo the fasteners and remove the remaining cover elements. To put the cover back on, follow these steps in reverse order.
