Detailed features

i-Size certification

Bastiaan One i-Size complies with the stringent i-Size standard, which guarantees the highest level of safety. The car seat is designed for children measuring from 40 to 150 cm.

Stringent safety standards

The car seat’s headrest is reinforced with Memory Foam, which effectively absorbs impact forces. Advanced side protection provides additional protection for your child in the event of a collision. The high quality of the product is also reflected in its base, reinforced with glass fibre to further increase the strength of the entire construction.

Straightforward installation

The car seat is installed using the ISOFIX system and Top Tether. ISOFIX is the most recommended installation method and minimises the risk of making an error when securing the car seat. For the oldest children (100–150 cm), use the vehicle’s safety belts. Special guides feature indicators that change colour from red to green to show that the car seat has been secured correctly.

Comfort for your child

The seat is covered with EPE foam, providing comfort even on the longest journeys. The internal harness adjustment mechanism also helps you secure your child, allowing the harness to be tightened with one pull. A system of protective covers on the shoulder straps, waist straps and central buckle helps protect your child’s delicate skin from chafing.

360° EasyTurn rotating base

The handy 360° EasyTurn rotating base lets you secure your child precisely and take them out quickly and conveniently. You can turn the base towards the door for easy access, without straining your back. The internal harness adjustment mechanism also helps you secure your child, allowing the harness to be tightened with one pull.

RWF and FWF installation

As the car seat grows with your child, it can be installed both rear-facing and forward-facing. For the oldest children (100–150 cm), use the vehicle’s safety belts.

Reducer insert

The reducer insert with the Dri-Seat system not only supports good ventilation but also helps ensure an anatomically correct position for the smallest children.

Grows with your child

The 13-position headrest adjustment, integrated with the harness height adjustment, allows the car seat setup to adapt to your child’s changing needs. The car seat features 4-position backrest inclination adjustment in both forward-facing and rear-facing configurations, so you can choose the most comfortable position for your child.

FAQ

How do I install the Bastiaan One i-Size car seat rear-facing for a child measuring 40–105 cm?

For a child measuring 40–105 cm, install the car seat rear-facing using ISOFIX and Top Tether. Place the car seat on the vehicle seat, extend the ISOFIX arms and insert them into the anchor points until you hear a click. The green indicators next to the ISOFIX buttons must be visible on both sides. Press the base against the backrest with a left-to-right motion, rotate the seat to the rear-facing position and check that it does not change position. Finally, choose one of the 4 inclination positions.

How do I install the Bastiaan One i-Size car seat forward-facing for a child measuring 76–105 cm?

For a child measuring 76–105 cm, install the car seat forward-facing using ISOFIX and Top Tether. First, rotate the seat forward-facing and check that, once correctly anchored, it cannot change position. Then place the car seat on the vehicle seat, extend the ISOFIX arms and anchor them in the points until you hear a click. The green ISOFIX indicators should be visible on both sides. Press the base against the backrest with a left-to-right motion and choose one of the 4 inclination positions.

How do I install the Bastiaan One i-Size car seat forward-facing for a child measuring 100–150 cm?

For a child measuring 100–150 cm, position the car seat forward-facing, stow its harness and secure the child with the vehicle’s 3-point seat belt. Position the seat forward-facing, place the car seat on the vehicle seat and select the sitting position. You can use ISOFIX: extend the arms, anchor them until they click, check the green indicators on both sides and press the base against the backrest. When installing without ISOFIX, skip these steps. Adjust the headrest, then route the shoulder and lap sections of the seat belt through the appropriate guides.

How do I fasten and unfasten the harness in the Bastiaan One i-Size car seat?

To fasten the harness, connect the two buckle tongues and insert them into the buckle until you hear a click and see the green indicator next to the buckle button. Before placing your child in the seat, loosen the harness using the tension adjustment button. To unfasten it, press the red button on the buckle. After fastening the harness, adjust the headrest and tighten the straps using the adjustment strap. The harness should fit snugly against the child’s body and must not be twisted. The lap straps should lie low across the pelvis. A child measuring 40–60 cm may use the seat only with the reducer insert.

How do I adjust the headrest in the Bastiaan One i-Size car seat to suit my child’s height?

Loosen the harness by holding down the tension adjustment button, then pull the headrest adjustment lever. The height of the shoulder straps changes together with the headrest height. Position them at your child’s shoulder level, not at or above ear level and not behind the child’s back. The car seat has 13 headrest adjustment positions.

How do I stow the 5-point harness in the Bastiaan One i-Size car seat?

The car seat harness is stowed when switching to the configuration for a child measuring 100–150 cm. First, release it using the central red buckle button. Then remove the reducer insert and the harness buckle cover. Undo the metal fasteners located at the top of the backrest cover.

How do I detach the Bastiaan One i-Size car seat from the ISOFIX anchors?

To detach the car seat from ISOFIX, press the ISOFIX release levers on both sides. The ISOFIX arms will then be released from the anchors in the vehicle seat. Do this after removing the child from the car seat.

How do I adjust the seat inclination in the Bastiaan One i-Size car seat?

To change the inclination, press the inclination adjustment lever and set the car seat to the desired position. There are 4 backrest inclination adjustment levels. The adjustment works in both forward-facing and rear-facing configurations.

How do I rotate the seat on the Bastiaan One i-Size car seat?

Press the seat rotation button, then position the seat rear-facing or forward-facing. After changing the position, try moving the seat. A correctly anchored seat should not allow its position to be changed.

How do I remove and refit the cover on the Bastiaan One i-Size car seat?

To remove the cover, position the headrest at its highest setting, unfasten the harness and remove the harness protection pads. Start with the headrest cover. Then undo the metal fasteners and remove the remaining cover elements from the shell. Refit the cover by following these steps in reverse order.

How do I clean and care for the Bastiaan One i-Size car seat?

The cover should be hand-washed at a maximum temperature of 30°C. Do not tumble dry it or expose it to sunlight while drying. This helps you keep it in good condition every day.

How do I install the Bastiaan One i-Size car seat rear-facing for a child measuring 40–105 cm?

For a child measuring 40–105 cm, install the car seat rear-facing using ISOFIX and Top Tether. Place the car seat on the vehicle seat, extend the ISOFIX arms and insert them into the anchor points until you hear a click. The green indicators next to the ISOFIX buttons must be visible on both sides. Press the base against the backrest with a left-to-right motion, rotate the seat to the rear-facing position and check that it does not change position. Finally, choose one of the 4 inclination positions.
