The Maxi-Cosi Opal is a high comfort convertible car seat with simultaneous height and width adjustment to always ensure optimal comfort from baby to toddler. Luxuriously padded, Opal adjusts from sitting to sleeping for the most enjoyable of journeys. Long-lasting car seat, it is first used as a rearward facing baby car seat from birth to approx. 15/18 months for extra head & neck protection (This is 3 to 6 months longer than infant carriers). Then Opal can be easily & safely turned to face forward.


Install the Maxi-Cosi Opal in your car, using your car’s seat belt. You will enjoy the flexibility of Opal’s seat belt installation: not all cars have ISOFIX connectors, but you can still switch Opal from one car to another.

In addition, Opal offers the following features: a headrest for maximum protection from side impacts; a 5-point integral safety harness ensuring that your child is securely restrained; intuitive belt routing that makes it easy for you to install the car seat; and anti-slip shoulder pads assuring high restraint performance in case of a frontal impact.

One car seat, 4 years of comfort and safety

If you look for a comfortable long-lasting car seat that grows with your little one from birth until 4 years of age, and the capacity for rear-facing travel, then the Maxi-Cosi Opal is ideal for you!

Suitable for two age groups, Opal enables rear-facing travel until approx. 15 months of age, offering the best protection for your baby’s fragile head and neck. Installed with a seat belt, the Opal car seat is compatible with all cars.

Opal can be used as a rear-facing baby car seat first (group 0+), and then easily switched to a forward-facing toddler car seat (group 1). You don’t even need to reinstall the full belt routing!

We have also made sure your little one is comfortable. With some luxury padding, Opal can be adjusted from a sitting to a sleeping position to make all trips as enjoyable as possible. As its height and width are adjustable, your baby will always enjoy a nice and snug fit in our Opal car seat.

My child climbs out of the belt system on the car seat.
The same principle applies to all car seats and means that your child cannot create extra space if there is no extra space to begin with. Some children have shown us that, with only a minimum of slack in the belt system, they can get a hand between the buckle and their stomach and then, by moving it towards their head, they can get an elbow under the belts – but this requires a very flexible shoulder. These children display a tremendous desire to free themselves from their car seat. Child safety in the car and freedom of movement are not compatible in principle. To transport a child not only safely but also comfortably, a slight amount of slack in the belt system is needed. If the belt is pulled extremely tightly and the child is sitting calmly in the car seat, experience has taught us that all car seats are the same when it comes to 'climbing out of the car seat'. We see a similar pattern in children ages 1-4 years in car seats of various types and from various manufacturers. The belt system is a closed system that keeps the child in the same position continuously - during normal car trips as well as during a sudden stop or accident. This system is closed by securing the child when tightening the belts. If this is done properly, the belts cannot be loosened during use (if this does happen, we ask that you contact our Service Department through the retailer where you bought the product).
The belts are not the same length. Why is this?
Uneven belts may be caused by the incorrect guiding of the harness system. Check at the back of the car seat that the belts are not twisted and that the pull belt (that runs forward at the bottom of the shell) is in the middle of the system. Also check that the belt can move easily to and fro through the shoulder openings. For smooth movement, the belt buckle should be flapped forward completely. This belt buckle operates by releasing the belt tensioner. If the problem continues after you have checked this, consult your retailer.
Why do babies have to travel in a rear-facing position?
Babies have a large and heavy head compared to the rest of their body. In addition, their neck muscles are not yet fully developed. If the baby is transported in a forward-facing position, his or her head will be thrown forward in the event of a head-on collision. This can cause serious neck injury and may even be fatal. By placing the baby in a rear-facing position, the forces exerted during the crash will be distributed across the baby’s entire back. Discover more about rearward facing travelling.
What is the right position for the headrest of my child car seat?
The child's head has to be totally protected and should not exceed the headrest.
How long can I use the Maxi-Cosi without a break?
This is subject to a lot of misunderstanding. This is generally said and written out of concern for babies and, in a nutshell, boils down to the fact that a baby car seat such as a Maxi-Cosi Citi SPS or Maxi-Cosi Cabrio(Fix) and Maxi-Cosi Pebble should not be used excessively. Children should not lie in a fixed position for too long unnecessarily. They must be given the opportunity to develop their motor system and arm, back and neck muscles. As manufacturers of the first car seat for babies in Europe, the Maxi-Cosi, naturally we have been including this in our instructions for many years. So do not place a baby in his or her seat for the entire day for reasons of convenience, but give him or her the opportunity to develop. This also applies to front pack carriers and all other products in which a baby sits, hangs or lies in a stationary position. However, this is not problematic whatsoever when taking a relatively long car journey or holiday trip once in a while. Our advice is as follows: stop once every 2 hours. After all, the baby must also eat and be changed on a regular basis.
What is the right position/height for the safety harness?
The harness straps should be placed at the level of the shoulders, not coming from above nor below. The headrest should be adjusted in consequence, keeping the harness at the level of the shoulders.
Can I recline Opal in rearward facing ?
In rearward facing, Opal has a unique recline position. This natural recline has been designed to offer best protection to the child in case of collision. It is then important to have this fixed position. For extra comfort, a new-born cushion is included to offer an optimal recline. Nevertheless, all cars are different, and the car seat may be positioned too upright if the vehicle seat has a deep angle. You may adjust the vehicle seat recline if possible or fill the seat hole without changing the car seat belt routing.
From what age can the support pillow be removed from the Opal ?
The support pillow provides your baby added comfort right after birth. We recommand you to use it from birth to approximatly 5,5kg. Once you found your baby too tight in the car seat, and exceeds 5,5kg, you can then remove the support pillow, and use the regular seat.
How long can I install my baby rearward facing on Opal ?
Opal has been tested to be used rearward facing until 13kg. With this large seat, you can easily adjust in width and height, you can install comfortably your baby until approximatly 15m, and even more if he weights less than 13kg. Of course, Opal can be used from birth, but is also perfect car seat to use right after a safety carrycot or an infant carrier, when the baby is not fitting anymore in these baby seats, but still need to be installed rearward facing for a longer time. Looking at the car seat regulation, you can install the baby from 9kg in forward facing, but we recommand to keep your baby until 13kg in rearward facing. A informative measuring scale is placed closed to the headrest to help you to know when it could be time to switch from rearward to forward facing position.
How to switch Opal car seat from rearward to forward facing ?
To change the position of Opal, you should remove the belt installation, press the switching button located on the car seat base, and simultaneously rotate the seat. You should then reinstall the seat in forward facing. The switching button should be in front of the selected position (here forward facing position). We invite you to look at the Opal instruction manual for a more details in the Maxi-Cosi website.
When can I switch Opal from rearward facing to forward facing ?
According to the car seat regulation, you can use Opal in forward facing position (group 1) from 9kg (around 9 months), but we strongly recommand you to keep your child rearward facing until 13kg (approximatly 15/18 months) to better protect the baby's fragile head and neck in case of accidents. To help you to know when your can switch from rearward facing to forward facing, you can use the informative measuring scale integrated closed to the headrest.
Why do babies and young toddlers have to travel in a rearward facing position
Babies have a large and relatively heavy head compared to the rest of their body. In addition, their neck muscles are not yet fully developed. If the baby is travelling in a forward-facing position, his or her head will be thrown forward in the event of a head-on collision. This can cause serious neck injury and may even be fatal. By placing the baby in a rear-facing position, the forces exerted during the crash will be distributed across the baby’s entire back. It is therefore safer to travel rearward facing for babies until at least 13kg (approximately 15/18 months).
Why there is a measuring scale (blue/red label) ? How to read it ?
This measuring scale is an informative label to help you to know when it could be time to switch from rearward facing to forward facing. In a daily basis, it's not easy to know the exact weight of your growing baby, and you may want to install quickly your child in forward facing because it's easier to see you child, but you should not placed a baby before at least 9kg, and ideally 13kg in forward facing. The goal of this label is clearly to avoid babies to be installed too early in forward facing position. By adjusting the headrest, you will see if the seat has still to be installed rearward facing (blue color) or can be installed forward facing (red color). Of course, it's an indicator, but you should always check if your child weights at least 9kg (ideally 13kg) before installating the seat in forward facing position.
