Product description

Meet Maxi-Cosi’s first i-Size compliant baby car seat: the Rock! It has a unique baby-hugg inlay to give your newborn baby a comfy fit. Its easy-to-use Click & Go installation makes it easy for you as a parent to secure the seat in your car!


Maybe your baby sometimes goes for a ride with his or her grandparents, or with your in-laws. Regardless of how many different cars your little one goes for a ride in, our Maxi-Cosi Rock always fits. The baby car seat can be attached to your car seat’s safety belt or to your car’s ISOFIX anchorage points. The installation is clearly explained in our user manual, guiding you step by step for a secure fit.

For installation using ISOFIX, you will need an ISOFIX base. Attach the base to your car’s ISOFIX connectors and leave it installed in the car. This way, our Rock car seat is snapped onto the base with a simple "click”, every time you need to get in the car. Visual indicators on the base notify you when your Maxi-Cosi car seat is correctly installed and you are ready to "go”.

Rock can be installed in combination with the FamilyFix One i-Size base.

We want you to feel secure about the installation of your baby car seat. That is why we collected our safest travel tips in order to help you as parents, feel sure about your little one’s safety in the car.



At Maxi-Cosi we have carried over 50 million babies home from the hospital. External crash test centres, such as the German automobile organisation ADAC (Allgemeiner Deutscher Automobil-Club), regularly test our Maxi-Cosi car seats on dynamic safety and ease of use.

When the ADAC tested the Maxi-Cosi Rock with the FamilyFix One i-Size, they got high scores for safety. Our comfortable Rock car seat is equipped with a Side Protection System, meaning that in the event of a hard side impact, Maxi-Cosi Rock’s SPS (Side Protection System) reduces the risk of your baby getting injured.

Additionally, we have also improved the Rock’s impact-absorbing material, making the baby car seat compliant with the latest European i-Size safety standard for car seats. It gives your baby maximum safety.

The Rock also has a good rating on convenience of use, thanks to its easy-to-use Click & Go installation with an ISOFIX base. To reduce the risk of installing it the wrong way, at Maxi-Cosi, we always recommend to install our Rock car seat with the FamilyFix One i-Size base. Most first-time parents install our baby car seats correctly, thanks to its easy Click & Go installation.


A safe place for your baby

Because we care about giving parents the safest car seat, we designed our Maxi-Cosi Rock to comply with the latest i-Size car seat regulation. By adding improved impact-absorbing material to the top side of each wing, the Rock is an i-Size car seat, which means it’s a super safe place for your baby in the car.

Not only is our baby car seat safe, it is comfortable for your baby and convenient for you as a parent. The seat has extra padding, and it includes a comfortable baby-hug inlay. This inlay is designed for your newborn baby’s perfect fit, and for enhanced comfort and safety.

The Click & Go installation — in combination with the ISOFIX base – allows you to attach the Rock to the base with a simple "click”. To avoid installing it the wrong way, the base notifies you when it has been properly attached. You can continue using the Maxi-Cosi base with a toddler car seat for longer rear-facing travel, which experts recommend for up to 4 years. That’s because it gives your little one’s head and neck better protection. Since you are able to use the ISOFIX base for up to 4 years, you get the best value!


Removable cover

Since our Rock will get dirty after daily use, Maxi-Cosi’s car seat cover can easily be removed. It is machine washable for easy cleaning, no matter what happens.


Travel system

Going for a relaxing stroll in the park, a short visit to see your parents, or a quick stop at the supermarket? Use our i-Size car seat together with a stroller by clicking the Rock onto it.

Create a complete and practical travel system, by combining our car seat with a Maxi-Cosi stroller. They make the perfect match!

Can I install the Maxi-Cosi Rock with base on the front passenger seat?
Yes, you may install the Maxi-Cosi Rock onto a compatible base on the front passenger seat if that seat has ISOFIX anchor points. VERY IMPORTANT to make sure that the airbag has been deactivated. Most cars do not have ISOFIX anchorages in the front passenger seat though.
Can I install the Rock by the car's seat belt?
Yes you can install the Rock by the car seat belt, just like all other baby car seats of Maxi-Cosi. The safety level of an installation by car seat belt gives an ECE R44/04 safety performance though, so we recommend to always use the Rock on any of the compatible Maxi-Cosi i-Size bases in order to achieve the highest, i-Size (R129) compliant safety performance.
Which are the compatible i-Size bases to use in combination with Maxi-Cosi Rock?
The Rock is compatible with the 2wayFix, FamilyFix One i-Size, BabyFix and 3wayFix bases. In combination with any of the aforementioned bases Rock complies with the stringent i-Size (R129) safety regulation.
Can I adjust the height of the safety harness?
The height adjustment of the safety harness is regulated by means of the baby-hugg inlay. For newborn babies with a maximum lenght of 60 cm the baby-hugg inlay should be used in order to ensure the perfect safety harness height in the shoulder area. For babies with a length as from 61 cm up to 75 cm we recommend to remove the inlay. This way the lying position is lower providing a perfect safety harness height in the shoulder area again.
How do I remove the Rock from my stroller?
You can remove the Rock from a stroller by pushing simultaneously on two grey buttons that are located just next to the carrying handle on the side of the car seat and pulling the seat in an upward direction. Please make sure you always place the car seat rearward facing and not forward facing on the stroller. In combination with Maxi-Cosi and Quinny stroller frames the Rock is very easy to release with one hand thanks to the memory buttons.
The Maxi-Cosi Rock complies to the i-Size (R129) regulation. What does that mean?
i-Size (R129) is the latest active regulation that aims to make car seats even safer than before. i-Size (R129) car seats offer ISOFIX installation, rearward- or lateral-facing travelling up to at least 15 months, and improved safety standards for additional protection for head and neck. To find out more about i-Size (R129) you can follow this link:
What accessories for the Rock are available?
Maxi-Cosi offers these accessories for the Pebble Plus: footmuff, summer cover, rain cover and mosquito net. Please visit the Maxi-Cosi website for more information.
When should I remove the Baby-Hugg inlay from the Rock?
The baby-hugg inlay is especially developed to offer additional comfort and safety for small babies. A baby outgrows the baby-hugg inlay on average when he/she is around 60 cm tall. You can consequently remove this inlay from the Rock and use it without.
Where can I find the integrated sun canopy on the Maxi-Cosi Rock?
On the back of the Rock coming out from the rim you will find two small taps that are attached to the sun canopy. You can pull on these tabs to extract the sun canopy and attach it to the carrying handle.
Why is the classification on the Maxi-Cosi Rock indication in height (or cm) indication and not in weight (or kilo)?
The Maxi-Cosi Rock complies to the latest i-Size (R129) regulation and this change is part of i-Size. It is done in order to make it easier for parents to choose the right car seat for their child, and thereby minimize premature up-sizing of the car seat. The Maxi-Cosi Rock is for babies from birth to 75 cm tall.
Why is there a 12KG weight limit on the Rock instruction sticker?
In i-Size (R129)  child car seats are classified in a length size range, but the regulation also requires to indicate a maximum weight of the baby. The Rock is suitable for babies from birth (approx. 45 cm) until 75 cm. The 12kg weight limit on the Rock refers to the 95 percentile weight of a child of 75 cm. This means that only 5% of the children will be over 12kg weight by the time they reach 75 cm.
Can I wash the baby-hugg inlay and cover of the Rock in my washing machine?
Yes you can wash both the baby-hugg inlay as the cover of the Rock in your washing machine but at maximum 30 degrees and using a delicate washing program.
