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.

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.
