Product description

Designed with a unique, intuitive belt installation system, the Maxi-Cosi Rubi XP car seat makes installation highly efficient for you.


Whatever car you drive, our Maxi-Cosi Rubi XP will certainly fit. The car seat is attached to your car using the car’s seat belt. Check our user manual to follow the steps for a correct installation.


At Maxi-Cosi we have carried over 50 million babies home from the hospital. As a leading specialist in child mobility, your little one’s safety is our top priority. Our intuitive and innovative toddler car seats protect your toddler and help carry your family happily into the future.

Our safe Rubi XP car seat is equipped with a Side Protection System that protects your little one from damaging side impacts. Maxi-Cosi Rubi XP’s SPS (Side Protection System) absorbs the force from an impact, to reduce the risk of injury in case of a side collision. This way your child is always protected.

Safe, comfortable and convenient toddler car seat

Not only does the Maxi-Cosi Rubi XP ensure your little toddler’s safety, it also gives you convenience. The toddler seat contains unique belt routing, to explain exactly how the car seat should be installed. This way, correct installation is assured. Once installed, you can easily place your little one in the car seat, thanks to the convenient harness hooks that keep the harness out of the way.

As your toddler grows, Rubi XP’s safety harness and headrest adjust simultaneously to offer a perfect fit. For your little one’s comfort, Rubi XP has 4 ways to recline in both sitting and sleeping positions.

Since the toddler car seat attaches to a seat belt, it fits most cars.

Removable cover

Your little one could get car sick on the road. Or snacks and drinks might not end up where you want them to. No matter what happens, Maxi-Cosi’s car seat cover can easily be removed and washed in the washing machine.

How can I install the Maxi-Cosi Rubi sturdy in my car?
Please follow the red marking on the product, then tension the car belt before locking the top central belt lock. Read the user manual of the Maxi-Cosi Rubi carefully prior to installation to ensure correct fit in your car and see the installation film available o the product page of this website
When can my child switch from an infant seat to the Maxi-Cosi Rubi?
Make sure your baby’s head is generously protected by the (top of the) car seat. Your baby has outgrown his baby car seat when the top of his ears extend past the top of the car seat shell. Do not switch to the Maxi-Cosi Rubi until this time and keep you baby rearward facing for as long as possible in order to protect the fragile neck and head. Note: it is not a problem if the child’s legs extend beyond the edge of the seat.
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.
