Getting your little one in and out of their car seat has never been this easy.

Your little one can travel in Pearl XL Slide Pro all the way up to 12 years old. They can start using it from 3 months (61 cm) and even from birth (40 cm) with the Newborn inlay accessory. After your child reaches 4 years old (105 cm), the seat switches easily from harness to booster mode. Simply remove the car seat base and secure your child with the vehicle belt and integrated connectors to attach the seat to the car for extra stability.

FAQs

Got unanswered questions? Contact Us

Is Pearl XL Slide Pro an i-Size compliant car seat?

Yes, Pearl XL Slide Pro complies with the latest and safest EU R129/04 regulation, meaning it fits in all i-Size compliant cars and has passed frontal and side-impact crash tests.

What makes Pearl XL Slide Pro unique?

Pearl XL Slide Pro is the all-ages car seat with SLIDETECH®2, designed to simplify daily life for parents. From birth up to 4 years / 16.5 kg) use the 5-point harness with the FamilyFix Slide Pro base (sold separately) to effortlessly rotate and slide your child toward you. Once your child reaches 4 years/16.5 kg, switch to booster mode: remove the base, store the harness, use the integrated connectors for stability, and secure with the vehicle belt.

From and to what age can I use Pearl XL Slide Pro?

Pearl XL Slide Pro can be used by children from approx. 3 months (61 cm) to 12 years (150 cm). With the optional Newborn Inlay (sold separately), it’s ready from birth (40 cm), offering comfort and safety from day one. For safe use throughout its lifespan, ensure the seat is undamaged, correctly adjusted, and converted to match your child’s length, age, and needs.

What is the maximum allowed child weight for the Pearl XL Slide Pro?

The maximum allowed child weight is 16.5 kg for harness mode and 36 kg for booster mode.

How tight should I fasten the safety harness system?

To fasten the harness correctly, make sure your child is securely restrained in the car seat. Pull the harness adjuster strap until the harness fits snugly against your child’s body. A properly tightened harness should allow no more than one finger to fit between the strap and your child.

When do I need to switch to the forward-facing position?

Pearl XL Slide Pro offers safe rearward-facing travel up to 4 years, with the option to switch to forward-facing from 15 months. At Maxi-Cosi, we recommend rearward-facing as long as possible — it’s proven to be the safest way to travel. After 4 years or 16.5 kg, the seat converts into a backrest booster, usable up to 12 years.

Which car seat base is compatible with Pearl XL Slide Pro?

The FamilyFix Slide Pro base is compatible with Pearl XL Slide Pro, enhancing safety, comfort, and convenience. It features SLIDETECH®2 that allows the seat -in harness mode- to slide out up to 27 cm at a wide angle and fits in any car, regardless of wheel arch shape.

How does SLIDETECH®2 work?

SLIDETECH®2 is built into the FamilyFix Slide Pro car seat base, letting you rotate and slide your car seat right out of the car. It slides out up to 27 cm, making it easier than ever to lift your child in and out, no backaches or head bangs.

How do I operate SLIDETECH®2?

Paired with the FamilyFix Slide Pro base, SLIDETECH®2 allows you to easily slide the car seat out of the car by rotating it 90° (facing your child towards you) and pulling the seat toward you - this can even been done with one hand. No additional button is needed to activate the sliding function — up to 27 cm.

What's the difference between SLIDETECH® and SLIDETECH®2?

While the original SLIDETECH® delivers a functional 17 cm sliding car seat solution, SLIDETECH®2 takes innovation further - offering a full 27 cm slide-out, a wider pivot angle, and enhanced compatibility with a broader range of vehicles. Designed with comfort, safety, and accessibility in mind, SLIDETECH®2 is the smarter choice for those who seek easier child installation. Experience a new level of convenience with SLIDETECH®2: Effortlessly slide, spin and go!

What is G-CELL Side Impact Protection?

G-CELL technology is built into the side panels and headrest, absorbing impact forces and redirecting them away from your child. This ensures better protection for your child, especially for their shoulders, head, and neck.

What is the G-CELL Bumper and how does it work?

Pearl XL Slide Pro comes with a slide-on G-CELL Bumper providing enhanced protection on the window side. Simply slide it onto the exterior of the G-CELL panel to ensure even better side impact force absorption.

What does Eco Care mean?

All our car seats are made with sustainable, 100% recycled Eco Care fabrics. They offer the same soft, breathable quality you expect from Maxi-Cosi while using 75% less energy, 85% less water, and cutting CO2 emissions by 75%. Coral Slide Pro fabrics contain 46 recycled 500 ml rPET bottles.
