Description

Only compatible with the Maxi Cosi FamilyFix Slide Pro ISOFIX Base

The Maxi-Cosi Pearl XL Slide Pro, Authentic Graphite is designed to grow seamlessly with a child from their earliest days through to around 12 years old, offering a long-lasting and adaptable car seat solution for modern family life.

Key Features: 
  • Grows with your child from birth (40 cm) with the optional Newborn inlay through to approximately 12 years old.
  • Suitable from around 3 months (61 cm) on the FamilyFix Slide Pro base, with extended use in harness mode up to 4 years (105 cm / 16.5 kg).
  • Converts easily from harness mode to high-back booster mode after 4 years by removing the base and using the vehicle seat belt and integrated connectors.
  • SLIDETECH®2 technology allows the seat to rotate and slide out of the car by up to 27 cm when used with the FamilyFix Slide Pro base, reducing strain when lifting your child in and out.
  • 360° one-hand rotation in any reclined position while in harness mode for effortless daily use.
  • i-Size compliant (R129/04) safety shell for high levels of protection throughout all stages.
  • G-CELL Side Impact Protection with additional G-CELL bumper to help absorb and disperse impact forces.
  • Patented AirProtect® Safety Cushions in the headrest to reduce the risk of head injuries in a side collision.

With the optional Newborn inlay, it can be used from birth (40 cm), including for premature babies, providing gentle support and a secure, ergonomic position during those first weeks and months. As the baby grows, the inlay can continue to be used up to around 75 cm, ensuring comfort and stability through early development.

From around 3 months (61 cm) up to approximately 4 years old (105 cm or 16.5 kg), the Pearl XL Slide Pro is used in harness mode on the FamilyFix Slide Pro base. During this stage, the seat benefits from SLIDETECH®2 technology, allowing it to rotate and slide out of the car by up to 27 cm, making lifting a child in and out far easier and reducing strain on parents’ backs. Advanced safety features including G-CELL Side Impact Protection and patented AirProtect® Safety Cushions help protect the child in the event of a collision, while full i-Size (R129/04) compliance ensures high safety standards throughout everyday use.

Once a child reaches around 4 years old or 105 cm, the Pearl XL Slide Pro transitions into high-back booster mode. The base is removed, and the seat is installed using the vehicle’s seat belt along with integrated connectors to keep it stable in the car. The harness and padding can be neatly stored away without removing them, making the changeover simple and stress-free. In booster mode, the seat continues to provide excellent protection and support as the child grows, remaining suitable up to approximately 12 years old.

Comfort is maintained at every stage of growth. Five recline positions allow the seat to adapt whether a child is sitting upright or sleeping, while the height-adjustable headrest grows with them to provide ongoing support. Breathable ClimaFlow fabrics, ventilation panels and mesh materials help regulate temperature throughout the year, keeping children comfortable in all seasons. Optional accessories such as a premium organic cotton car seat cover and an extra-large sun canopy offer additional softness and protection from sunlight when needed.

Overall, the Maxi-Cosi Pearl XL Slide Pro offers a thoughtfully designed, long-term car seat solution that adapts through every phase of childhood, combining advanced safety, everyday ease of use and lasting comfort from birth right through to the point a car seat is no longer required.

Frequently Asked Questions

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.

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.

Why is my headrest not going all the way up?

In harness mode (for children from 0 to 4 years / up to 105 cm), the headrest can be adjusted to 6 positions. Once your child reaches 100 cm, you can switch to booster mode by storing away the harness. In booster mode, the headrest can be adjusted from position 6 to 15. So remember: - Harness mode (0 – 4 years): Headrest positions 0 – 6 (Use the harness and pair with the FamilyFix car seat base) - Booster mode (4 – 12 years): Headrest positions 6 – 15 (Use the vehicle belt and integrated connectors)

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.
