Maxi-Cosi Pearl XL Slide Pro

Maxi-Cosi Pearl XL Slide Pro Car Seat

The Maxi-Cosi Pearl XL Slide Pro is a premium i-Size car seat designed to grow with your child from around 3 months up to 12 years (40–150cm). Combining advanced safety technology with everyday practicality, it offers long-term value, outstanding protection and exceptional ease of use for busy families.

Approved to the latest R129 i-Size standards, the Pearl XL Slide Pro delivers enhanced safety at every stage. Integrated G-CELL side impact protection and AirProtect® headrest technology work together to reduce forces in the event of a collision, helping to protect your child’s head, neck and body.

When used with the compatible FamilyFix Slide Pro base, the seat features innovative SlideTech® technology, allowing the car seat to slide out towards you for effortless access. This reduces strain on your back and makes getting your child in and out of the car quicker and easier. The seat also offers 360° rotation, even when reclined, for added convenience.

Designed to adapt as your child grows, the Pearl XL Slide Pro transitions smoothly from a 5-point harness seat to a high-back booster using the vehicle seatbelt. The adjustable headrest and multiple recline positions ensure a comfortable, supportive fit throughout childhood, whether your child is awake or asleep.

Premium ClimaFlow breathable fabrics help regulate temperature, keeping your child cool and comfortable on every journey. Practical features such as an easy-in harness and removable, machine-washable covers make everyday use simple and stress-free.

The Maxi-Cosi Pearl XL Slide Pro is an ideal choice for parents looking for a long-lasting, high-safety car seat that combines smart design, comfort and ease of use from babyhood right through to the school years.

• 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.
  
  
• Is the Newborn inlay included with the Pearl XL Slide Pro?
  The Newborn inlay is sold separately as an accessory. The Newborn inlay makes it possible for your little one to travel in Pearl XL Slide Pro from birth through their first months (40 – 60 cm), and they can carry on using it up to 75 cm when they outgrow it.
  
  
• 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.
  
  
• What are the 4 different age stages that apply to this car seat?
  1) From 0 – 1 year (40 – 60 cm): Rearward-facing position with Newborn Inlay, using the integrated harness and FamilyFix Slide Pro base. 2) From 1 – 4 years (61 – 105 cm / 16.5 kg): Rearward-facing position with optional use of the Newborn Inlay (< 75cm), using the integrated harness and FamilyFix Slide Pro base. 3) From 15 months – 4 years (76 – 105 cm / 16,5 kg): Forward-facing position , using the integrated harness and FamilyFix Slide Pro base. 4) From 4 – 12 years (100 – 150 cm): Forward-facing position, using the vehicle belt without the base. At this stage, the 360° rotation and SLIDETECH® functions are no longer available. It is advised to install the seat with the integrated connectors for extra safety and stability.
  
  
• 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)
  
  
• What is the easy-in harness?
  The 5-point safety harness with easy-in feature makes getting your child in and out their seat simple. When unbuckling the harness, the shoulder pads spring upwards and stay open to make room for easy access.
  
  
• 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.
  
  
• When should I convert to booster mode?
  Use the base and harness up to 16.5 kg (around 100 cm/4 years). After that, remove the base, store away the harness and buckle, and switch to booster mode.
  
  
• Where should I store away the harness and the buckle?
  The harness can be stored in the backrest of the seat, while the buckle can be stored in a lie-flat, locked position integrated into the seat. This prevents the harness from being used instead of the vehicle seat belt. The buckle will only be released once the integrated connectors are stored again.
  
  
• Can I rotate the Pearl XL Slide Pro on the base in any position?
  Yes, when the car seat is in harness mode (rearward-facing and forward-facing), you can easily and safely rotate the seat in any position, from fully upright to fully reclined. Please be aware that the FamilyFix Slide Pro base is sold separately.
  
  
• How do I operate the rotation function?
  When the seat is in driving position, you can unlock the rotation with the handles on both sides. When the seat is in lateral position, you can simply rotate the seat with one hand without touching the handle.
  
  
• 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.
  
  
• Do I always have to use the sliding technology?
  Use SLIDETECH®2 whenever you need or want to use it. If preferred, you can also use the one-hand rotation function without sliding. Please note: the sliding technology only works in combination with the FamilyFix Slide Pro base (sold separately).
  
  
• 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.
