Joie Signature i-Plenti™, i-Size Car Seat 76-150 cm
A premium car seat designed to grow with your child for years. The Joie Signature i-Plenti™ is an i-Size car seat for children from 76 to 150 cm, with harness use up to 105 cm and high-back booster mode up to approximately 12 years.
Joie i-Plenti: a premium evolving car seat for childhood
The Joie Signature i-Plenti™ is designed for families looking for a safe, comfortable and long-lasting car seat after the infant carrier stage. It covers children from 76 cm to 150 cm, accompanying them from approximately 15 months to 12 years.
During the first stage, it is used forward-facing with a 5-point harness up to 105 cm or 19.5 kg. Later, it converts into a high-back booster seat, using the vehicle seat belt from 100 to 150 cm.
Its steel-reinforced shell, Guard Surround Safety™ panels, Tri-Protect™ headrest with Intelli-Fit™ foam and ECE R129/03 i-Size approval make it one of the most complete evolving car seats in the Joie Signature range.
Why choose the Joie Signature i-Plenti?
Extended harness use
Allows the 5-point harness to be used up to 105 cm or 19.5 kg for controlled protection over a longer period.
i-Size R129 safety
Meets the demanding ECE R129/03 standard, including side impact testing and i-Size certification for compatible vehicles.
Grows up to 150 cm
After the harness stage, it becomes a high-back booster up to 150 cm, supporting your child for years.
From harnessed car seat to high-back booster
The i-Plenti offers two clear stages of use. First, it works as a forward-facing harnessed car seat from 76 to 105 cm, provided the child is over 15 months old and weighs less than 19.5 kg.
As the child grows, it converts into a high-back booster from 100 to 150 cm, using the vehicle seat belt with colour-coded guides for intuitive positioning.
A strong structure designed for severe impacts
The Joie Signature i-Plenti features a steel-reinforced frame that increases the structural rigidity of the seat and helps maintain its integrity during an impact.
This reinforcement adds stability, strength and durability, especially important in a car seat designed to accompany your child for more than a decade.
Grows in height and width with your child
The AutoAdjust™ shoulder panels automatically expand as the headrest is raised, providing more room for shoulders, back and torso.
This allows the seat to grow not only in height, but also in width, maintaining a comfortable and natural position throughout its use.
9-position one-hand adjustment
The Grow Together™ system allows the headrest and harness to be adjusted simultaneously in 9 positions with one hand, even when the seat is installed in the car.
There is no need to rethread the harness or reinstall the seat as your child grows. When switching to booster mode, the 5-point harness stores neatly inside the seat.
Three positions for restful journeys
The Joie i-Plenti includes 3 recline positions to adapt your child’s posture to each journey.
Your child can sit more upright when awake or recline when they need to rest, without having to reinstall the seat.
Guard Surround Safety™, Tri-Protect™ and Intelli-Fit™
The Guard Surround Safety™ panels add extra protection against side impacts. The Tri-Protect™ headrest features three layers of protection, including Intelli-Fit™ memory foam.
This combination helps protect the head, neck and spine throughout every stage of growth.
Elegance, safety and long-term comfort
The Joie Signature collection stands out for its neutral tones, high-quality fabrics, carefully crafted stitching and refined details.
The i-Plenti combines this premium design with practical features such as ISOFIX, Top Tether, AutoAdjust™, Grow Together™ and machine-washable covers.
Integrated ventilation and premium padding
Integrated side ventilation helps maintain pleasant airflow during all seasons, especially on long journeys or warmer days.
Its Signature padding delivers a soft, secure and comfortable feel throughout the full life of the seat.
