Looking for a car seat that combines extended harness safety, comfort, and easy installation? In our Joie i-Irvana Max car seat review, we explore why this R129 extended harness booster is such a standout choice for families. Designed to grow with your child from 15 months right up to 12 years, the Joie i-Irvana Max delivers maximum protection, comfort, and convenience for every journey.
Extended Harness Safety Up to 7 Years
The i-Irvana Max sets itself apart with its extended 5-point harness, which can be used until your child reaches 125cm (up to 25kg, around age 7). This means your child benefits from the superior safety of a harness for much longer than most other seats allow. The harness keeps little ones secure by protecting the strongest points of their body, and the soft padded covers keep it snug but comfortable.
One Seat for 12 Years of Travel
Suitable from 15 months and 76cm up to 150cm (approx. 12 years), this car seat adapts as your child grows. In harness mode, it supports little ones up to 125cm, then seamlessly converts into a high-back booster for older children. Instead of juggling multiple car seats over the years, the i-Irvana Max gives you a single, long-lasting solution.
i-Size Safety Certified
Parents want reassurance that they’re choosing the safest option, and the i-Irvana Max delivers. It meets the highest ECE R129/03 safety standards (the latest EU regulations) and is i-Size certified in every mode. With rigorous side-impact testing included, you can be confident your child is well protected from all angles.
Simple, Secure Installation
Getting car seats in and out can be stressful, but the i-Irvana Max makes it easy. The ISOFIX connectors and top tether provide a rock-solid, straightforward install in harnessed mode. When it’s time to switch to booster mode, you can use the seatbelt alone or combine it with ISOFIX for added stability.
No-Fuss Adjustments as They Grow
Gone are the days of re-threading harnesses every time your child has a growth spurt. What a hassle that used to be! The i-Irvana Max’s 15-position GrowTogether headrest and harness system adjusts simultaneously with just one hand, keeping things simple and stress-free for parents.
Plush Comfort for Every Journey
Children are more likely to sit happily when they’re comfortable, and Joie has thought of everything here. The seat is fitted with a memory foam cushion, ensuring softness and support on long trips, while padded harness covers stop straps from digging in.
Cool and Breathable Design
No one likes a hot, sticky car seat. The i-Irvana Max is designed with ventilated sides and breathable mesh fabrics to encourage airflow and keep your child cool and content, even on warm days or long journeys.
Adapts to Growing Legs
As kids get taller, cramped legs can make car journeys uncomfortable. With the 3-position AutoAdjust seat depth, you can extend the seat to give them more room, so they’ll be as comfortable at 10 as they were at 3.
Practical for Parents Too
Parenting is messy, and Joie has kept that in mind. The removable seat covers are machine washable, so inevitable spills, crumbs, and sticky fingers don’t have to mean a permanent mess. The seat is also streamlined and lightweight, making it easier to move between cars if needed.
With an RRP of £175, the i-Irvana Max is excellent value considering it covers such a wide age and size range. Instead of needing to replace your car seat multiple times as your child grows, this single seat will see you through all those stages, combining premium features, high safety standards, and long-lasting comfort in one affordable package.
