Joie i-Irvana Max i-Size Extended Harness Booster Seat – Dark Gray charcoal

The Joie i-Irvana Max is a 2-in-1 car seat that grows with your child for years, combining a secure 5-point harness for younger children with a full belted booster mode for older ones all in a single i-Size certified seat. Suitable from 15 months right through to approximately 12 years, it's designed to remove the need to buy (and re-fit) a separate seat as your child grows.

In 5-point harness mode, the i-Irvana Max is suitable from 15 months and 76cm up to 125cm and 25kg (approx. 7 years), installed using ISOFIX and top tether for a firm, stable fit. Once your child outgrows the harness, the seat converts to belted booster mode, suitable from 100cm to 150cm and up to 36kg (approx. 3.5 to 12 years), installing quickly and securely with the vehicle's own seat belt with ISOFIX available as an optional extra point of stability in booster mode too.

Safety runs through every stage of that journey. The seat meets the highest ECE R129 safety standard, including rigorous side-impact testing, and carries i-Size certification throughout. The soft, padded 5-point harness keeps younger children properly secured, while the 15-position headrest offers custom protection at every growth spurt, from toddler through to pre-teen.

Comfort is built in with genuine day-to-day use in mind. The one-hand Grow Together headrest and harness adjust simultaneously, so there's no re-threading the harness straps as your child grows a common frustration with other harnessed seats. Ventilated sides and mesh fabrics help keep things comfortable on warmer journeys, while a plush memory foam seat pad and 3-position AutoAdjust seat depth keep growing legs properly supported.

When it's time to clean up, the mesh seat covers are fully removable and machine washable, and the seat's sleek, lightweight design makes it easier to move between cars if needed.
