Joie Steadi R129 Birth to 4 Years Car Seat in Shale

The Joie Steadi R129 is a convertible car seat designed to provide safe and comfortable transport for children from birth up to approximately four years of age. It transitions from a rear-facing seat suitable for infants to a forward-facing seat for toddlers, accommodating children from 40cm to 105cm in height and up to 18kg in weight. The seat is certified to the latest R129 (i-Size) safety standard, which includes rigorous side-impact testing, offering parents enhanced peace of mind regarding their child's protection during travel. Key features include the exclusive Tri-Protect headrest with Intelli-Fit memory foam, which is engineered to absorb energy in the event of a side collision. The Grow Together adjustment system allows the headrest and integrated five-point harness to be raised simultaneously without the need to re-thread the straps, making it easier to adapt the seat as your child grows. For comfort, the seat offers four recline positions: one for rear-facing use and three for forward-facing, helping to keep children content on longer journeys. The plush cushioning and removable, machine-washable cover in a Shale colourway make maintenance straightforward. This car seat is installed using your vehicle's existing three-point seat belt, featuring dual lock-offs and a large belt path to facilitate a secure and correct fit. It is not compatible with ISOFIX bases. The padded infant head and body support inserts provide extra cosiness for smaller babies. With its practical design, up-to-date safety credentials, and adaptable features, the Joie Steadi R129 is a solid, long-term choice for families seeking a single car seat that will see their child through the infant and toddler stages.
