The RAC Port i-Size car seat takes your tiny passenger from birth (40cm) up to around 15 months old (87cm). It’s built for safety thanks to in-depth R129 safety testing compliance but if you install it using the Port i-Size ISOFIX base (sold separately) it meets the i-Size standard, making it even more adaptable and easy to use. Packed with Cosatto’s famous storytelling patterns that little ones love, combined with state-of-the-art safety and comfort technology, the rear-facing RAC Port i-Size delivers both reassurance and personality on the go.

It is available in a wide variety of Cosatto designs to create matching travel systems with the Giggle Mix, Giggle 3, Giggle Quad, Wow, Wow XL, Wowee and Wow Continental.

The current safety guidelines advise that newborn babies are not left in their car seat for longer than 30 minutes. For babies 2-6 months, no longer than 2 hours. It is also safer to keep your child rear-facing for as long as possible – a minimum of 15 months but ideally 4 years. A child should never be in their harnessed car seat with a thick winter coat or snowsuit on.
