iZi Go Modular X1 i-Size Car Seat
7.8/10 overall£220.00 (carrier only, base sold separately)
A modular i-Size infant carrier designed to convert into a rearward-facing toddler seat on the same base as your child grows.
The verdict
BeSafe's iZi Go Modular X1 is designed to convert to a rearward-facing toddler seat on the same base, extending your child's rearward-facing travel well past 12 months per Scandinavian safety guidance. Best for parents prioritising extended rearward-facing use over pushchair click-fit convenience; the base is sold separately, adding to the total cost.
BeSafe's iZi Go Modular takes a different long-term approach: rather than being replaced entirely once your baby outgrows it, the carrier is designed to be swapped for a compatible toddler seat that clicks onto the same base later, keeping your baby rearward-facing for longer — which BeSafe (a Norwegian brand) builds around Scandinavian safety guidance favouring extended rearward-facing travel well past 12 months.
For parents who specifically want to prioritise extended rearward-facing use over the flexibility of clicking onto a pushchair, this system is a genuinely different value proposition to the CabrioFix or Pipa Urbn: you're buying into a modular system, not just a single infant carrier, so the base cost is amortised over a longer period of use.

Frequently asked questions
What makes the BeSafe iZi Go Modular different from a standard infant carrier?+
Rather than being replaced entirely once your baby outgrows it, the carrier is designed to be swapped for a compatible toddler seat that clicks onto the same base later, keeping your baby rearward-facing for longer — built around Scandinavian safety guidance from BeSafe, a Norwegian brand, favouring extended rearward-facing travel well past 12 months.
Does the base come included with the BeSafe iZi Go Modular X1?+
No — the base is sold separately, which adds to the total cost of the system, though that cost is amortised over a longer usage period than a single-stage carrier since the same base is used for the follow-on toddler seat too.
Can I click the BeSafe seat onto a pushchair?+
No — unlike the Maxi-Cosi CabrioFix or Nuna Pipa Urbn, it doesn't have pushchair travel-system click-fit, and it doesn't rotate like the Cybex Cloud T, since it's built around the modular base-and-seat system rather than click-and-go pushchair convenience for everyday use.
Why choose a rearward-facing-focused system over a rotating seat like the Cybex Cloud T?+
If you specifically want to prioritise extended rearward-facing use — a safety approach BeSafe builds around — over the flexibility of clicking onto a pushchair, this modular system is a genuinely different value proposition: you're buying into a modular system, not just a single infant carrier, amortised over a longer period of use.
