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.
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.
What we liked
- Built around a modular system for extended rearward-facing use
- Strong safety pedigree from a Scandinavian rearward-facing-focused brand
- Base cost amortised across a longer usage period than a single-stage carrier
Where it falls short
- Base sold separately, adding to the total cost
- No pushchair travel-system click-fit like the CabrioFix or Pipa Urbn
- Doesn't rotate, unlike the Cybex Cloud T
