Quick answer
Choose the Doona i if you want a fully integrated car seat and stroller that meets the strictest i-Size safety standards. Pick the Doona+ for a lighter, more affordable option that still converts to a stroller in seconds.
Safety and certification differences
The Doona i is R129 certified, meaning it meets the European i-Size safety regulation. This standard includes side-impact protection and a more rigorous testing protocol. The Doona+ also converts from car seat to stroller but does not carry the same i-Size certification, which may matter if you prioritize the latest safety benchmarks.
Design and comfort upgrades
The Doona+ features an updated all-black seat cover with improved textiles and enhanced breathability, designed for comfort during longer outings. The Doona i retains a classic design with a 5-point harness that distributes forces evenly across your baby’s shoulders and hips. Both offer quick conversion, but the Doona+ places more emphasis on modern style and airflow.
Trade-offs to consider
- Safety certification: Doona i has i-Size (R129) certification; Doona+ does not.
- Price: Doona i is $295.26 (catalog comparison $399.00); Doona+ is $224.25 (catalog comparison $299.00). Doona+ saves about $71, making it more budget-friendly.
- Integrated system: Both convert from car seat to stroller in seconds, but Doona i is a fully integrated travel system from the start.
