Your baby must travel in an approved rear-facing infant car seat from their very first journey, and these seats are specifically engineered to provide the safest possible protection for a newborn's head, neck, and spine.

Group 0+ vs i-Size – Which Infant Car Seat Standard Is Right for You?

• Group 0+ (ECE R44) – The older standard. Rear-facing from birth to 13kg (approximately 12–15 months). Widely available and compatible with most ISOFIX bases. A safe, proven choice.
• i-Size (R129) – The newer, stricter standard. Classified by height rather than weight. Rear-facing mandatory until at least 15 months. Requires ISOFIX installation. Includes more rigorous side-impact testing. Recommended for maximum protection.
• Our verdict – If you're buying new, choose i-Size where possible. The enhanced side-impact protection and mandatory ISOFIX installation make it the safer choice for your newborn.

Travel System Compatibility

Many infant car seats in this range are compatible with pushchair frames, allowing the seat to click directly onto a travel system without disturbing a sleeping baby. The Doona range goes further – the car seat converts into a stroller in seconds, eliminating the need for a separate pushchair entirely. Check individual product pages for travel system compatibility.

How to Choose the Right Infant Car Seat

• ISOFIX vs seatbelt – ISOFIX installation is safer and more convenient. Check your car has ISOFIX anchor points (most cars made after 2004 do).
• Travel system use – If you want to use the seat on a pushchair frame, check compatibility with your pram before purchasing.
• Weight limit – Group 0+ seats are suitable to 13kg; i-Size seats are classified by height. Check the specific seat's limits.
• Newborn insert – Most infant seats include a newborn insert for smaller babies – check when this should be removed as your baby grows.
