Ultra-Lightweight Convertible Car Seat for Families Who Travel: The Maxi-Cosi Romi 2-in-1 Convertible Car Seat is engineered for families who refuse to choose between safety and simplicity. At just over 9 lbs, it's one of the lightest convertible car seats on the market, making every transfer—from car to car, plane to crib—feel effortless. Whether you're constantly switching vehicles, traveling frequently, or just tired of heaving a 15-pound car seat from one place to another, the Romi is built specifically with you in mind.
How the Maxi-Cosi Romi Works
The Romi's convertible design accommodates your growing child at every stage. Install rear-facing from birth through age 3 (5–40 lbs), then transition to forward-facing from age 1+ (22–40 lbs) as your child grows. The one-click LATCH system ensures secure installation in seconds, whether you're setting up for the first time or switching vehicles on a road trip. The top tether strap converts into a hands-free carrying strap that rests comfortably over your shoulder, so you can transport the car seat without straining your back.

Is the Maxi-Cosi Romi compatible with other strollers?
Yes, the Romi works with Maxi-Cosi strollers out of the box and most other major stroller brands with the appropriate adapter. Maxi-Cosi makes adapters for many popular stroller brands, and third-party universal adapters also work. For compatibility with your specific stroller, check your stroller's manual or contact the manufacturer. You can also reach Maxi-Cosi's customer care team at 1-800-951-4113.
What's the difference between rear-facing and forward-facing modes?
Rear-facing (birth to age 3, up to 40 lbs) provides maximum crash protection by cradling your baby's head and spine. Forward-facing (age 1+, 22-40 lbs) is for toddlers who've reached the minimum age and weight. The Romi transitions easily between modes with adjustable harness heights and buckle positions. The American Academy of Pediatrics recommends keeping children rear-facing as long as their car seat allows.
How much does the Romi car seat weigh?
The Romi weighs just over 9 lbs, making it one of the lightest convertible car seats on the market. This lightweight design is ideal for multi-car households, frequent travelers, or anyone who regularly moves the car seat between vehicles.
Can the Romi be used on an airplane?
Yes, the Maxi-Cosi Romi is certified for use on commercial aircraft. Install it in a window seat to avoid blocking the aisle. If the airplane lap belt is too short, request a belt extender from the flight attendant. When flying, store the lower anchor belt and tether strap and use only the aircraft lap belt for installation.
What makes the EcoCare fabric better?
EcoCare fabric is made from 100% recycled plastic bottles, giving discarded materials a second life while delivering premium comfort. The PureCosi™ padding is made without added fire retardant treatments, which many parents prefer to minimize chemical exposure while maintaining full safety standards.
Is the car seat easy to clean?
Absolutely. The seat pad and harness covers are completely removable and machine washable on a gentle cycle with cold water. Tumble dry on low heat for 10-12 minutes. Spot clean the buckle and car seat shell with warm soapy water and a damp cloth. Never submerge the buckle in water. This design makes maintaining hygiene simple with inevitable spills and messes.
How does the 1-click LATCH system work?
The LATCH system is a universal installation method in vehicles manufactured after 2002. Simply locate your vehicle's lower anchor bars, attach the Romi's hooks to them, and lock securely. For detailed installation instructions with photos, refer to your manual or contact ANB Baby's customer service team.
Can I use the Romi with a vehicle seat belt instead of LATCH?
Yes, you can install using your vehicle's lap/shoulder belt if you prefer or if your vehicle doesn't have LATCH anchors. However, use only one method—never combine LATCH and seat belt installation. Ensure your seat belt can lock securely by checking your vehicle owner's manual, and follow the detailed belt routing instructions in the Romi manual.
What is the warranty on the Romi?
The Romi includes a 1-year warranty from the date of original purchase against defective materials and workmanship. An original receipt is required. If you experience issues during the warranty period, contact Maxi-Cosi Consumer Care at 1-800-951-4113 (toll-free, US and Canada only) or visit www.maxicosi.com.
How long can I use the Romi?
Do not use the Romi more than 8 years after the manufacture date, which is printed on a label on the side of the car seat. If you're unsure of your product's age, Maxi-Cosi's customer care team can help identify it using your SKU.
