The Maxi-Cosi Coral XP consists of two parts: an outer shell and an inner carrier that can be removed for use outside of the vehicle. While the total weight of the car seat with outer shell is 12 pounds, the Coral XP inner carrier weighs 5 pounds and can be carried cross-body or from its handle.
Total weight considered, the lightest car seats are the Nuna PIPA Lite, Nuna PIPA Lite R, and Nuna PIPA Lite LX, weighing less than 6 pounds. The Nuna PIPA Lite series of car seats are made with a proprietary lightweight foam not seen in any other car seats, which helps to make them 2.6 pounds lighter than the original Nuna PIPA and the PIPA RX.
Also adding to the weight savings: The PIPA Lite versions do not have seatbelt paths for installing the car seat without the base. Therefore, the PIPA Lite, Lite R, and Lite LX must be used with the base at all times.

One note: Measurements for Nuna car seats do not include the canopy or infant insert. With those accessories, Nuna car seats are as light as 6.7 pounds—still lighter than any other car seat. Most infant car seats weigh 9 to 11 pounds.
Looking for a car seat for an older child? The lightest toddler car seat is the WAYB Pico, which weighs just 8 pounds and is foldable for travel. The WAYB Pico can be used only forward-facing and is recommended for children age 2 and older.
