10 Best Car Seat For 4 Year Olds 2025 in the United States

The Graco Extend2Fit Convertible Car Seat is designed to grow with your child, making it a good choice for 4-year-olds who still need a secure harness system. It offers both rear-facing and forward-facing options, which is great since rear-facing use is safer for younger children and the seat supports rear-facing up to 50 pounds — higher than many seats. For older toddlers, it converts to forward-facing with a 5-point harness and can hold children up to 65 pounds. One standout feature is the adjustable extension panel that gives extra legroom, helping your child stay comfortable on longer rides.

The no-rethread headrest and harness make adjustments easy as your child grows, so you don’t have to fuss with complicated straps. The seat installs using the LATCH system, which is common and generally straightforward, though the seat itself is on the heavier side at around 19 pounds, making it less convenient to move frequently between vehicles. Safety is a priority here, with Graco’s ProtectPlus Engineering that provides solid crash protection. The materials used are durable and comfortable, with a soft cotton-like cover. The seat also offers multiple reclining positions to keep your child comfortable.

It is important to note that car seats have expiration dates (usually around 6 years), so be sure to check that before purchasing or using a seat. This seat is a strong pick for parents wanting a versatile, safe, and comfortable option for their 4-year-old that can last through several growth stages.

The Graco Extend2Fit Kenzie 2-in-1 Convertible Car Seat is designed to accommodate children from infancy up to toddler years. It supports a weight range of 4-50 pounds in the rear-facing position and 22-65 pounds when forward-facing, making it a versatile option for growing children. The car seat features a robust steel construction and meets US FMVSS 213 crash test standards, ensuring a high level of safety.

Its Graco ProtectPlus Engineering includes advanced side-impact testing and a 5-point harness system for added security. The no-rethread headrest and harness adjust easily to fit your child as they grow, and the harness storage pockets provide convenience for parents when placing their child in the seat. Comfort is also a priority with up to 5 inches of additional legroom for rear-facing positions and 10 reclining options.

The compact size (21.5” depth x 19.5” width x 23.5” height) and lightweight design (19.25 pounds) make it relatively easy to handle and install. The InRight LATCH system simplifies installation with a one-second attachment feature and an audible click to confirm secure installation. Additionally, the car seat is fully recyclable, which is a plus for environmentally conscious families. However, some users might find the size a bit bulky for smaller vehicles, and the weight might be a concern for frequent transfers between cars. Nevertheless, the Graco Extend2Fit Kenzie stands out as a reliable and comfortable car seat option for your growing child.

The Graco 4Ever DLX 4-in-1 car seat offers a versatile solution that grows with your child, designed to be used for up to 10 years. It transitions seamlessly from rear-facing for infants to forward-facing for toddlers, and eventually to a highback and backless booster seat. This makes it an excellent long-term investment for parents looking for a car seat that can adapt to their child’s changing needs.

The seat supports a wide weight range, from 4 to 65 pounds for rear and forward-facing positions and up to 120 pounds as a booster, making it suitable for children up to approximately 10 years old or 52 inches tall. The Graco ProtectPlus Engineering ensures a high level of safety by safeguarding against frontal, side, rear, and rollover crashes. The Simply Safe Adjust harness system, which allows for easy height adjustments, and the 6-position recline add to the comfort and convenience, ensuring your child’s comfort on long drives.

Installation is made simple with the InRight LATCH system, and the integrated belt lock-off ensures secure vehicle seat belt installation. The RapidRemove cover, which can be machine-washed and removed in 60 seconds without uninstalling the seat, adds convenience for parents. Additionally, the fuss-free harness storage helps keep the harness out of the way while transitioning to booster mode. However, the car seat is relatively heavy at 22.8 pounds, which might make it less portable for frequent transfers between vehicles. Some users may also find the initial setup and adjustments a bit complex.
