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

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 TurboBooster 2.0 LX Highback Booster Seat is a solid choice for parents looking for a car seat for their 4-year-olds. Designed for children aged 4 to 10 years old, it can support weights from 40 to 100 pounds and heights up to 57 inches, making it suitable for extended use. The seat boasts Graco's ProtectPlus system, which is designed to guard against frontal, rear, and rollover crashes, providing reassurance regarding your child's safety. Additionally, the incorporation of EPS energy-absorbing foam adds an extra layer of protection in the event of impact.

The one-hand front-adjust LATCH system simplifies the installation process, ensuring the seat is securely fastened to the vehicle seat. In terms of comfort, the fully adjustable headrest ensures that the seat can be adapted as your child grows, and the removable, machine-washable seat pad makes it easy to keep clean. The inclusion of a cup holder and hideaway storage compartment adds convenience by keeping drinks, snacks, and small toys within easy reach for your child.

However, it's important to note that this seat has a 3-point harness system, which might be less secure compared to a 5-point harness found in some other models. Also, the car seat is polyester material, which, while durable, may not be as breathable as some other fabrics, potentially making it less comfortable in hotter climates. Lastly, the seat has only one reclining position, which might limit comfort during long trips. Despite these minor drawbacks, the Graco TurboBooster 2.0 LX stands out for its safety features, ease of use, and practical conveniences, making it a worthy consideration for parents.

The Graco Tranzitions 3-in-1 Harness Booster Seat is a versatile car seat that grows with your child, transitioning from a forward-facing harness seat to a highback booster and then to a backless booster. This adaptability makes it a cost-effective option for parents, accommodating children from 22 to 100 pounds. The 5-point harness system and the Simply Safe Adjust Harness System, which allows adjustments with one hand, contribute to its user-friendly design.

Safety is a significant focus, with Graco ProtectPlus engineering ensuring protection in various crash scenarios, meeting rigorous US FMVSS 213 standards. The eight-position adjustable headrest and machine-washable seat pad and covers add to the comfort and convenience, making it easy to keep clean and suitable for growing children. Additionally, the two cup holders provide practical storage for drinks and snacks, a handy feature for parents on the go.

On the downside, the car seat is only forward-facing, which may not suit all parents' preferences for extended rear-facing usage. At 17.19 pounds, it is relatively lightweight, making it portable but potentially less robust than heavier models. Installation via seat belt may be less straightforward compared to models with LATCH system compatibility. Despite these minor drawbacks, the Graco Tranzitions 3-in-1 is a reliable and easy-to-use choice.
