10 Best Narrow Car Seats 2025 in the United States

The Graco TurboBooster 2.0 Backless Booster Car Seat is a popular choice for parents, appreciated for its top consumer ratings and robust safety features. At just 6 pounds, the seat is lightweight, making it easy to move between vehicles. It's designed for children aged 4 to 10, accommodating weights from 40 to 100 pounds and heights up to 57 inches, making it a versatile option as your child grows.

The seat's width is compact, ideal for narrow car seats, while its modern design includes height-adjustable armrests and convenient hide-away cup holders to enhance comfort. Safety is a priority with Graco ProtectPlus engineering, which offers protection from various crash scenarios and meets U.S. safety standards. However, it lacks a LATCH system, relying solely on the vehicle's seat belt for installation, which might be less secure in some vehicles.

The polyester material is durable but requires careful cleaning as bleach can't be used. For ease of cleaning, a removable cover would have been beneficial. This booster is forward-facing only and doesn't have a harness, suitable for older children who can sit still during the ride. Parents looking for a stylish, comfortable, and safe booster seat for their growing child might find this to be an excellent option, especially in narrow car compartments.

On the downside, the seat lacks a harness system, which might be a concern for parents looking for additional security for children on the lighter end of the weight spectrum. Additionally, while the polyester material is durable, it might not offer the same level of comfort as other, more plush options. This backless booster seat is highly rated by customers, with a 4.8 out of 5 stars from over 27,000 reviews, indicating a high level of satisfaction. The Graco® TurboBooster® LX is efficient, user-friendly, and safe, making it a strong choice for families needing a reliable booster seat, though it may not be the best fit for extremely narrow car seats or those seeking a harnessed option.
