10 Best Booster Seats 2026 in the United States

The Graco Tranzitions 3-in-1 Harness Booster Car Seat is designed to grow with your child from toddler to youth, covering weights from about 26.5 to 100 pounds and heights up to 57 inches. It starts as a forward-facing harness seat, then converts to a highback booster, and finally to a backless booster, making it a flexible option that can last through multiple stages of your child’s growth. The harness system is easy to adjust with a no-rethread feature, allowing the headrest and harness to move together, simplifying safety adjustments as your child gets taller.

Installation uses the LATCH system, which many parents find straightforward and secure. The seat is lightweight and portable, making it convenient for busy families who need to move it between vehicles. Comfort is addressed with nine recline positions and a padded, machine-washable cover that helps with cleaning. Safety-wise, this booster has a 5-point harness for the younger stages and meets industry standards for weight limits.

On the downside, while the weight range is broad, the minimum weight for switching to booster mode starts at 40 pounds, which is slightly higher than some other seats, possibly limiting use for smaller kids earlier on. Additionally, some families might find the seat’s size a bit bulky compared to simpler backless boosters, especially for smaller cars. This booster seat suits parents wanting a durable, adaptable seat that balances safety, comfort, and ease of use.

The Graco TurboBooster 2.0 LX Highback Booster Seat in Gannon model offers a versatile and safe option for children aged 4-10 years, weighing between 40-100 lbs and up to 57 inches tall. This booster seat excels in safety with Graco's ProtectPlus system, which provides protection against frontal, rear, and rollover crashes, and includes EPS energy-absorbing foam for effective impact management. The one-hand front-adjust LATCH system ensures easy and secure installation, making it user-friendly for caregivers.

The seat's ability to convert from a highback to a backless booster extends its usability as your child grows, offering long-term value. Comfort is well catered with a fully adjustable headrest and a removable, machine-washable seat pad, ensuring ease of maintenance. Additionally, a cup holder and a hideaway storage compartment add convenience by keeping drinks, snacks, and favorite items within reach.

However, the seat is forward-facing only, which may not suit all needs, and it has just one reclining position, potentially limiting comfort for some children. Despite these minor drawbacks, the Graco TurboBooster 2.0 LX stands out as a reliable, comfortable, and easy-to-maintain booster seat, receiving high praise with a 4.7-star rating from over 54,000 reviews.

The Graco Turbobooster 2.0 Backless Booster Seat is designed for children aged 4 to 10, supporting weights from 40 to 100 pounds and heights up to 57 inches. This booster is well-suited for parents looking for an easy-to-use, forward-facing seat that relies on the vehicle's seat belt for installation, making it simple but requiring that your car's belt fits your child properly. Its backless design offers portability and comfort, featuring height-adjustable armrests and handy hide-away cup holders, which kids will appreciate during trips. The seat pad is machine-washable, helping parents keep it clean without hassle.

Safety is a strong point here, with Graco's ProtectPlus Engineered technology that covers various crash scenarios including frontal, rear, and rollover impacts, adding peace of mind with rigorous testing that meets or exceeds US standards. However, the lack of latch connectors means the booster is less secure than some models that offer both belt and latch installations. Also, being backless, it may not provide the same head and neck support as high-back boosters, which could be a consideration depending on your child's needs and car type.

This booster represents a solid choice for families wanting a reliable, comfortable, and well-reviewed seat for bigger kids transitioning out of harnessed car seats, especially if your focus is on ease of use and cleaning.
