Buying advice

When choosing a narrow booster seat, measure your vehicle's back seat width and check the seat's width to ensure it fits three across if needed. Look for features like LATCH for stability, adjustable headrests for a proper belt fit, and machine-washable covers for easy cleaning. Safety certifications (JPMA/ASTM) and consumer reviews are key indicators of reliability.
