NARROW BOOSTER SEAT – Our booster seat is designed for kids aged 4+ years, weighing 40–100 lbs, and 43.5–59 inches tall. TRAVEL FRIENDLY – The Mifold comfort booster fits into regular backpacks and glove boxes. It’s perfect for carpooling, ride sharing and much more. INCLUDES EXTRA PADDED SEAT CUSHION – The new version includes a cushioned “Compact Comfort” seat cushion for extra comfort during long rides. It also includes an updated shell for better support, anti-slip pads to keep the seat in place, and an easy-to-use shoulder belt guide. SECURE FIT – Mifold ensures optimal seat belt fit. Instead of lifting the child up, the grab-and-go car seat adjusts the adult seat belt by pulling it down to fit the child safely. NO INSTALLATION REQUIRED – Setup is quick and easy. The booster seat works in any car with a standard 3-point seat belt.
