German-designed and engineered to meet the highest safety standards, the Britax Monarch Belt-Positioning Booster was developed to grow with your child. It features True Side Impact Protection and innovative comfort features. Deep head and side wings cocoon the child's head, shoulders and entire torso in the event of a crash, spreading the force over a larger area reducing risk of serious injury. The strong sturdy shell is made to prevent the car from invading the seating area, further protecting the child. For a relaxing, comfy ride, the seat has three layers of padding, pressure-mapped for comfort. Color-coded belt route guides assure proper lap and shoulder belt positions, and a one-hand height adjustment headrest means your child will be comfortable and safe through those growth spurts. The plush fabric cover removes for washing, and the soft-touch armrests expand for wider seating. The seat also has two retractable cup holders, and it easily converts to a backless booster. For children 38-60 inches tall, weighing 25-100 lbs. Lightweight booster weighs only 15 lbs. Dimensions: Dimensions 15.5"L x 17.5"W x 27.5"H
