DESC: The Britax Monarch™ belt-positioning booster is a revolution in child safety. Designed to grow with your child, this seat boasts 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 shell is made to prevent the car from invading the seating area, further protecting the child. Pressure mapped for comfort, extra padding has been added to the seating area to ensure a relaxing, comfy ride. Color-coded belt route guides properly position the lap and shoulder belts, and a four-position headrest means your child will be comfortable and safe. The seat fits children up to 60 inches and features plush, washable fabrics, soft-touch arm rests, a retractable cup holder, expandable base and can be used as a backless booster.
