Force Fit XL For Preschoolers and toddlers of one year and not weighing more than 20 pounds, convertible seats are important and can be placed facing forward though riding while rear facing is recommended. For the school aged children, booster seats come in handy as they have been specially designed for older children that have already outgrown car safety seats which are forward facing. http://www.strongtesterone.com/force-fit-xl/
