This seat saver has two stages that grow with your child. Its high-density foam construction prevents depression damage that is caused by car seats. The bottom tray keeps all car seats level and in proper position, and the kick plate protects upholstery from shoe scuffs. Works with all latch compatible car seat systems and fits all automobiles. Stage one, the bottom tray is used alone and works with all rear facing infant seats. Stage two, the back attaches to the bottom tray for use with forward facing toddler and booster seats. Available in black, gray and beige.
